But despite my loud and regular protests to the contrary, the &#39;Holy Grail&#39; of all hydraulics skills is and always has been: troubleshooting.<br /> <br /> Yup, whether you and I like it or not, the hot-shot troubleshooter, the man who can cast his eye over a hydraulic system and quickly zero-in on the fault without breaking sweat, is &#39;Top-Gun&#39; in the hydraulics world.<br /> <br /> He&#39;s a soldier of fortune. Admired by some; envied by many.<br /> <br /> Given troubleshooting expertise is such a valuable and sought after skill, have you ever wondered why there&#39;s so many millwrights, mechanics, technicians and engineers out there equipped with nothing more than a trial and error, hit and miss, pluck and chuck approach to troubleshooting?<br /> <br /> Beginning of last year one of my <a href="http://www.hydraulicsupermarket.com/pro-club.html">Hydraulics Pro Club</a> members engaged me in a conversation about the skill of troubleshooting (it IS a skill all on its own). And to cut a long story short, his view was that most mechanics, technicians and engineers will never become competent troubleshooters, no matter how much effort is put into them, because they lack the necessary talent.<br /> <br /> In other words, he was suggesting troubleshooting can not be taught; or if it can, only to those candidates with the right aptitude.<br /> <br /> I didn&#39;t automatically agree with this assessment. That troubleshooting ability is some kind of black art which can only be mastered by those gifted with special powers. And it&#39;s a view I&#39;d come across before. But since it wasn&#39;t an issue I&#39;d stopped and given a lot of thought to, I went away and pondered it at length.<br /> <br /> After spending some time considering my own experience and that of the many technicians I&#39;ve worked with, supervised and trained over the years, I came to the conclusion that troubleshooting is NOT any kind of black art at all.<br /> <br /> It is indeed a learned skill.<br /> <br /> And if something can be learned, it can be taught.<br /> <br /> Furthermore, I concluded that learning how to troubleshoot effectively is NOT like learning math, where you need mathematical aptitude, or learning music where you need musical talent. In other words, I&#39;m convinced NO mystical powers are required to become an expert troubleshooter.<br /> <br /> Bottom line: troubleshooting is a skill anyone can learn. Anyone who wants to that is.<br /> <br /> But what does it mean, to be an expert troubleshooter? Contrary to what many believe, it has almost nothing to do with the ability to read a hydraulic schematic.<br /> <br /> While the ability to read schematics is usually helpful in a hydraulic troubleshooting situation, it&#39;s a secondary skill. I&#39;ve been able to read a schematic for 25 years or more, but it hasn&#39;t stopped me from making more than a few troubleshooting mistakes during that time. And when I&#39;m troubleshooting something other than a hydraulic system, the ability to read a schematic is no help to me at all.<br /> <br /> And this is why the troubleshooting process and procedures I explain in my new troubleshooting handbook can be applied equally effectively to ANY system. Not just a hydraulic system. Because troubleshooting is troubleshooting.<br /> <br /> For example, last year my wife, Jay started to feel ill after meals. She hadn&#39;t long recovered from an illness that required surgery. So she wasn&#39;t at all keen to start seeing doctors again. And as a result she was putting up with the discomfort.<br /> <br /> I started paying attention to exactly what we ate at meal times and how she felt afterwards. After a couple of days of careful observation it occurred to me that she may have developed gluten intolerance. I shared my observation with Jay, and she agreed, as a test, to eliminate all wheat products from her diet. And the result was as immediate as it was remarkable. 15 months later, she still hasn&#39;t been &#39;medically&#39; diagnosed as gluten intolerant, but it&#39;s hardly necessary. Because if she inadvertently eats anything containing even a trace of gluten, it makes her feel sick.<br /> <br /> Clearly, I&#39;m not a doctor. But the process I went through to troubleshoot my wife&#39;s condition, is the same process I use when troubleshooting a hydraulic system. And note that my ability to read a hydraulic schematic was NOT the key. My understanding of the troubleshooting PROCESS was.<br /> <br /> And while on the subject of doctors, if you need further evidence that system knowledge in and of itself is NOT the key to effective troubleshooting, consider the medical profession. The vast majority of doctors are highly qualified. And yet hardly a day goes by when you don&#39;t read or hear about a misdiagnosis that had serious, even fatal consequences for the patient. Doctors use the term: misdiagnosis. I call it what it is: a troubleshooting mistake.<br /> <br /> Fortunately, unlike doctors, we in the hydraulics biz don&#39;t &#39;bury&#39; our troubleshooting mistakes. Still, there&#39;s plenty of room for improvement.<br /> <br /> P.S. Troubleshooting mistakes are usually expensive, but so too are the maintenance mistakes I outline in <a href="http://www.hydraulicsupermarket.com/track?p=handp&amp;w=smr">&quot;Six Costly Mistakes Most Hydraulics Users Make...

