Hydraulics & Pneumatics - Hydraulics & Pneumatics is the leading international technical resource for fluid power http://hydraulicspneumatics.com/rss.xml en No Matter What, MINExpo is the Place To Be http://hydraulicspneumatics.com/blog/no-matter-what-minexpo-place-be <div class="node-body blog-body"><p>NFPA&rsquo;s International Economic Outlook Conference has become an annual event every August for hundreds of us in the fluid power industry. As much as I enjoy learning and writing about fluid power technology every month, it&rsquo;s always a welcome diversion to view our industry from a different perspective.</p> <div class="related-content"> <div class="related-label">Related</div> <p><a href="http://hydraulicspneumatics.com/mining/minexpo-opens-doors-leaders-mining-industry">MINExpo Opens Doors to Leaders in Mining Industry</a></p> <p><a href="http://hydraulicspneumatics.com/minexpo-international-2012">MINExpo International 2012</a></p> <p><a href="http://hydraulicspneumatics.com/other-components/mining-drill-provides-high-torque-small-space">Mining Drill Provides High Torque in Small Space</a></p> </div> <p>One interesting aspect is the world economy. For example, a few years ago Dr. Alan Beaulieu, president of ITR Economics, explained that many large U<ins cite="mailto:Config" datetime="2016-09-07T16:35">.</ins>S<ins cite="mailto:Config" datetime="2016-09-07T16:35">.</ins> companies have revenues that exceed the gross domestic product (GDP) of most countries in the world. Walmart would have the world&rsquo;s 25<sup>th</sup> largest economy&mdash;bigger than Norway&rsquo;s, and Exxon Mobil would rank 30<sup>th</sup>, just ahead of Thailand.</p> <p>More recently, Beaulieu compared individual U.S. state economies to national economies. California&rsquo;s economy is roughly equal to the GDP of France. New York &nbsp;is on par with Canada, Texas is comparable to Brazil, and Pennsylvania can hold its own with Switzerland. And with all the riches Saudi Arabia enjoys from oil, its GNP is about the same as that of my home state, Ohio.</p> <p>But that&rsquo;s some of the fun stuff. The tone became more somber when examining industries tied directly to fluid power. Construction equipment is probably the single largest segment. Construction has been undergoing some modest growth, and it is expected to continue&mdash;and maybe improve&mdash;over the coming year.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/2016_promo.jpg" style="width: 595px; height: 332px;" /></p> <p>Industrial production has also been okay, and several narrow sectors have even done pretty well. Mining, on the other hand, has logged some pretty low numbers of late&mdash;and it&rsquo;s not expected to show any significant improvement within the coming months.</p> <p>But rather than dwell on mining&rsquo;s low numbers, let&rsquo;s celebrate the coming of <a href="http://www.minexpo.com/" target="_blank">MINExpo</a> in 2016. Las Vegas hosts this event only once every four years, so if you don&rsquo;t embrace it now, you won&rsquo;t get another chance for a while. As our exhibitor list shows in the article beginning on page 29, more than 70 companies will be promoting their fluid power products and services at this year&rsquo;s MINExpo.</p> <p>Most of the exhibits, however, will display mining equipment. We&rsquo;ve published multiple articles from contacts made at MINExpo. So you can not only see lots of fluid power components, but also examine some pretty interesting and innovative designs. And while you&rsquo;re at it, marvel at the sheer size of some of this equipment.</p> <p>And who knows, when the next MINExpo rolls around, in 2020, the mining industry might be posting record numbers.</p> <p><a href="http://sourceesb.com" target="_blank"><img alt="" src="/site-files/globalpurchasing.com/files/uploads/2016/07/15/SourceESB_Lookin_For_Parts_Banner.jpg" style="width: 600px; height: 46px;" /></a></p> </div> http://hydraulicspneumatics.com/blog/no-matter-what-minexpo-place-be#comments Mining Events The Hitch Post Thu, 22 Sep 2016 19:57:00 +0000 40191 at http://hydraulicspneumatics.com PackExpo International 2016 http://hydraulicspneumatics.com/packexpo-international-2016 <div class="node-body event-body"></div> <h3 class="location-locations-header">Location</h3> <div class="location-locations-wrapper"> <div class="location vcard"> <div class="adr"> <span class="fn">McCormick Place</span> <div class="street-address"> 2301 S King D </div> <span class="locality">Chicago</span>, <span class="region">IL</span> <span class="postal-code">60616</span> <div class="country-name">United States</div> <span class="geo"><abbr class="latitude" title="41.851229">41° 51' 4.4244" N</abbr>, <abbr class="longitude" title="-87.617034">87° 37' 1.3224" W</abbr></span> </div> <div class="map-link"> <div class="location map-link">See map: <a href="http://maps.google.com?q=41.851229+-87.617034+%282301+S+King+D%2C+Chicago%2C+IL%2C+60616%2C+us%29">Google Maps</a></div> </div> </div> </div> <div class="field-desc"> <p>In 2016, Pack Expo International will be the world&rsquo;s largest processing and packaging show, with:</p> <ul> <li>More than 45,000 attendees from more than 40 vertical markets</li> <li>More than 7,000 international buyers from more than 130 countries</li> <li>More than 2,000 exhibiting companies occupying over more than 1 million net square feet</li> </ul> <p>The show floor buzzes with machinery in action, interactive learning hubs and networking lounges.

In response to this article, I received the following from one of our members:<br /> <br /> <em>&quot;As an engineer for a heavy equipment manufacturer, I have to take exception with your advice in your last post. I believe selecting a hydraulic oil, and then requesting the equipment manufacturer to design around that is putting the cart before the horse.<br /> <br /> It makes much more sense for the equipment manufacturer to design the system for temperature, life, component availability, cost, and the million other things that go into machine design.<br /> <br /> Would you tell Ford that you have a set of brake pads, and would like a car designed that could use them? No, you rely on the manufacturer to provide a system, and take their recommendation.&quot;</em><br /> <br /> Hmmm... looks like I&#39;m in trouble -- again. I feel a bit like David, being pounded by Goliath. This member didn&#39;t reveal which hydraulic equipment OEM he works for... but the mind boggles with possibilities.<br /> <br /> Needless to say, I don&#39;t agree with my colleague&#39;s assertion that the reliability-based strategy I advocated in my previous post is &quot;putting the cart before the horse&quot;. Let me explain with an example:<br /> <br /> Say I am about to acquire a 25 ton hydraulic excavator. And let&#39;s say for example, this machine is fitted with Rexroth pumps and motors.<br /> <br /> According to the pump manufacturer, optimum performance and service life will be achieved by maintaining oil viscosity in the range of 25 to 36 centistokes. I also know that in my location I expect to use an ISO VG68 weight hydraulic oil and the brand of oil I use has a viscosity index of 98.<br /> <br /> This being the case, Rexroth are telling me - indirectly of course, that if my new machine runs any hotter than 70 Celsius the performance and reliability of their pumps and motors will be less than ideal. Not only that, with 70 Celsius as the maximum operating temperature, the oil will last longer, the seals will last longer, the hoses will last longer and almost every lubricated component in the hydraulic system will last longer.<br /> <br /> So being the sophisticated buyer that I am, I say to the OEM - before I order the machine: &quot;I expect ambient temperatures at my location as high as 45 Celsius and under normal operating conditions (no abnormal heat load in the hydraulic system) I want this machine to run no hotter than 70 Celsius. If you deliver it to site and it runs at 85 Celsius (or whatever) on a 45 Celsius day, then you&#39;ll have a problem on your hands.&quot;<br /> <br /> I&#39;m not suggesting this approach is in the interests of the OEM - clearly it&#39;s not. It&#39;s going to make their life more complicated and cut into their after sale revenue. No, it&#39;s totally in the interests of the guy signing the checks to keep the machine running. Luckily for all the OEM&#39;s out there, very few machine buyers will approach a new equipment acquisition with this level of sophistication.<br /> <br /> But YOU can dare to be different. The next time you or the company you work for are looking to acquire hydraulic equipment, begin with the end in mind.

La log&iacute;stica de llevar y mantener equipo especializado y cables, la protecci&oacute;n del t&eacute;cnico y el equipo de condiciones peligrosas, el acceso a componentes dif&iacute;ciles de alcanzar, todo hace m&aacute;s complicado el proceso, lo que agrega tiempo y costo a la operaci&oacute;n.</p> <p class="rtejustify">Por lo general visualizamos equipo pesado &ndash; de agricultura, miner&iacute;a, construcci&oacute;n, en campo en medio de la nada o bajo la tierra en minas. Pero imag&iacute;nense el reto que representa una operaci&oacute;n de dragado offshore: flotando en un mar de fluido corrosivo, aislado y b&aacute;sicamente aut&oacute;nomo; adem&aacute;s con el equipo hidr&aacute;ulico ubicado en una sala de m&aacute;quinas oscura, ruidosa, caliente y de espacio reducido lejos de la sala de control.</p> <p class="rtejustify"><strong>La Aplicaci&oacute;n</strong></p> <p class="rtejustify"><a href="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/uploads/2016/09/lr-ellicottcustomcubeside3web.jpg" target="_self"><img alt="" src="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/LR-ellicott_custom_cube_side3WEB.jpg" style="width: 250px; height: 203px; margin: 10px; float: right;" title="La figura muestra como desciende el brazo de la draga para remover material desde el fondo del agua" /></a>Esa es la situaci&oacute;n que enfrenta la tripulaci&oacute;n de la draga Hillsboro Inlet en la costa este de Florida. El capit&aacute;n Woodworth &ldquo;Woody&rdquo; Draughon &ndash; quien inici&oacute; su carrera en dragas accionadas por vapor en el Canal de Panam&aacute;, junto con su asistente Scott Evans, han estado trabajando juntos en la operaci&oacute;n de trabajo continuo de la Hillsboro Inlet por m&aacute;s de 20 a&ntilde;os. Esta operaci&oacute;n mantiene el paso libre de arena&nbsp;tanto para el tr&aacute;fico de botes, como para drenaje,&nbsp;previniendo as&iacute;&nbsp;la inundaci&oacute;n durante tempestades.</p> <p class="rtejustify">La empresa Ellicot Dredges de Baltimore, es el fabricante de dragas m&aacute;s grande de los Estados Unidos y ha estado en el negocio desde 1885. Supli&oacute; las dragas utilizadas en la construcci&oacute;n del&nbsp; Canal de Panam&aacute;. Enfocados en la producci&oacute;n de dragas de succi&oacute;n con cortadores, su draga m&aacute;s grande tiene una capacidad de 2,000 yardas c&uacute;bicas por hora. El trabajo a bordo de la 1170-S Elicott, la tripulaci&oacute;n se mantiene ocupada manejando las labores de dragado y ejecutando el mantenimiento en un ambiente caliente, h&uacute;medo y salino. La draga cuenta con dos motores diesel &ndash; un Caterpillar C-27 y un C-9 de respaldo, que accionan una bomba de 9,000 gpm que empujan&nbsp; 400 yardas c&uacute;bicas de arena por hora desde el fondo de la draga hacia la playa ubicada a poca distancia.</p> <p class="rtejustify">Elicott ha trabajado de la mano del distribuidor local de Sun Hydraulics, Advanced Fluid Systems por los &uacute;ltimos 25 a&ntilde;os. AFS ha sido part&iacute;cipe en el desarrollo de las tecnolog&iacute;as utilizadas en las dragas. La 1170-S en Hillsboro Inlet utiliza entre 25 y 30 v&aacute;lvulas de cartucho Sun y cinco controles Sun para las v&aacute;lvulas direccionales y proporcionales.</p> <p class="rtejustify"><strong>El Reto</strong></p> <p class="rtejustify">Una de las v&aacute;lvulas electrohidr&aacute;ulica&nbsp;proporcional Sun, controla el winche de giro utilizado para ajustar la velocidad del brazo de la draga, y debe ser ajustada para lograr el desempe&ntilde;o deseado. Una vez a bordo de la draga uno se puede dar cuenta del reto que implica el ajustar esta v&aacute;lvula.</p> <p class="rtejustify"><a href="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Winch-controlled-dredge-armLRWEB.jpg" target="_self"><img alt="" src="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Winch-controlled-dredge-armLRWEB.jpg" style="width: 250px; height: 179px; margin: 10px; float: left;" title="Winches hidráulicos controlan el posicionamiento del brazo de la draga y un motor hidráulico rota el cabezal de corte que remueve material desde el fondo." /></a>Con el cabezal de corte en la proa de la embarcaci&oacute;n, la sala de control dos pisos sobre la cubierta, y la sala de m&aacute;quinas al otro lado y debajo de la misma, el proceso de ajuste fino de la v&aacute;lvula implica un sinn&uacute;mero de movimientos, subidas y bajadas por las escaleras para lograrlo. El capit&aacute;n debe llevar un programador port&aacute;til y cables hacia la sala de m&aacute;quinas, f&iacute;sicamente conectar el amplificador, efectuar los ajustes y salir nuevamente para operar los controles y evaluar los resultados. De principio a fin, el ajuste puede tomar horas para lograr un desempe&ntilde;o &oacute;ptimo.</p> <p class="rtejustify">Cuando Sun Hydraulics Corp., Sarasota, FL introdujo su Amplificador con Bluetooth Inclu&iacute;do, configurado con la aplicaci&oacute;n de dispositivos m&oacute;viles AmpSet Blue, John Caldwell de Advanced Fluid Sistems visualiz&oacute; una oportunidad. Como ingeniero de ventas de AFS por m&aacute;s de 25 a&ntilde;os, Caldwell ha trabajado de la mano con Ellicott en sistemas hidr&aacute;ulicos y el&eacute;ctricos. Conoce de primera mano los retos que implica la configuraci&oacute;n de un nuevo amplificador en las dragas y lo vio como un ejemplo perfecto de c&oacute;mo este nuevo m&eacute;todo de configuraci&oacute;n podr&iacute;a ahorrar tiempo, dinero y esfuerzo.</p> <p class="rtejustify">Sun Hydraulics es un l&iacute;der en el dise&ntilde;o y fabricaci&oacute;n de v&aacute;lvulas de cartucho de alto desempe&ntilde;o, bloques de mando, y paquetes integrados para mercados m&oacute;viles e industriales a nivel mundial. Con una l&iacute;nea de soluciones electrohidr&aacute;ulicas en continua expansi&oacute;n, trabaja de la mano con High Country Tech (HCT),&nbsp; una subsidiaria 100% de Sun, para desarrollar soluciones electr&oacute;nicas innovadoras para aplicaciones hidr&aacute;ulicas.</p> <p class="rtejustify"><strong>El Producto</strong></p> <p class="rtejustify"><a href="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Captain-adjusts-LRWEB.jpg" target="_self"><img alt="" src="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Captain-adjusts-LRWEB.jpg" style="width: 250px; height: 167px; margin: 10px; float: right;" title="Winches hidráulicos controlan el posicionamiento del brazo de la draga y un motor hidráulico rota el cabezal de corte que remueve material desde el fondo." /></a>El amplificador con Bluetooth de Sun, el primer producto de &eacute;ste tipo en la industria, ofrece una combinaci&oacute;n solenoide-conector compatible con las v&aacute;lvulas proporcionales de Sun en un paquete compacto. Y si, hay una aplicaci&oacute;n disponible para usarlo. El usuario configura el amplificador sin necesidad de conectar cables (wireless), utilizando la aplicaci&oacute;n AmpSet Blue en su dispositivo iOS o Android para una calibraci&oacute;n f&aacute;cil, r&aacute;pida y confiable.</p> <p class="rtejustify">AmpSet Blue le permite a los usuarios ubicar y conectarse con el amplificador en cuesti&oacute;n utilizando su dispositivo m&oacute;vil y ajustar los par&aacute;metros del controlador proporcional a trav&eacute;s de varias pantallas sencillas. Esto elimina la necesidad de llevar un programador separado o un laptop costoso con cables especiales. Con la aplicaci&oacute;n, los usuarios pueden darle nombre a cada dispositivo y guardar o compartir configuraciones para uso futuro. Por seguridad, la configuraci&oacute;n de un dispositivo puede ser protegida con clave para evitar la modificaci&oacute;n sin autorizaci&oacute;n.