But to minimize LOMOC, having a reliable machine is not enough. A highly efficient, reliable machine is required. So this begs the question: <strong>how efficient are your hydraulic machines?</strong><br /> <br /> As a hydraulics consultant advising clients in a diverse range of industries, the issue of efficiency is one I deal with a lot. Let me illustrate this with a couple of examples:<br /> <br /> One client, the designer of a three-wheeled vehicle, approached me to design a hydraulic drive. He wanted to power at least two-wheels, ideally three.<br /> <br /> To keep cost to a minimum, the machine designer asked me to consider gear pumps and motors. A gear pump or motor in good condition is 85 percent efficient. So a gear pump driving a gear motor has a best-case efficiency of 0.85 x 0.85 = 0.72. That&#39;s 72 percent - not considering losses through valves and conductors.<br /> <br /> But say a gear-type flow divider was included to achieve multiple wheel drive. The theoretical efficiency would now be 0.85 x 0.85 x 0.85 = 0.61. That&#39;s 61 percent, not including losses through valves and conductors. Compare this with a chain drive in good condition, which is 97 to 98 percent efficient. This explains why you don&#39;t see many hydraulic bicycles around!<br /> <br /> In this particular application where the available input power is limited by space and weight, the question I had to ask my client was: Can you afford to lose 40 to 50 percent of available input power to heat? In his case the answer was no. But in a similar industrial application we have the option of installing a bigger electric motor - and then paying for it over the life of the machine!<br /> <br /> Another client, examining his options for a rotary drive in a remote location with no access to the electricity grid. He can generate his own electricity but likes the idea of using an air motor. He wants to know comparative costs. It&#39;s not a big drive - only 20 horsepower.<br /> <br /> An air motor has an efficiency of around 15 percent. So I explained to my client that to drive his 20 horsepower air motor he&#39;ll need a 140 horsepower air compressor! That pretty much settles it in his application. He&#39;s not going with the pneumatic option. In a plant situation though, we might just order a bigger compressor without thinking too much about it - and then keep paying for it for years to come!<br /> <br /> Contrast these two examples with this one: another client for whom I am advising on the design of a 6,000 ton press. Regardless of efficiency, hydraulic power transmission is really his only option. But this is also a relatively efficient use of hydraulics. One of the reasons for this is that the efficiency of a hydraulic cylinder in this type of application approaches 100 percent.<br /> <br /> Because it&#39;s a high-pressure application, piston pumps will be essential. The overall efficiency of an axial piston pump in good condition is 92 percent. So the theoretical efficiency of the press hydraulic circuit is 0.92 x 1.00 = 0.92 or 92 percent - not including losses through valves and conductors.<br /> <br /> A significant, &#39;built-in&#39; inefficiency in this application however, is the compressibility of the hydraulic fluid particularly given the necessarily high working pressure and large volume of the cylinder. But clearly, this is not an application for gear or chain drives.<br /> <br /> This is not to say hydraulics, and even pneumatics, aren&#39;t appropriate solutions for rotary drives. Energy efficiency is just one of many issues that must be considered when selecting a power transmission option. But like the many factors that influence machine reliability, if efficiency is overlooked at the design stage and not considered during the equipment selection process, this can increase ownership cost and therefore unit cost of production. And perhaps even more so in the years come, if energy costs continue to increase.<br /> <br /> So when you&#39;re acquiring new equipment, be aware of and consider the efficiency of the various power transmission options. And remember that in the case of hydraulic power transmission, proper maintenance is essential - not only to ensure the equipment operates efficiently, but also reliably.