</p> <p class="rtejustify">El amplificador es certificado a la &uacute;ltima revisi&oacute;n de las normas CE, incluyendo la 30-V/m automotriz (de acuerdo a la directiva 2009/09/19/EC). Debido a que es completamente encapsulado y sellado a IP69K &ndash; y ofrece protecci&oacute;n contra vibraci&oacute;n, golpe y condiciones ambientales &ndash; est&aacute; dise&ntilde;ado para ser instalado en ambientes hostiles, incluyendo la casa de m&aacute;quinas de dragas de agua salada.</p> <p class="rtejustify"><strong>La Instalaci&oacute;n</strong></p> <p class="rtejustify">Caldwell contacto a Draughon, le propuso la instalaci&oacute;n del nuevo amplificador con Bluetooth y se fue a Hillsboro Beach. Debido a que no requiere de un programador o laptop especial con cables, todo lo que se requiri&oacute; para una instalaci&oacute;n exitosa fue el amplificador en cuesti&oacute;n y el tel&eacute;fono m&oacute;vil de Draughon.</p> <p class="rtejustify"><a href="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Blue_6305LRWEB.jpg"><img alt="" src="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/11/Blue_6305LRWEB.jpg" style="width: 250px; height: 378px; margin: 10px; float: left;" title="A pesar que la válvula proporcional se encuentra ubicada en un lugar de difícil acceso en la sala de máquinas cerca de la proa de la embarcación, comunicación Bluetooth permite hacer ajustes a una distancia considerable de las válvulas." /></a>Para instalar el nuevo amplificador, desconectaron el conector del cable, removieron la bobina o solenoide como normalmente se hace, instalaron el nuevo amplificador Bluetooth en la v&aacute;lvula, apretaron la tuerca y reinstalaron el conector. Tiempo de instalaci&oacute;n: menos de cinco minutos.</p> <p class="rtejustify">Para configurar el amplificador, Draughon abri&oacute; la tienda de aplicaciones en su tel&eacute;fono, escribi&oacute; &ldquo;Sun Hydraulics&rdquo; en el buscador, seleccion&oacute; la aplicaci&oacute;n AmpSet y la instal&oacute;&nbsp; mientras esperaba en la cubierta de la draga en minutos.</p> <p class="rtejustify">Luego revis&oacute; las diferentes opciones de configuraci&oacute;n y fue a la sala de m&aacute;quinas para confirmar la conexi&oacute;n con el amplificador. Cada vez que abres la aplicaci&oacute;n empieza a escanear por dispositivos de Bluetooth disponibles que est&eacute;n en rango. Cuando el capit&aacute;n inici&oacute; la aplicaci&oacute;n, identific&oacute; el nuevo amplificador instalado. La aplicaci&oacute;n se conect&oacute; con el mismo y la luz se encendi&oacute; en azul indicando que la conexi&oacute;n fue exitosa y que se podr&iacute;a iniciar la configuraci&oacute;n.</p> <p class="rtejustify">Con tel&eacute;fono m&oacute;vil en mano, Draughon se dirigi&oacute; a la cubierta y su asistente Scott Evans se dirigi&oacute; a la sala de control para arrancar el motor diesel, para iniciar el proceso de calibraci&oacute;n del brazo de la draga.. Draughon configur&oacute; el amplificador desde la cubierta de la draga observando el comportamiento del brazo controlado por Scott.</p> <p class="rtejustify">Un gran reto al realizar los ajustes yace en el punto muerto. En la sala de control, Evans necesit&oacute; rotar el potenci&oacute;metro de control de velocidad casi a la mitad antes de que el brazo comenzara a moverse. En la cubierta, con el brazo a la vista y en comunicaci&oacute;n con Evans, Draughon pudo aumentar el output m&iacute;nimo, lo que permiti&oacute; una corriente m&aacute;s alta a un voltaje de comando m&aacute;s bajo, causando que el brazo se moviera justo al girar el potenci&oacute;metro. Debido a la r&aacute;pida configuraci&oacute;n y retroalimentaci&oacute;n, la tripulaci&oacute;n fue capaz de configurar la v&aacute;lvula con mayor precisi&oacute;n, m&aacute;s f&aacute;cilmente y en menor tiempo.</p> <p class="rtejustify"><strong>El Resultado</strong></p> <p class="rtejustify">Al tener un control remoto tipo wireless del amplificador, se obtiene un nivel de conveniencia y seguridad al configurar sistemas hidr&aacute;ulicos en lugares remotos. Nuevos usuarios pueden bajar la aplicaci&oacute;n AmpSet Blue app con su iOS o Android que ya tienen en su bolsillo, conectar con el amplificador e iniciar la configuraci&oacute;n en minutos.</p> <p class="rtejustify">Para la tripulaci&oacute;n a bordo de la draga en el Hillsboro Inlet, que pasa gran parte del tiempo en labores de mantenimiento del equipo en condiciones extremas de temperatura, humedad,&nbsp; y corrosi&oacute;n; es de gran beneficio el poder ajustar la velocidad del brazo de la draga r&aacute;pidamente y con precisi&oacute;n sin tener que bajar a la sala de m&aacute;quinas con tanta frecuencia.</p> <p class="rtejustify">Esta nueva combinaci&oacute;n de amplificador Bluetooth y aplicaci&oacute;n abre oportunidades en un rango amplio de aplicaciones tanto m&oacute;viles como industriales donde el costo, confiabilidad, facilidad de uso y seguridad son cr&iacute;ticas. Esto junto con la conformidad del equipo en cuanto a niveles de ruido y protecci&oacute;n ambiental robusta y tenemos una soluci&oacute;n para la gran mayor&iacute;a de aplicaciones electrohidr&aacute;ulicas.</p> <p class="rtejustify"><em>Art&iacute;culo originalmente escrito por Chad Lampton, ingeniero de producto en Sun Hydraulics Corp., Sarasota, FL.</em></p> <p class="rtejustify"><i style="color: rgb(51, 51, 51); font-family: Georgia, Times, &quot;Times New Roman&quot;, serif; font-size: 15px; line-height: 22.2px; text-align: justify;">Ricardo Sol&oacute;rzano&nbsp;se desempe&ntilde;a como Director General de EEM Technologies Corp., un proveedor de soluciones en Hidr&aacute;ulica, Neum&aacute;tica y Automatizaci&oacute;n Industrial para los mercados de Centro, Sur Am&eacute;rica y El Caribe.

En casos en que la bomba controle una operaci&oacute;n en la que su falla ponga en riesgo vidas humanas, como lo es el caso de aplicaciones militares, esta predictibilidad se hace a&uacute;n m&aacute;s cr&iacute;tica.</p> <p class="rtejustify">El sistema PumpMD utilizado para&nbsp;monitorear las condiciones del aceite en bombas de pistones axiales, permite conectividad por Wi-Fi para ser utilizado junto con la aplicaci&oacute;n m&oacute;vil de IoT (Internet of Things). Varios fabricantes ofrecen bombas de pistones axiales en las que las caracter&iacute;sticas dimensionales y de desempe&ntilde;o var&iacute;an. Debido a esto, el PumpMD es configurado de acuerdo a las especificaciones del cliente.</p> <p class="rtejustify">La &uacute;ltima versi&oacute;n del PumpMD permite la conectividad a WiFi para as&iacute; utilizarlo con la aplicaci&oacute;n m&oacute;vil, lo que le permite al usuario ver el estado actual o data hist&oacute;rica de una o m&aacute;s bombas, incluyendo el rango de eficiencia, tendencias y niveles de alarma. La aplicaci&oacute;n puede adem&aacute;s ser usada con otros dispositivos IoT, de manera que el equipo en planta o campo pueda ser monitoreado y controlado en conjunto.</p> <h3 class="rtejustify">Causas y Acci&oacute;n</h3> <p class="rtejustify">Luego que una bomba de pistones axiales es puesta en servicio, los pistones se van desgastando con el pasar del tiempo, lo que incrementa el flujo de drenaje o fuga interna. Las cabezas de los pistones se desgastan de acuerdo al nivel de contaminaci&oacute;n del aceite que es bombeado. A medida que aumenta el desgaste, aumenta el volumen de aceite que pasa a la carcasa, lo que hace que aumente la temperatura y presi&oacute;n&nbsp;en&nbsp;la misma (contrapresi&oacute;n causada por el incremento del flujo a trav&eacute;s del p&oacute;rtico de drenaje).</p> <p class="rtejustify"><a href="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/03/PumpMD-ALL-GREEN.jpg" target="_self"><img alt="" src="http://hydraulicspneumatics.com/site-files/hydraulicspneumatics.com/files/uploads/2015/03/PumpMD-ALL-GREEN.jpg" style="width: 300px; height: 205px; margin: 4px; float: right;" title="El dispositivo PumpMD monitorea el flujo de drenaje, temperatura y presión de unidades de pistones axiales.

Whether such an initiative would yield an acceptable return on the investment required, for the machines in question depends on a number of variables, which I don&#39;t have room to go into here. But this got me thinking about a bigger issue.<br /> <br /> The maintenance routines I teach in <a href="http://www.hydraulicsupermarket.com/books.html"><strong>my books and training programs</strong></a> are about equipping people with the knowledge the need today to optimize the reliability and service life of the hydraulic equipment they have right now. And that&#39;s fair enough - it&#39;s rarely helpful and not very instructive to tell someone what they should have done yesterday. With this is mind, one of the exercises we do during the seminar is carry out a maintenance and reliability audit on an existing hydraulic machine.<br /> <br /> Even though equipment design and equipment maintenance are often viewed in isolation, the reality is, certain aspects of hydraulic machine design have a significant impact on the machine&#39;s operating cost and reliability, and ultimately, its life-of-ownership cost.<br /> <br /> Over lunch, the same maintenance manager mentioned that his mine is starting to think about the replacement of their aging fleet of hydraulic shovels. And it occurred to me, the best time to carry out a maintenance and reliability audit on a piece of hydraulic equipment is BEFORE you buy it.<br /> <br /> By starting with the end in mind, you get the maintenance and reliability outcomes you desire - before the machine even gets delivered. For example:<br /> <br /> You specify the contamination control targets you want to achieve based on your reliability objectives for the piece of equipment. And instruct the manufacturer to deliver the machine appropriately equipped to achieve these targets.<br /> <br /> Based on the weight and viscosity index of the hydraulic oil you plan to use, you determine the minimum viscosity and therefore the maximum temperature you want the machine to operate at. And instruct the manufacturer to deliver the machine equipped with the necessary cooling capacity, based on ambient temperatures at your location. Rather than accepting hydraulic system operating temperatures dictated by the machine&#39;s &#39;design&#39; cooling capacity - as is the norm.<br /> <br /> And if you don&#39;t think oil viscosity/temperature is this important - you&#39;re mistaken. Lubrication failure resulting from low oil viscosity is one of the biggest causes of premature failure in hydraulic components. If you&#39;re not on top of this issue it could be costing you big.<br /> <br /> And we could continue by specifying things like flooded inlet for all pumps and so on. But you get the idea.<br /> <br /> So the next time you or the company you work for are looking to acquire hydraulic equipment, begin with the end in mind. Define your maintenance and reliability objectives in advance and make them an integral part of your equipment selection process. Failing to do so could be a costly mistake in the long run.

The patented, parallel hydraulic hybrid system applies a hydraulic system to the driveline of a vehicle to regenerate braking energy. Hydraulic pumps and a lightweight accumulator brake the vehicle, store the braking energy, and then use that stored energy to provide power to the wheels. As a result, it burns less fuel and cuts emissions. Additional benefits include safer braking, more power for acceleration, and a decrease in greenhouse gas emissions.</p> <p>The ERS does not have batteries. Instead it safely and efficiently stores energy in composite hydraulic accumulators, which are a fraction of the cost and weight of batteries. The ERS can be installed on new vehicles and retrofitted on vehicles already in service. It is sold through a network of dealers and upfitters.

Mainly, we publish the only monthly magazine that is 100% devoted to fluid power technology and circulated to an audience of audited, qualified fluid power engineers, technicians, mechanics, and other technical people.</p> <p>But it goes deeper than that. There are other important distinguishing characteristics of H&amp;P. We cover the total market for fluid power technology, meaning that we report on original equipment manufacturers&#39; (OEM) products and techniques, but we also cover maintenance, repair, and other aftermarket best practices and products. While many products are sold by fluid power component manufacturers directly to OEMs, a large segment of fluid power component sales involves the supply channel and the end use aftermarket.</p> <p>Both areas have their specialists. Consider the architect of a home, who conceives a design, plans it carefully, and conveys that plan to the builders. The building professionals carry out the design plan of the architect to bring the home to reality. They use building materials and procedures to construct the home the best they can. This is the equivalent to the design engineer and OEM.</p> <p>Now consider all the maintenance, repair, and remodeling of a home that takes place in the years and decades after it is built. Consider all the materials, contractors, and procedures that are used to beautify homes over time. This set of goods and services is comparable to the fluid power aftermarket.</p> <p>In both cases &mdash; homes and fluid power systems &mdash; the OEM and the aftermarket specialists have certain skills and use certain products to get the job done. While one set of individuals makes the end product (home or machine) happen, the other set of specialists not only maintains the end use product, but regularly seeks to make improvements to keep things up to date.</p> <p>We at <em>Hydraulics &amp; Pneumatics</em> regularly report on the products and procedures that build the very best mobile and industrial machines. We also produce articles and application stories that tell our audience about products and practices that maintain and improve mobile and industrial machinery across all markets. This formula has worked for us and our readers since 1948 and we are confident that our content has not only stayed current with technology but is often on the cutting edge.</p> </div> Other Technologies Mon, 12 Sep 2016 16:00:00 +0000 5142 at http://hydraulicspneumatics.com Controlling Pressure Conserves Energy http://hydraulicspneumatics.com/controls-instrumentation/controlling-pressure-conserves-energy <div class="field-deck"> Specifying an air regulator helps make a pneumatic system run smoothly.

When selecting a pressure regulator, consider the maximum inlet pressure, type of adjustment, reduced secondary pressure, and accuracy.</p> <p>Most pressure-control regulators feature either a piston or diaphragm control construction and a balanced poppet. Piston regulators are more durable and robust, but are not quite as efficient at holding and maintaining a set downstream pressure. Diaphragm regulators are the most common style and maintain a set pressure within the limits required of most industrial applications.</p> <div class="related-content"> <div class="related-label">Related</div> <p><a href="http://hydraulicspneumatics.com/200/TechZone/AirFiltersandFR/Article/False/6457/TechZone-AirFiltersandFR">Engineering Essentials: Air Regulators</a></p> <p><a href="http://hydraulicspneumatics.com/controls-instrumentation/pressure-regulators-come-two-versions">Pressure Regulators Come in Two Versions</a></p> <p><a href="http://hydraulicspneumatics.com/other-components/high-pressure-pneumatic-regulators">High-Pressure Pneumatic Regulators</a></p> </div> <p>A third style is available as well, featuring a rolling diaphragm, which can give the long service life of a piston-style unit with the accuracy of the diaphragm units. This design is often used in precision regulators, where compressed air pressure must be precisely controlled for process applications rather than for fluid power.</p> <p>After establishing the maximum flow, inlet pressure, and secondary pressure required, select the correct regulator based on manufacturers&rsquo; performance curves. Note the inlet pressure on which curves are derived because different manufacturers may use different inlet pressures. Many manufacturers have attempted to provide performance curves on an inlet pressure of 100 psi, with set secondary pressures of 90, 75, 60, 45, and 30 psi to make it easier to compare and select products.</p> <p><strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/HP0507-regulator.gif" style="width: 595px; height: 449px;" title="Illustrations show interior design of regulators: manual-operated, left, and pilot-operated, right." /></strong></p> <p><strong>Spring into Action</strong></p> <p>Next, determine the regulator&rsquo;s adjustment spring range. Regulators come with various spring ranges to offer the user better adjustment and control of the secondary set pressures. A common misconception is that a 60-lb spring can be considered a pressure limiter and will only give a 60 psi output. This is not true, as a 60-lb spring can supply an adjusted pressure of well over 60 psi. A regulator&rsquo;s pressure-control spring is not a pressure limiter.</p> <p>When selecting a spring range, choose a control spring that will place the desired set pressure as close as possible to the middle of the control spring&rsquo;s range. This gives the maximum amount of adjustability and control.</p> <p><strong>Elements of Style</strong></p> <p>The next choice is to select an adjustment style: manual or pilot-operated, as shown in the illustrations. Manually operated units use a control knob or T-handle to adjust the regulator&rsquo;s output pressure. The non-rising control knob is the most common style used today because of its compact size and styling. The T-handle version is the more traditional style and is more commonly found on heavy-duty equipment.