There is confusion and controversy over its function, where it should be located, what size it should be, how it should be piped &mdash; and whether it is needed at all. Air receivers are one of the least understood, yet potentially most useful components available to increase operating efficiency. But an air receiver should be an integral part of any plant air system &mdash; mainly to enhance its efficiency. Here are the classic purposes:</p> <p><strong>Contaminant removal</strong> &mdash; A bare receiver (without a pressure regulator or flow controller) adds a large volume to the piping system. This volume reduces air-flow velocity and encourages finely divided particles of liquid lubricant or condensate to drop out of the air stream. These separated liquids can then be drained from the receiver, rather than traveling with the compressed air or gas to create adverse downstream effects.</p> <p><strong>Pulsation damping</strong>&mdash; A receiver installed near the compressor discharge dampens pressure pulses from positive-displacement compressors (rotary or reciprocating) to a small fraction of their original amplitude. This reduces the probability of excess compressor power or shortened service life resulting from resonant response to the frequency of compressor delivery.</p> <p><strong>Pressure stabilization</strong>&mdash; A receiver combined with a pressure regulator or flow controller can create an effective pressure band or differential between the supply side and the demand side. A typical example: 95 psig in the receiver, 90 psig steady to the system. This allows the demand side to operate at its lowest effective pressure, and therefore lowest volume demand. Stored air with a pressure differential creates volume held in reserve to cover short-term peak demands that exceed current air supply &mdash; without turning on or loading another compressor.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Air-receiverWEB_0.jpg" style="width: 300px; height: 188px; float: right;" title="This 80-gal air receiver is ready to have a compressor, drive, relief valve, and other components installed to make a complete power source of compressed air." />A one-atmosphere pressure change (less than 15 psi) accommodates a free air volume equal to that of the receiver. This can be used in the primary receiver, in a secondary receiver on the demand side (to serve an operation with surge demand), or even as off-line peak-shaving storage.</p> <p><strong>Augment compressor controls</strong>&mdash; Receivers with appropriate volume can reduce and decelerate pressure changes caused by intermittent use of compressed air. Compressor controls, which normally respond to pressure, can smoothly regulate compressor output without frequent ranging through their full control span. If an operation has capacity controls, but only a short run of pipe, a receiver will provide the total storage volume needed for the control to perform effectively.</p> <p>Other effective ways to manage a stable pressure exist, depending on system dynamics. A networking control system can manage the compressed-air supply to hold a set target pressure at the system entry. Also, a variable-speed drive trim compressor can hold a pressure differential as low as 1 psig throughout its full operating range, eliminating the control band rise.</p> <p><strong>Pressure stabilization</strong>&mdash; A receiver combined with a pressure regulator or flow controller can create an effective pressure band or differential between the supply side and the demand side.

After all, it takes 8 hp of electricity to produce 1 hp of compressed air. Air no longer was perceived as free. Its cost should,<br /> and could, be managed.</p> <p>Early efforts in compressed-air cost management focused on the obvious &mdash; controlling leaks and lowering usage. But after a significant reduction in air usage, an energy audit often revealed little or no reduction in actual electric power consumed. This disappointing result usually came because of the absence of an air receiver, combined with poor or too small interconnecting piping from the compressor to the system entry.</p> <p>Insufficient effective storage did not allow the compressor capacity controls to translate lower air demand into lower input energy. Without effective storage, most unloading controls could not establish and hold enough idle time as a percent of running time. Nor could they optimize the automatic start/stop control and shut off.</p> <p>The normal operating band for a compressed air supply is 10 psig. Effective storage capacity is created at the location where this band is neutralized In other words, a 10-psig operating-pressure band is neutralized at the point where 10 psid is needed to get air through the interconnecting piping, dryer, filters, etc. and into the demand system.</p> <p><em>Hank van Ormer is President, Air Power USA Inc., Pickerington, Ohio.

Behind the scenes, much of the action is thanks to state-of-the-art hydraulic drives.</p> <p>Bosch Rexroth, headquartered in Lohr am Main, Germany, and with U.S. operations based in Charlotte, N.C., has a group of engineers and technicians dedicated just to stage technology. For more than three decades, the company has supplied leading-edge, easy-to-operate systems for venues ranging from small theaters to large performing-arts centers. Projects vary from quick modernization during short holiday shutdowns to extensive overhauls of all stage machinery.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Image-1---Power-units.jpg" style="width: 233px; height: 350px; float: right;" title="The ability to mount hydraulic power units remotely from actuators ensures quiet stage movements. " />Stage motion systems usually rely on a combination of hydraulic, electromechanical, and hybrid drives, but the high-power density and compact footprint of hydraulics often makes it the go-to solution when moving large loads or during space-constrained retrofits. Today&rsquo;s advanced electronic controls permit quick dynamic movements and high operating speeds. And because hydraulic power sources can be installed remotely from the actuators, this ensures extremely quiet movements while preventing heat generation near the stage.