</p> <p>A pilot-operated regulator simply replaces the standard control knob and spring with a pilot chamber. A small external regulator supplies a control pressure to the pilot chamber. Because most pilot-operated regulators have a 1:1 ratio of pilot pressure to output pressure, a pilot pressure of 100 psi would deliver 100 psi out of the main regulator.</p> <p>A standard industrial pressure regulator will have an accuracy of 2 to 4 psi, and if more accurate pressure control is needed, a more precise-design regulator&mdash;such as a rolling diaphragm&mdash;should be selected. Precision regulators use single- or double-diaphragm chambers and reduced poppet areas to improve performance. Precision regulators typically also have a constant relief bleed to improve the regulator&rsquo;s ability to relieve excess pressure. It also makes it more accurate, with an accuracy of within 0.05 to 0.5 psi.</p> <p><strong>Spend Money to Save Money</strong></p> <p>In general, if you reduce a system&rsquo;s operating pressure by 2 psig, you can save 1% in overall operating cost. This savings can start at the point of use by revisiting your existing applications to reevaluate required pressures with the intent of reducing them.</p> <p>One of the most common applications where you can realize savings is a standard air cylinder moving a load into position and then resetting itself. Common practice is to operate cylinders at the same pressure for extension <em>and </em>retraction. However, by applying a <em>dual-pressure </em>technique, you save energy by using high pressure only where it is needed.</p> <p>For example, if high force is needed only for the cylinder extension (push stroke), a dual-pressure regulator can be installed in the line connecting the directional valve to the cylinder&rsquo;s rod-end port. This configuration will route full pressure to the cap end of the cylinder for extension, but apply a reduced pressure at the rod-end port for retraction. Installing a $50 regulator might save nearly $300 per year.</p> <p>Not all regulators are capable of this function. Regulators with a piston or a rolling-diaphragm construction tend to perform best because of their long life. However, a common flat-diaphragm regulator (which is susceptible to rupturing from repeated stress) can be used by installing a bypass check valve in parallel to route exhaust flow past the regulator.</p> <p><strong>Combined Functions</strong></p> <p>Manufacturers frequently pre-assemble filters and regulators to form combination units. They&rsquo;re packaged together as common body sizes with common connection port sizes. Modular connections also ease conversion between metric and inch port types. Interconnections may be via threaded nipples or modular face connectors. Modular connectors facilitate component removal for servicing or cleaning. In addition, some manufacturers combine filters and regulators in stacked assemblies where the filter head becomes the regulator body. The components share common inlet and outlet connections, which makes the assembly very compact.</p> <p><strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/Automation-Direct-Nitra-regulator.jpg" style="width: 595px; height: 203px;" title="This filter-regulator combination not only combines two functions into a single component, but also provides dramatic space savings over its modular counterparts. (Image courtesy of AutomationDirect)" /></strong></p> <p>Such packaged units are practical choices for most industrial applications. The selection criteria are the same as with any of the individual components, except that the combined pressure and flow performance becomes the only consideration. When critical requirements dictate the use of specialty filters or precision regulators, the assembly probably must be made up of individual selections and connected with pipe nipples.</p> <p><a href="http://sourceesb.com" target="_blank"><img alt="" src="/site-files/globalpurchasing.com/files/uploads/2016/07/15/SourceESB_Lookin_For_Parts_Banner.jpg" style="width: 600px; height: 46px;" /></a></p> </div> http://hydraulicspneumatics.com/controls-instrumentation/controlling-pressure-conserves-energy#comments Controls & Instrumentation Cylinders & Actuators Other Components Fri, 09 Sep 2016 16:16:00 +0000 40031 at http://hydraulicspneumatics.com U.S. Construction-Equipment Exports Continue to Drop First Quarter, 2016 http://hydraulicspneumatics.com/news/us-construction-equipment-exports-continue-drop-first-quarter-2016 <div class="node-body article-body"><p>A&nbsp;<a href="https://www.aem.org/market-data/market-intelligence-international/global-markets-international-trade-reports/" target="_blank">midyear report</a>&nbsp;from the&nbsp;<a href="https://www.aem.org/" target="_blank">Association of Equipment Manufacturers</a>&nbsp;(AEM)&nbsp;shows that&nbsp;global sales of&nbsp;U.S.-made&nbsp;construction equipment continue to drop, despite overall growth in the global&nbsp;construction market.&nbsp;Business Monitor International predicts that the global construction industry will grow 3.4% in 2016, but roughly half of that growth is expected to be from sales within the North American market.&nbsp;</p> <p>The AEM report shows that first quarter 2016 exports of U.S. equipment were down 24% compared to first quarter sales in&nbsp;2015.&nbsp;With a total $2.7-billion of U.S.-made equipment shipped to global markets, the 2016 midyear sales mark the 13<sup>th</sup>&nbsp;quarter in which year-over-year&nbsp;U.S.&nbsp;exports continue&nbsp;to decrease.</p> <div class="related-content"> <div class="related-label">Related</div> <p><a href="http://hydraulicspneumatics.com/rail-truck-bus/more-hydraulic-hybrids-horizon">More Hydraulic Hybrids on the Horizon</a></p> <p><a href="http://hydraulicspneumatics.com/blog/sweet-spot-hydraulic-hybrids">The Sweet Spot for Hydraulic Hybrids</a></p> <p><a href="http://hydraulicspneumatics.com/hydraulic-pumps-motors/hybrid-drive-transmission-surpasses-epa-standards">Hybrid-Drive Transmission Surpasses EPA Standards</a></p> </div> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2016/09/09/Exports%20of%20U.S.-MadeConstruction%20Equipment%20Mid2016.png" style="margin: 3px; font-size: 12.8px; width: 350px; height: 560px; float: left;" /></p> <p>The report cites data from the&nbsp;Department of Commerce to measure U.S. exports by dollar volume for seven world regions (<em>fig. 1.)&nbsp;</em>&nbsp;Europe was the only region to increase purchases of construction equipment from the U.S. (by 5%).

These were:</p> <ol> <li>Canada - $1.1 billion, down 28%</li> <li>Mexico - $310 million, down 0.01%</li> <li>Australia - $148 million, down 10%</li> <li>Belgium - $101 million,&nbsp;<strong>up</strong>&nbsp;38%</li> <li>Peru - $85 million, down 17%</li> <li>Germany - $74 million,&nbsp;<strong>up</strong>&nbsp;58%</li> <li>Chile - $60 million, down 48%</li> <li>China - $49 million, down 31%</li> <li>United Kingdom - $47 million,&nbsp;<strong>up</strong>&nbsp;8%</li> <li>South Africa - $40 million, down 65%</li> </ol> <p>In addition to increasing its purchase of U.S. construction equipment by 38%, Belgium ranked as the fourth highest importer of U.S. equipment, perhaps because its Port of Antwerp serves as a pass-through for the European continent. Growth in Germany is accredited to a boost in excavators and wheel loader exports, while increased exports to the UK appear to be driven by an increase in self-propelled aerial work platforms.</p> <p>AEM also released reports for U.S. agriculture equipment.&nbsp;<a href="https://www.aem.org/market-data/market-intelligence-international/global-markets-international-trade-reports/">Both global-market reports are available for&nbsp;download by&nbsp;members</a>.&nbsp;</p> </div> http://hydraulicspneumatics.com/news/us-construction-equipment-exports-continue-drop-first-quarter-2016#comments Agricultural Construction News Fri, 09 Sep 2016 15:46:00 +0000 40051 at http://hydraulicspneumatics.com Courtesy of Raken App Troubleshooting Challenge: Fix One Problem, Another Crops Up http://hydraulicspneumatics.com/controls-instrumentation/troubleshooting-challenge-fix-one-problem-another-crops <div class="node-body article-body"><p>A foundry had a sand mold squeezing press that was overheating, so company officials called on <a href="http://turnerhydraulics.com/" target="_blank">Turner Hydraulics</a>, Carlisle, Pa., to troubleshoot the problem.

Once that occurred, the pump would re-engage and build the pressure back up to 1,000 psi.</p> <p>The technician reprogrammed the PLC back to its original program, and subsequently found that the accumulator&rsquo;s bladder had failed. This was probably the reason someone changed the program&mdash;to compensate for pressure problems and not realizing the real problem was a ruptured accumulator bladder.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/0916_Troubleshooting_Fig_web.jpg" style="width: 595px; height: 832px;" /></p> <p>After the technician replaced the accumulator bladder, he started the machine, and all of the functions ran fine except for two of the squeeze feet cylinders. They would not extend, and when they retracted, a gauge did not show any pressure.</p> <p>The remote-control pressure reliefs for the reducing valve were located about 3 ft. from the main valve, and the &frac12;-in. gauge line ran over to the operator station, where the defective gauge was located. The reducing valve was disassembled, and its control orifice was found to be open. Everything inspected should have worked. The pump would go to the 1,000-psi relief setting and then unload.</p> <p>The original problem of overheating was caused by the pump running constantly instead of having the accumulator supply holding pressure.