</p> <p><strong>Stage subsystems</strong></p> <p>The drives are used in mechanisms and machinery above and below stage, including movable floors, platform lifts, and even special set decorations. Hydraulic drives are also routinely used in equipment like lighting hoists and portal bridges.</p> <p>For example, when a scene changes, powered hoists above the stage ensure that backdrops and other settings are placed precisely where needed or quickly removed. They are often installed as an alternative to manual counterlines during renovation and new construction projects.</p> <p>Hydraulic cylinders in these applications can reach considerable lengths. Rexroth has installed drives with a lift capacity of 14 m, but even greater heights are possible. If required lifting heights or other conditions rule out a linear drive, hydraulic rotary drives are an excellent alternative.</p> <p>Hydraulic cylinders operate completely jerk-free across a wide range of speeds. Even when fully loaded, speeds of up to 1.8 m/sec are not unusual and, thanks to high power density, the drives are extremely compact. For instance, they can be mounted at axis intervals of 200 mm on a stage wall to replace conventional manual counterweight systems, and additional space for winches is unnecessary.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Image-2---Control-console.jpg" style="width: 300px; height: 212px; float: left;" title="Rexroth’s SYB 3.0 stage controls handle electrohydraulic and electromechanical drives. Real-time communication ensures precise synchronization of motion sequences." />In the often-tight confines below stage, hydraulics&rsquo; compactness and high force capability offer designers an advantage, as they&rsquo;re considerably smaller than equivalent electromechanical drives. For example, an orchestra is seated in a pit for opera or ballet performances but needs to be onstage for a concert. Hydraulic drives can move orchestra rostrums to the exact height a specific performance demands.</p> <p>The same holds for stage podiums and platforms. Powerful hydraulic drives quickly move these structures, some weighing tons. Moreover, highly dynamic movements are both smooth and silent. This is particularly beneficial for equipment like stage lifts and elevators. Independent electrohydraulic control of individual actuators lets operators position various sections at different heights or even tilt them at an angle. Likewise, many performances quickly change scenes by rotating sets mounted on a turntable. Hydraulic drives provide the power to move heavy sets without jolts that could topple the displays.</p> <p><strong>Technical considerations</strong></p> <p>Ensuring that all motion-control drives run as intended requires sophisticated controls. Rexroth&rsquo;s SYB 3.0 stage-control system is engineered specifically for the control and automation of stage machinery, and is reportedly easy to program and operate. The systems&rsquo; modular design handles electrohydraulic and electromechanical drives, giving users the flexibility to tailor stage movements to the exact demands of set designers and theater directors.</p> <p>High bandwidth ensures real-time communication with all drives for precise synchronization and optimally coordinated motion sequences. The software includes integrated 3D simulation tools, and several operators can simultaneously program the same or different performances &mdash; features that promote workflow efficiency. And the controls are designed to easily allow for future expansion, modernization, or alteration of the drives.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Extra-Image-4---Lighting.jpg" style="width: 300px; height: 200px; float: right;" title="Hydraulics is often used to position large lighting bridges. " />SYB 3.0 controls also have a collision &ldquo;assistant&rdquo; that warns of conflicts before they happen and helps operators ensure safe movements. In fact, safety is a prime concern when engineering stage equipment. It is now customary practice in many localities to operate stage safety devices hydraulically, or by combining an electric drive with a hydraulic brake &mdash; because these designs most reliably comply with technical safety requirements.</p> <p>For instance, should a fire ever break out, active fire-safety devices like smoke vents keep pressure from building inside the stage house and let smoke and toxic gases escape. Hydraulic cylinders that operate independent from the main electricity supply are used with redundant safety circuits to ensure simple operation and positive response.</p> <p>Like most any operation today, opera houses, theaters, and convention centers -- large and small -- face budget constraints, so energy costs are a prime concern. Rexroth has responded with a range of options that include not only efficiency-optimized components, but entire systems with interactive feedback that minimize power consumption. One example is speed-controlled pump drives that only deliver the required pressure and flow when operations demand, and otherwise slow or completely stop. &nbsp;</p> <p>The company also offers systems that make it possible to recycle the braking energy in the form of hydraulic pressure &ndash; for instance, when lowering a podium. It&rsquo;s intensified, stored in accumulators, and fed back into the circuit as needed. Thus, the pump and power unit have to generate less flow and pressure, which ultimately saves electrical energy and lowers operating costs.</p> <p><strong>Applications</strong></p> <p><strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Extra-Image-3--Bolshoi.jpg" style="width: 300px; height: 206px; float: right;" title="Rexroth engineers upgraded Moscow’s Bolshoi Theater with more than 600 hydraulic and electric drives.

For instance, the famed Bolshoi Theater in Moscow was upgraded with more than 600 hydraulic and electrical drives as well as the stage control system. Built in 1825 and now a World Heritage site, the external building dimensions had to remain unchanged during renovation.</p> <p>It includes a stage pit more than 20 m deep with seven large stage platforms.