When we checked the valve positions in the stack, we found that someone had confused the pressure-reducing valve for the relief valve. The pressure-reducing valve closed, tending to limit its output pressure to 500 psi. However, a pressure-reducing valve does not respond to incoming pressure like that of a relief valve. Consequently, the pressure-reducing valve isolated the pump relief valve from limiting the pump&rsquo;s output pressure.</p> <p>Fortunately, the weak point for this system was the power rating of the system. If mechanics would have installed another larger electric motor, something else in the hydraulic system might have ruptured before the electric-motor overload tripped, causing a serious safety problem.</p> <p><a href="/site-files/globalpurchasing.com/files/uploads/2016/07/15/SourceESB_Lookin_For_Parts_Banner.jpg" target="_blank"><img alt="" src="/site-files/globalpurchasing.com/files/uploads/2016/07/15/SourceESB_Lookin_For_Parts_Banner.jpg" style="width: 600px; height: 46px;" /></a></p> </div> http://hydraulicspneumatics.com/controls-instrumentation/troubleshooting-challenge-fix-one-problem-another-crops#comments Accumulators Controls & Instrumentation Hydraulic Pumps & Motors Hydraulic Valves Fri, 09 Sep 2016 15:36:00 +0000 40021 at http://hydraulicspneumatics.com Achieve Flexible, Precise Control of up to 32 Motion Axes http://hydraulicspneumatics.com/controls-instrumentation/achieve-flexible-precise-control-32-motion-axes <div class="node-body article-body"><table border="0" cellpadding="0" cellspacing="0" width="570"> <tbody> <tr> <td width="41"><img src="http://insidepenton.com/electronic_design/adobe-pdf-logo-tiny.png" /></td> <td style="padding-left: 0px;" width="459"><a href="/controls-instrumentation/achieve-flexible-precise-control-32-motion-axes">Download this article as a .PDF file.</a><br /> This file type includes high-resolution graphics and schematics when applicable.</td> </tr> </tbody> </table> <p><a href="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/Delta-RMC200.jpg"><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/Delta-RMC200.jpg" style="width: 300px; height: 205px; float: right; margin-left: 4px; margin-right: 4px;" title="Delta Computer Systems’ new RMC200 motion controller can perform closed-loop control of up to 32 axes simultaneously." /></a>Machine designers and system integrators are always looking for ways to make machines and sophisticated test systems more productive.

Concepts of pressure, force, flow, and torque are second nature. But the continuing influx of electronic components&mdash;especially transducers&mdash;into hydraulic and pneumatic systems makes knowledge of electrical terminology and concepts essential to job performance.</p> <p>Pressure transducers serve the same function as a pressure gauge&mdash;the difference being that the gauge offers a visual indication of pressure whereas a transducer provides an electrical signal indicative of pressure. (Some pressure transducers have a digital readout to also provide visual indication.) To help explain some of the most common concerns surrounding pressure sensors, direct answers are given to the following frequently asked questions:</p> <p><strong>Is there a difference between a pressure transducer and a pressure transmitter? </strong></p> <p>When these terms originated, a distinct difference existed between the two. A transmitter was referred to as an instrument with a current signal, such as 4 to 20 mA, whereas a transducer had a voltage signal ranging from 0 to 10 V dc. Over time, these terms have become interchangeable. So in general, no, there is no difference, but the answer may depend on whom you talk to.</p> <div class="related-content"> <div class="related-label">Related</div> <p><a href="http://hydraulicspneumatics.com/controls-instrumentation/today-s-versatile-transducers-step-performance">Today&rsquo;s Versatile Transducers Step Up Performance</a></p> <p><a href="http://hydraulicspneumatics.com/controls-instrumentation/wireless-bluetooth-pressure-transducer">Wireless Bluetooth Pressure Transducer</a></p> <p><a href="http://hydraulicspneumatics.com/controls-instrumentation/sensing-decisions-under-pressure">Sensing Decisions Under Pressure</a></p> </div> <p><strong>One problem with pressure transducers is that they normally don&rsquo;t show you pressure. Is there a way to see what the pressure is without having to install a new indicating transducer? </strong></p> <p>Of course, <a href="http://sourceesb.com/manufacturers/search?q=noshok" target="_blank">Noshok</a> and other manufacturers offer transducers with an LED indicator to display pressure right on the transducer. But for existing applications, Noshok&rsquo;s 1800 series digital indicator can easily be installed between a transducer&rsquo;s DIN 43650A output connector and cable. In fact, it can work with any brand transducer with a DIN 43650A connector and sufficient power-supply voltage to drive all instruments in the loop.</p> <p>Another advantage is that it can be transferred from one transducer to another. Therefore, if a transducer becomes damaged, the indicator can be reused on a new transducer, provided it also has the DIN 43650A connector.</p> <p><strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/Noshok-1800_0.jpg" style="width: 300px; height: 189px; float: right;" title="The 1800 Series attachable loop-powered digital indicator provides local readout from sensors with 4- to 20-mA output and a DIN 43650A connector." />What determines a pressure transducer&rsquo;s accuracy? </strong></p> <p>Pressure transducers are mechanical structures, so they respond not only to changes in pressure, but also to changes in temperatures. Extreme temperature fluctuations may change a transducer&rsquo;s output signal even though pressure remains constant.</p> <p>Accuracy of a pressure transducer generally takes into account nonlinearity, hysteresis, and non-repeatability. Nonlinearity is the maximum deviation from the average characteristic line to the reference line. Hysteresis is the maximum difference between the characteristic lines recorded at increasing and decreasing pressure. Non-repeatability is the maximum deviation between values of output for any single input of multiple cycles, considering decreasing and increasing pressures separately.</p> <p><strong>Because temperature has such a major impact on transducer accuracy, can I use a pigtail siphon to help keep hot hydraulic fluid from affecting the transducer? </strong></p> <p>Sure. Pigtail siphons are typically used in steam applications, but they can also be used in systems where hydraulic systems may run hot. The pigtail helps cool the hot fluid before it reaches the transducer, and can help dissipate fluid shock.</p> <p><strong>What are RFI, EMI, and ESD, and why are they important? </strong></p> <p>Radio-frequency interference (RFI) and electromagnetic interference (EMI) are types of electrical noise, or interference. RFI frequently comes from two-way radios, while EMI often is generated by ac electric motors. Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects when they touch each other. CE-compliant devices incorporate protection techniques and components to minimize most of these types of interference.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2015/03/0916_PressureSensors_figures.gif" style="width: 595px; height: 318px;" title="Accuracy (left) is a combination of characteristics, such as hysteresis (left), nonlinearity (right), non-repeatability, and effects from temperature. In both diagrams, the Ideal line represents linear output of a perfect transducer." /></p> <p><strong>Can orifices and snubbers be used with pressure transducers? </strong></p> <p>As with other pressure measurement instruments, including gauges, pressure pulsations and spikes may become problematic for pressure transducers. Measuring the pressure of an incompressible fluid introduces the possibility for pulsations and spikes, which can damage pressure transducers. A factory-installed orifice in the pressure connection can protect the transmitter from damage. Although this solution is usually adequate, if there&rsquo;s potential for the orifice to become clogged by dirt in especially dirty hydraulic fluid, we recommend installing a piston snubber.</p> <p><strong>What is the difference between proof pressure and burst pressure? </strong></p> <p>Proof pressure, which scales higher than the full-scale pressure point, is the maximum pressure the transducer can withstand without affecting its performance and calibration.

This single-stage cylinder was 6&quot; bore x 3&quot; rod x 14&#39; stroke. The OEM was in a terrible position because they had 80 machines that could not ship by the end of the month deadline due to the squealing - which could be heard blocks away. The OEM was demanding that the cylinder manufacturer send a crew of men to change out all 80 cylinders!</p> <p>But what could the problem be? Seal stick and slip? Excessive stroke speed? Internal leakage? Load-control valve? What else? How would you approach this situation?</p> <p>Well, the outcome of this story, as told by Doug Lien, founder and former owner of Cylinder City Inc. is as follows:</p> <p>&quot;The squeal was present at all engine speeds - so flow rate / stroke speed was not an issue. Through a process of elimination, I isolated or changed out all cylinder valves. No difference.</p> <p>I then removed the cylinder from a machine and placed it on a bench. I connected the cylinder to the same new machine with quick disconnects. I removed the rod seal and under no load I stroked the cylinder and it still squealed. I then removed the piston seal and the squeal remained. So it continued to squeal with no seals installed.</p> <p>I reinstalled the seals and connected the cylinder to an older machine, which was referred to as the &quot;yard machine&quot;, while the cylinder was still on the bench. The squeal was gone! I drained the oil from the cylinder and reconnected it to the new machine -- the squeal was back! This eliminated the cylinder.</p> <p>The General Manager at the OEM was still insisting that I contact my factory and get a crew of men to his plant and change out all 80 cylinders. By now though I was confident that the cylinders were not the cause of the problem. I asked him to give me another day in order to determine the root cause.</p> <p>Earlier that day I noticed two things that put me on the right trail. One was the color of the oil that was draining from the cylinder when I disassembled it. The oil looked like ivory soap. The other was a slight hissing sound when I removed the head gland from the cylinder. I knew at this point that aeration was causing the squeal.</p> <p>But the challenge was trying to convince the customer&#39;s engineers. I had to prove where the air was coming from and why. So the big question was: What was different about the new model machine? Were the pumps changed? Was the design of the hydraulic tank changed in any way? How about the suction lines or suction strainer? The answer to all these questions was the same: NO.</p> <p>When I had connected the cylinder to the new machine the cylinder squealed, when I connected it to the older machine it was quiet. When switching the cylinder from new machine to old machine I had made sure that the cylinder was completely drained of hydraulic fluid.</p> <p>So now back to the questions. Have you changed oil viscosity, brand, supplier or formula? Again the answer was NO. I insisted that the oil was the source of air in the system and that air was causing the squeal. The oil vendor was called and he stated that to the best of his knowledge the oil was the same. I insisted that the oil vendor contact the blender to ask if the additive package had been changed. They agreed and the next morning a chemist from the oil blender was on site.</p> <p>In the meantime I went to the nearest CAT dealer and got some of CAT&#39;s Anti-Chatter hydraulic oil additive. I added a quart to a machine that was squealing and within 5 minutes the squeal was gone.</p> <p>Needless to say at this point all eyes turned to the oil blender and their chemist. It turned out that the formula of the oil had been changed and the amount of air-release additive had been reduced. All 80 machines had the hydraulic fluid replaced and their shipment to customers was back on schedule.&quot;</p> <p>As this story shows, not following proven troubleshooting PRINCIPLES can result in the costly change-out of the WRONG components.

This entails improving efficiency and productivity without compromising safety, and minimizing operational breakdowns for altogether more cost-efficient operations. However, problems are arising due to inadequate performances from components that are manufactured from conventional engineering steels (such as plain carbon steel), often resulting in costly and disruptive equipment failures.</p> <p><img alt="Fig. 1" src="/site-files/hydraulicspneumatics.com/files/uploads/2016/09/02/Mining-fig-1.gif" style="width: 595px; height: 347px;" title="1. These are the principle parameters in hydraulic piston-rod design." /></p> <h3>Piston Rods in Hydraulic Cylinders</h3> <p>Hydraulic piston rods are a case in point where conventional steels are performing inadequately. These instances have resulted in oil leaks or pressure loss, or else have necessitated regular and disruptive cylinder changes. Analysis has determined that these failures are caused by cyclic stresses, which are typical in demanding mining and construction applications, and to which piston rods are commonly exposed over long periods. The challenge for OEMs: How can the costs attached to the piston rods be reduced in spite of these problems?</p> <p>The main driver of cost and capital in piston rods in hydraulic cylinders is the diameter of the bar. Costs of the material, handling, and cutting increase in concert with the weight of the bar. Meanwhile, the cost of surface operations&mdash;machining, grinding, chrome plating, and so on&mdash;increase with the surface area. The cost of a rod increases exponentially with the diameter as a result.</p> <p>As a general rule, the cost of a piston rod decreases by 15% by reducing its diameter by 5 mm. Other effects are lighter weight and reduced space requirements, which could also translate into lower energy consumption and greater versatility in design.</p> <p>But to achieve these benefits, the rod material must be strong enough to maintain equal strength at the smaller diameter. Therefore, a key parameter in hydraulic piston-rod design is dimensioning against fatigue, buckling, and impact failure <em>(Fig. 1)</em>.</p> <h3>Fatigue Research</h3> <p>For decades, Ovako Steel has conducted comprehensive research in fatigue behavior and failure, and built an extensive database of detailed performance data. The risk of buckling in piston rods depends on the yield strength, the elastic modulus of the material, and the geometry of the rod, as defined by the slenderness ratio. European Convention for structural steelwork (ECCS) and American Institute of Steel Construction (AISC) recommendations define the buckling stress as a function of slenderness ratio (&lambda;):</p> <p>&lambda; = 4L / d</p> <p>Generally speaking, the buckling stress at small slenderness ratios corresponds to the yield stress of the material and decreases with increasing slenderness ratio to the extreme case, where it becomes independent of yield strength.</p> <p>In practice, 70 to 80% of all hydraulic cylinders are designed with low or moderate slenderness ratios (below 100). That means the yield stress of the material has an important influence in defining the required diameter of the rod for cylinders operating in conditions where there is risk of buckling.</p> <p>However, a piston rod in many instances operates in a dynamic environment with push-pull forces, and in which it will be susceptible to fatigue. Each rod has a unique fatigue limit, and dimensioning is made on the basis of experience, or else through fatigue testing of finished piston rods or cylinders.</p> <p>All other things being equal, fatigue strength increases with the tensile strength of the rod material. Because the main cost driver is the diameter of the rod, it follows that the strength of the rod material is the main lever to reduce cost by dimensioning the rod against fatigue <em>(Fig. 2)</em>. Compared to the most commonly used material for hydraulic cylinder rods, C45E, Ovako has measured that the cost-reduction potential achieved through the use of stronger materials is on the order of 20 to 30%.</p> <p><img alt="Fig. 2" src="/site-files/hydraulicspneumatics.com/files/uploads/2016/09/02/Mining-fig-2.gif" style="width: 595px; height: 272px;" title="2. This displays dimensioning of a piston rod against fatigue." /></p> <p>Nevertheless, not all high-strength steels are suitable for piston rods due to problems deriving from the inherent impact of slag inclusions, which intersect the surface and create segregation at the center of the rod. Indeed, it is not unusual that chemical compositions aimed at promoting strength or machinability can end up being the cause of problems in welding, and in friction welding in particular. Moreover, certain slag inclusions at the surface of the material will dissolve during the chrome plating process, giving rise to porosity, which can translate to weakness in the chrome layer.</p> <p>The true cost effect of different steel materials for a piston rod is complicated to assess. However, a simple approach could be to first select several grades with sufficient impact toughness and suitable machinability/welding characteristics, and then choose the one which offers the lowest price per unit of yield strength.</p> <p>Cromax is a line of chrome-plated and nickel-chrome-plated bars and tubes primarily used as piston rods in hydraulic cylinders. These steels have been developed specifically for the manufacture of piston rods in hydraulic cylinders. They can be thought of as &ldquo;piston rod steels,&rdquo; in much the same way that steels developed specifically for ball and roller bearing applications are referred to as bearing steels.</p> <h3>Plating with Nickel-Chrome</h3> <p>Steering systems, suspension systems in vehicle cabins, and the tilting mechanisms in forklifts typically have one critical component in common: hydraulic cylinders. These cylinders and the hydraulic systems they support have long been taken for granted. But without their ability to withstand corrosion, dynamic loads, and constant wear-and-tear over many years, these components and the piston rods that drive them would be subject to frequent failure.</p> <p>Plating with chromium is by far the most common surface treatment for piston rods. Nevertheless, chromium has poor ductility and all chrome-plated layers have micro cracks, which can let the external environment penetrate the layer and cause corrosion. This can be rather swift in corrosive environments or safety-critical mining and construction applications, where the rod is exposed to mechanical damage. The chromium can be combined with an underlying layer of nickel, which dramatically improves corrosion resistance <em>(Fig. 3)</em>.