But just because compact construction machines are smaller than their full-size counterparts doesn&rsquo;t mean they can skimp on power. They still need plenty of force for digging, high torque for drilling, and enough power to work quickly.</p> <p>This is where the high power density of hydraulics is essential. The Toro Co., Bloomington, Minn., offers its Dingo line of compact utility loaders for building, utility, landscape contractors, equipment rental facilities, or anyone who needs a powerful machine small enough to work in confined spaces.<strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Lead-1promo_0.jpg" style="width: 300px; height: 199px; float: right;" title="" /></strong> Dingo compact loaders pack an impressive amount of power into a small package. For example, the Model TX-427 has a 27-hp diesel engine, yet is only 34.5-in. wide. The loaders are also versatile, with more than 35 attachments available to tackle digging, hauling, demolition, grading, and other heavy-duty work.</p> <p><strong>Small and versatile</strong></p> <p>Toro&rsquo;s Dingo tracked loaders share several design features common to full-size loaders and excavators. For example, Dingo TX-427 compact loaders have twin hydrostatic crawler drive circuits &mdash; each capable of delivering 16.9 gpm of hydraulic flow to each track wheel motor. <img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Quick-change-actweb-.jpg" style="width: 139px; height: 350px; float: right;" title="Toro’s Dingo compact loaders use manifold-mounted cartridge valves to conserve space and simplify hydraulic plumbing." />They also have individual hydraulic pumps for work functions &mdash; 6-gpm for the loader arm and 11.4 gpm for auxiliary hydraulics. This provides up to 19 hp of hydraulic power for attachments requiring high flow, such as auger drives.</p> <p>Another important design feature of Dingo loaders is the use manifold-mounted cartridge valves. The manifolds conserve space over line-mounted valves by incorporating multiple valve functions into a single unit. The cartridge valve units also reduce the amount of hose and tubing needed, thereby eliminating potential leak sources and further conserving space.</p> <p>And as with full-size loaders and excavators, compact equipment has become more versatile for contractors by making it quicker and easier to change attachments. This is especially important for smaller contractors who cannot afford to purchase several specialized machines. Instead, by changing an excavator shovel for a concrete breaker, the contractor can use one machine for many different jobs.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Toro%27s-DingoWEB.jpg" style="width: 200px; height: 143px; float: left;" title="Quick-change act: Toro’s Dingo compact excavators let users change out attachments in three quick-and-easy steps. From top, the attachment’s mounting plate is placed on the dingo, twist pins lock the attachment into place, and dripless flush-face hydraulic couplers are connected." />However, complicated attachment changeout may require operators with special skills and take excessive time. Toro avoids these potential drains on productivity with a simple, three-step attachment change procedure. An operator simply mounts a standard attachment plate to the TX-427, twists pins to lock the attachment in place, and connects quick-acting hydraulic couplings to the machine&rsquo;s loader arms. The hydraulic couplings in the TX-427 have a flat-face design that prevents hydraulic oil leakage and also keeps contaminants out of the hydraulic system.</p> <p>The attachments themselves have shielded seals to hold hydraulic leakage at bay and also prevent dirt, water, and other contaminants for entering the hydraulic system.</p> <p>For more information on Toro&rsquo;s Ding line of compact loaders, visit <a href="http://www.toro.com/dingo" target="_blank">www.toro.com/dingo</a>, or email <a href="mailto:dingo@toro.com">dingo@toro.com</a>.</p> <p>&nbsp;</p> <table border="1" cellpadding="1" cellspacing="1" height="528" width="566"> <tbody> <tr> <td style="background-color: rgb(153, 204, 204);"> <h3> <strong>Mini excavator loaded with big features</strong></h3> <p>A big trend in small construction equipment is to capitalize on the features of full-size equipment while retaining the benefits of compact design.

C., offers an energy-saving alternative to conventional fixed-speed hydraulic power units (HPUs) using variable-displacement pumps. Instead, the industrial HPU drives a fixed-displacement pump at variable speed. This technique drives the pump at the speed necessary to provide the required flow up to 20 lpm &ndash; all while maintaining a constant pressure for clamping or other functions.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/2014.08-HAWE_0.jpg" style="width: 300px; height: 300px; float: right;" title="HAWE’s NSMD clamping module, used in conjunction with a variable-speed HPU, reduces energy consumption in manufacturing operations by maintaining closed-loop pressure control." />The speed of a variable-frequency drive is commanded by a hydraulic pressure sensor, and its signal is processed in a frequency converter. The rapid reaction time of the control loop prevents pressure drops and peaks when the volume flow requirement changes. It also stops the motor when no flow is required, rather than have a pump operate at near-zero displacement.