</p> <p><img alt="Fig. 3" src="/site-files/hydraulicspneumatics.com/files/uploads/2016/09/02/Miningfig3.gif" style="width: 549px; height: 309px;" title="3. Standard chrome plating is shown here alongside nickel-chrome plating, illustrating the benefits of the latter." /></p> <p>Due to its high ductility, the nickel-chrome layer is able to maintain its corrosion properties in the field, including in aggressive mining and construction environments. Random testing is also vital to maintaining the performance of the hydraulic cylinders&mdash;e.g., the compression and corrosion testing <em>(Fig. 4)</em>.</p> <p>To protect rods from damage in the event of external impact, induction hardening of hydraulic cylinder piston rods has proven beneficial in demanding mining and quarrying applications. Induction hardening can also improve the mechanical properties of the rod&mdash;especially resistance to buckling failure in push mode. Relative to a non-hardened rod with the same steel base, the diameter of an induction-hardened rod can also be downsized for reduced weight and lower costs.</p> <p>A further significant lever to reduce the cost of the piston rod is to minimize the thickness of the chrome or nickel-chrome layers. In safety-critical applications where the component is exposed to risk of mechanical damage, cylinder manufacturers should select the thinnest combination of chrome and nickel to provide sufficient corrosion protection after multiple compressions.</p> <p><img alt="Fig. 4" src="/site-files/hydraulicspneumatics.com/files/uploads/2016/09/02/Mining-fig4.gif" style="width: 595px; height: 270px;" title="4. Depicted is a chromed bar and nickel-chromed bar after compression and corrosion testing." /></p> <h3>Quality Through Cleanliness</h3> <p>Quality is among the main demands that customers place on Ovako steels. The quality of steel pertains specifically to its cleanliness, or the presence within the metallurgy of defects such as non-metallic inclusions&mdash;foreign substances produced by chemical reactions during melting and pouring processes that disrupt the steel&rsquo;s structural homogeneity.</p> <p>Non-metallic inclusions are shown to create cracks and fatigue failures in steels. These cause many conventional steels to fail when subjected to the non-steady, continuously varying loads and cyclic stresses that occur in demanding mining applications. Based on analysis of thousands of fatigue failures with scanning electron microscope (SEM) technology, Ovako engineers are able to demonstrate how the quality of steels significantly impacts the fatigue life of components.</p> <p>Poor performance typically arises with conventional steels because they are anisotropic, or directionally dependent, by nature. Inclusions become deformed or elongate within the steel during the rolling stage, so its fatigue strength will be higher when loaded parallel to the rolling direction than if it is loaded transverse to the rolling direction.</p> <p><em>Per Israelsson is head of marketing &amp; technology, <a href="http://www.ovako.com" target="_blank">Ovako Cromax Group</a>, Ovako AB, Stockholm, Sweden.</em></p> <p><a href="http://sourceesb.com" target="_blank"><img alt="" src="/site-files/globalpurchasing.com/files/uploads/2016/07/15/SourceESB_Lookin_For_Parts_Banner.jpg" style="width: 600px; height: 46px;" /></a></p> <table border="0" cellpadding="0" cellspacing="0" width="570"> <tbody> <tr> <td width="41"><img src="http://insidepenton.com/electronic_design/adobe-pdf-logo-tiny.png" /></td> <td style="padding-left: 0px;" width="459"><a href="/datasheet/better-steels-make-better-cylinders-pdf-download">Download this article in .PDF format</a><br /> This file type includes high resolution graphics and schematics when applicable.</td> </tr> </tbody> </table> </div> http://hydraulicspneumatics.com/cylinders-actuators/better-steels-make-better-cylinders#comments Cylinders & Actuators Mining Fri, 02 Sep 2016 15:04:00 +0000 39901 at http://hydraulicspneumatics.com Better Steels Make Better Cylinders (.PDF Download) http://hydraulicspneumatics.com/datasheet/better-steels-make-better-cylinders-pdf-download <div class="node-body datasheet-body"><p>Innovation will prove key to survival for those in the mining industry&mdash;a necessity driven by growing competition from original equipment manufacturers (OEMs) in the Far East as they race to bring their products in line with the standards set by Western counterparts.

Instead, system integrators buy the components that experts have designed to build the system that perfectly fits their customers&rsquo; needs.</p> <p>Still, as the adoption of embedded-system technology continues to grow, new questions arise for OEMs integrating systems on behalf of their customers. In particular, what are those functional, economic, and complexity tipping points where it starts to make sense to pursue the newer, promising control schema of distributing controls? Thus, four primary questions must be answered by anyone weighing the merits of decentralized controls for mobile applications.</p> <p><strong>Questions About Distributed Control</strong></p> <p><strong>How complex is my application?</strong></p> <p>A simple application is perfect for central control. A one-operation application will likely not tax a central controller. Physical distances may be small, and communication bandwidth is not a concern these types of applications.</p> <p>A complex application, however, running fast with many simultaneous commands and operations, may affect control priorities and a central controller&rsquo;s response time. These more complex applications typically work at higher speeds and require much feedback, resulting in higher productivity and more precise control. And while systems that exchange real-time data between subsystems may be good candidates for use with a central controller, not every application is the same:</p> <p>&bull; Applications requiring asynchronous control may work well with distributed control, e.g., feedback loops that need higher frequency sampling than other loops. When different tasks are required at different intervals, distributed control might be the answer.</p> <p>&bull; Subsystems that have limited interaction with the higher-level system, such as when performing closed-loop control on a valve spool or pump swash plate, may be good candidates for distributed control.</p> <p>Judging exactly when a controller will be taxed too heavily may be more art than science, but certainly an increasing number of parts will affect machine speed and, ultimately, the operations to be performed by the application. One starting place for phasing out complexity versus simplicity is to ask about the high-level requirements.</p> <p>Physical size (of the machine) may be another indicator of complexity:</p> <p>&bull; Putting the embedded system closer to the operation/actuation point quickens response times. There is less need for the central controller to be sorting smaller operations because the embedded system handles that task.</p> <p>&bull; Putting the embedded system closer to the operation/actuation-point brings down manufacturing and service costs because less dedicated wiring is needed to enable communication with the central controller.</p> <p>In fact, physical size raises a few more questions.</p> <p><strong>How large is my application and how much processing power does it need?</strong></p> <p>A physically large machine requires more dedicated wiring to reach spatially distributed points of operation from the central controller. The cost of wiring multiple routes from machine extremities to the central controller can become expensive. For a spatially large machine with distributed points of operation and control, it may be more cost-effective to process information locally using distributed control.</p> <p>Servicing a machine with multiple wiring paths may also prove problematic. Tracing service issues across a spatially large machine with distributed wiring can be time-consuming. Plus, distributed control can add to the process power by adding multiple nodes of decision-making capability.</p> <p><strong>What is the total cost of ownership?</strong></p> <p>Though smarter components are dropping in price, adding distributed control can initially be more expensive. However, OEM system integrators routinely look at the total cost of ownership for guidance on when to steer toward distributed control.</p> <p>Total cost of ownership takes into account manufacturing costs and service costs along with the initial purchase cost. Performance is another factor in determining total cost of ownership. If the solution becomes more efficient and/or productive with distributed control when compared with centralized control, that is worth consideration.</p> <p>Manufacturing and service costs can be reduced with distributed control. Control signals pass on a controller area network (CAN) bus rather than require dedicated wiring. Savings is realized in cost of materials and cost of assembly. Tracing problems and finding fixes is quicker and easier with network systems versus tracing physical wires. Added benefits with distributed control include more uptime and improved productivity and safety, as well as easier service.</p> <p><strong>How will distributed control prepare our designs for growth?</strong></p> <p>Simply put, machinery continues to become more complex as time goes on. Handling that increased complexity can look like an investment in dedicated wiring and larger, more powerful central controllers. But distributed control breaks with that complexity mindset by using communication across a CAN bus with easily added embedded systems.</p> <p>Incorporating more sensors and more hydraulic valves is a simpler matter when all communication is through a bus. Growing expectations about feedback, feedback signals, and fidelity of control are much more easily handled with distributed control. And since most engines over 50 HP are digitized, networking makes even more sense when considering the larger control picture.</p> <p>Smarter valves allow for more easily designed and easily altered control systems.&nbsp; Decentralized control is a way of physically breaking complex control problems into smaller control problems, and then solving them closer to the control operation itself.</p> <p><em>Chris Schottler is Engineering Manager&mdash;Advanced Technology Team at Eaton&rsquo;s Hydraulic Group.