</p> <p>HAWE&rsquo;s NSMD clamping module sets and monitors clamping pressure through an integrated switch; it transmits proportional signals from the machine&rsquo;s control system to the valve&rsquo;s proportional solenoid. It not only measures whether the clamping pressure is correct but also evaluates whether the clamping cycle is complete. This means the release signal can be used directly for starting the machine, thus eliminating the need for a pause to ensure the clamping motion is completed.</p> <p>Machines such as lathes can also operate without the clamping module if the workpiece clamping device is the only hydraulic unit being supplied by the power pack. The clamping pressure can then be set directly via the motor speed. Pressure and volume flows are matched to consumption requirements to ensure correct pressure is applied at the right time.</p> <p>&nbsp;</p> <p>For more information, call HAWE Hydraulics at (704) 509-1599, go to <a href="http://www.hawe.com" target="_blank">www.hawe.com</a>, or visit them at IMTS booth E-4930.</p> </div> <div class="og_rss_groups"></div> http://hydraulicspneumatics.com/controls-instrumentation/vfds-help-hpus-be-more-efficient#comments Controls & Instrumentation Fri, 15 Aug 2014 16:39:00 +0000 28321 at http://hydraulicspneumatics.com A Flak Jacket for Hose http://hydraulicspneumatics.com/hose-tubing/flak-jacket-hose <div class="node-body article-body"><p>Today&rsquo;s hydraulic hose is tougher than ever. Manufacturers now offer a wide variety of extra-tough cover materials that resist chemicals, heat, sunlight, and abrasion. But in some of the most demanding applications, providing more protection can extend the hose life even further. That&rsquo;s where hose sleeves come in.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/2014.08-Essentra.jpg" style="float: right; width: 235px; height: 390px;" title="Essentra sleeves and straps extend life of hydraulic hose by keeping them from rubbing against abrasive surfaces and containing hydraulic fluid that may leak from the hose." />Hose sleeves provide an extra barrier of protection from environments that can cause premature failure of hose. In some cases, as with hose protection sleeves from Essentra Components, Forest Park, Ill., this barrier can also help protect personnel. If small leaks occur in a high-pressure hose, Essentra sleeves help contain the leak. Mine-Safety Approved TSL is made of a Polyamide 6, a tough, synthetic fabric that is dense enough to contain oil, yet lightweight. The TSL easily slides over hose assemblies while the TQS series has a hook-and-loop seam that is ideal for field installation and adjustment.</p> <p>Also offered are Nylon 22 cinch straps and hanging cinch straps. Cinch straps act as a belt for bundling hoses together, and the hanging version has a grommet so one or more hoses can be supported from or attached to an adjacent structure. Delrin or Nickel-plated steel buckles with hook-and-loop fasteners allow just enough tension to hold the hose assembly securely. When secured to a structure the hanging version can also be used as an adjustable alternative to hose clamps.</p> <p>For more information on Essentra Components hose protection call (800) 847-0486 or go to <a href="http://www.essentracomponents.com" target="_blank">www.essentracomponents.com</a>.

LLC (vollrath.com), Sheboygan, Wis. Vollrath makes a huge variety of both simple and sophisticated products and equipment related to food and beverages &mdash; from ketchup squirt bottles to stainless steel cookware and food preparation machines to sophisticated serving stations that keep salads cool and soups hot.</p> <p>Vollrath uses huge quantities of stainless steel for the products it manufactures. It also makes extensive use of hydraulics to press, bend, and form the material into the required shape for the finished components and products.</p> <p><strong>Short cycles required</strong></p> <p><strong><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/2014.08-Vollrath%20lead%20image-courtesy%20Hotel%20F%26B%20.jpg" style="width: 350px; height: 199px; float: right;" title="Vollrath Co. makes a wide variety of professional kitchen and service items, including these contemporary-looking steam table trays made on a hydraulic press using an unconventional position sensor." /></strong>One of the products Vollrath cranks out in high volume is trays for steam tables and salad bars, which are typically found in cafeterias, self serve stations, and restaurants. Trays within a family share a common footprint. For example, all trays may measure about 12-in. wide by 20-in. long but have different depths depending on their capacity. A 12- by 20-in. tray may come in depths of 2, 4, 6, or 8 in.</p> <p>The trays are typically made from stainless steel sheet that is cut to size, annealed, then transferred to a hydraulic press. Depending on the trays&rsquo; dimensions and other application parameters, they may go through multiple pressing and annealing operations.</p> <p>The press has an upper die powered by hydraulics for motion and pressing force. A single die can be used for most or all trays within a family &mdash; the only difference being their depth. The lower die&rsquo;s cavity is matched to the length and width of the upper die, and its depression can accommodate the deepest pan. For shallower pans, the bottom of the cavity is positioned upward. Once the tray has been pressed, a pneumatic cylinder in the bottom-center of the die rapidly extends to eject the newly formed tray out the the lower die. The machine operator then places the tray on a conveyor for the next production operation.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/2014.08-Vollrath%20second-Tray%20in%20press.jpg" style="float: right; width: 288px; height: 400px;" title="This stainless steel tray is being ejected from a hydraulic press by a pneumatic cylinder using a closed-loop light sensor to control stroke." />Vollrath formerly had to set the depth of the lower die using shims and spacers. The time for setup ate into production time, so Werner Kraenzler, manufacturing engineer at Vollrath, looked for a way to automate positioning of the bottom of the die. Integrating a control with the eject cylinder would offer a simple and compact solution, but conventional methods posed serious limitations.</p> <p>Kraenzler wanted a position sensor that could be adjusted remotely. Reed and proximity switches could not easily be repositioned, and linear pots would not stand up to the repeated shock of the hydraulic press. Plus, stray EMI and RFI noise could interfere with many other types of sensors.</p> <p><strong>Arriving at a solution</strong></p> <p>Kraenzler found a solution with the iNSiGHT air cylinder from Motion Controls LLC, Hartford, Wis. Brad Engstrad, president of Motion Controls explained that iNSiGHT is a pneumatic cylinder of standard dimensions incorporating QVLA technology for internally sensing position of the cylinder&rsquo;s piston. The patented QVLA technique uses light from an LED to illuminate the volume inside the cap end of the cylinder. As the piston moves closer to or away from the cap end, the intensity of the reflected light changes accordingly. A light-detecting diode senses the change in reflected light, which correlates to the piston position. Circuitry within the QVLA generates an electrical signal representative of piston position, and without having to use magnets or gun-drilled piston rods.</p> <p>Kraenzler says that instead of having to set the depth of the die manually, operators can now extend or retract the cylinder&rsquo;s piston rod until a digital readout shows the target position. After the position is locked in, the operator can resume production of trays with the press set to the new depth. The quick-change act not only increases productivity, but also makes the press more versatile by allowing a variety of sizes to be run on a single machine.</p> <p>For more information on iNSiGHT cylinders and QVLA technology, call Motion Controls LLC at (262) 673-9255, or visit <a href="http://motioncontrolsllc.com" target="_blank">motioncontrolsllc.com</a>.</p> </div> <div class="og_rss_groups"></div> http://hydraulicspneumatics.com/controls-instrumentation/sensor-sets-table-simplicity#comments Controls & Instrumentation Fri, 15 Aug 2014 15:51:00 +0000 28301 at http://hydraulicspneumatics.com August 2014 Hydraulics & Pneumatics http://hydraulicspneumatics.com/hydraulics-pneumatics/2014-08-15 <div class="node-body magazine_issue-body"></div> <fieldset class="fieldgroup group-mag-teasers"> <div class="field-mag-teaser"> <a href="/news/giant-carrier-has-24-hydraulic-steerable-axles">Giant carrier has 24 hydraulic steerable axles</a> <a href="/construction/mighty-minis-construction">Mighty Minis of Construction</a> <a href="/news/imts-makes-its-way-chicago">IMTS Makes Its Way to Chicago</a> </div> </fieldset> <fieldset class="fieldgroup group-publication-info"><legend>Publication Info</legend> </fieldset> <div class="og_rss_groups"></div> Fri, 15 Aug 2014 04:00:00 +0000 28361 at http://hydraulicspneumatics.com From the Editor: Making a Connection in Wisconsin http://hydraulicspneumatics.com/cylinders-actuators/editor-making-connection-wisconsin <div class="field-deck"> Meeting Vollrath Man, and discovering the part that pneumatic cylinders play at this giant foodservice equipment manufacturer. </div> <div class="node-body article-body"><p>I had the pleasure of visiting <a href="http://vollrath.com" target="_blank">The Vollrath Co.

Kuebler&rsquo;s Mannheim, Germany, facility recently received two giant self-propelled mobile transports (SPMTs) manufactured by Scheuerle Fahrzeugfabrik GmbH, Pfedelbachm, Germany, for lifting and transporting stacks of steel plate weighing up to 250 tonnes. Each of these powerful giants is about 25-m (82-ft) long and has 24 hydraulically steered and powered axles.<br /> <img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/02_NonCassetteCarrier.gif" style="width: 585px; height: 430px; margin: 5px; float: left;" /></p> <div class="related-content"> <div class="related-label"> Related</div> <p><a href="http://hydraulicspneumatics.com/construction/bobcat-triples-productivity-new-bore-finishing-system">Bobcat Triples Productivity with New Bore-Finishing System</a></p> <p><a href="http://hydraulicspneumatics.com/news/imts-makes-its-way-chicago">IMTS Makes Its Way to Chicago</a></p> <p><a href="hydraulicspneumatics.com/200/TechZone/HydraulicPumpsM/Article/False/84565/TechZone-HydraulicPumpsM">Steerable wheel drives make loader light and nimble</a></p> </div> <br /> <p>Much of the equipment Kuebler moves is too large even for one of these vehicles, so two or more may be used in concert to move an entire oil platform, tunnel-boring machine, ship, or other structure. The SPMTs are driven, steered, and provide lifting via hydraulics. Depending on the application, a single hydraulic power unit may serve multiple vehicles. When an especially large load requires more than one transport unit, an SPMT containing the HPU can be connected to other vehicles using hydraulic couplings. A hydraulic motor powers drive wheels, and the SPMTs are raised and lowered by 14 hydraulic lifting forks linked to each axle.

The lift was used for moving large equipment and workers in and out of the mine, which ran 24/7. Refer to the accompanying schematic for an overview of the hydraulic system.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Mine-Lift-Layout.gif" style="width: 585px; height: 574px; margin: 5px; float: left;" />The mine&rsquo;s maintenance department determined from past experience their supply of water for cooling was in poor condition. Consequently, the hydraulic system&rsquo;s four-pass water-cooled heat exchanger needed to be reamed out, cleaned, and resealed every six months. Technicians installed a reconditioned heat exchanger, but the hydraulic system was still running hot &mdash; even though swapping out the heat exchanger solved the problem in the past. They concluded something else was causing the excessive heat.</p> <p>Technicians first checked a cooler-bypass check valve that was mounted separately. It seemed in good operating condition. A standby pump-motor unit was brought online, but switching to it did not solve the problem. Case-drain flowmeters and pump pressures on both units seemed to be fine.</p> <p>They then surmised that the problem was probably in the motor circuit because it ran most of the time. A new hydraulic motor was installed, but the problem still persisted. Next, a new filter element was installed, but that didn&rsquo;t help, either.</p> <p>Finally, for some reason, they then replaced an accumulator. Of course, this did not solve the problem, so what do you suggest?</p> </div> <div class="og_rss_groups"></div> http://hydraulicspneumatics.com/mining/troubleshooting-challenge-mine-lift-overheating-problem#comments Mining Tue, 12 Aug 2014 20:13:00 +0000 28081 at http://hydraulicspneumatics.com Bobcat Triples Productivity with New Bore-Finishing System http://hydraulicspneumatics.com/construction/bobcat-triples-productivity-new-bore-finishing-system <div class="field-byline"> John Smallshaw, Engis Corp. </div> <div class="node-body article-body"><p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Bobcat-S570.jpg" style="width: 350px; height: 234px; margin: 5px; float: right;" />For more than 50 years, Bobcat skid-steer loaders have represented durability and reliable performance for construction, landscaping, and agricultural applications. The key to a dependable loader is to have properly balanced horsepower and hydraulics so operators can work efficiently in rugged conditions. With an eye to continuous product performance and reliability improvement, Bobcat recently invested in an Engis bore finishing system, which not only improved the quality of a key hydraulic component, but increased manufacturing throughput 300%.</p> <h3> Tightening the Process</h3> <p>Previously, Bobcat finished the control valves on its skid-steer hydraulic pump bodies by using a multipass honing system that required operator manipulation with each part. The honing machine would make a pass to finish three 15.877‑mm (0.6251-in.) diameter bores on the G2 steel casting. Then, an operator would move the part 180&deg; on the die so the machine could make a second pass through the valves on an off-set bore.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Fig-1-EngisFPMComponents.jpg" style="width: 350px; height: 241px; margin: 5px; float: left;" title="Simultaneous precision finishing and gauging of four bores in a hydraulic valve body. Using the Engis system enabled Bobcat to reduce cycle time from 253 to 89 sec/part." />&ldquo;We had to take extra measures to make sure the valves wouldn&rsquo;t leak,&rdquo; said Dean Cota, Bobcat Sr. Manufacturing Engineer. &ldquo;We had to run the honing system through multiple times because each spindle had only one stone on it. Each head would go through the bore three times to perform the roughing, semifinish, and finish steps. Then we would manually reposition the part and run it through again.&rdquo;</p> <p>The finishing process was slow and required extra operator care to guarantee tight bore tolerances. While researching other honing options that would improve productivity, Cota discovered Engis&rsquo; single-pass bore finishing, which provides a multispindle head that hones with three/four tools in close proximity to each other. This unique arrangement allows the roughing, semifinish, and finishing operations to be performed simultaneously on all of the valve bores in a part.</p> <p>Engis custom designed the single-pass bore finishing system to Bobcat&rsquo;s specifications. The machine has six stations for which the part is transferred through by a rotary index table.</p> <ul> <li> Station #1 is the load/unload position.</li> <li> In station #2, a vision system is used to verify that the part is loaded correctly and that the proper part is present for the current program being run.</li> <li> Stations #3, #4, and #5, each have independent servo controlled columns, with four spindle multiheads for holding the diamond honing tools.</li> <li> Station #6 utilizes an independent servo controlled column with a head holding four multijet gage probes. This gauge unit allows every land of every bore to be inspected in the <em>X</em> and <em>Y</em> planes for size. The gauge also has advanced features which allow it to measure the bore sizes of the rough and semifinish operations on command.</li> </ul> <p>The Engis system achieves tolerances to 0.5 &mu;m (0.000020&nbsp;in.) ensuring bores are consistently straight and cylindrical, which are critical for the spool and valve bore to fit properly in the hydraulic system. When hydraulic valves perform optimally, they can withstand a higher pressure, which improves overall performance of the skid-steer loaders.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/Fig-2-EngisFPMComponent2.jpg" style="width: 350px; height: 234px; margin: 5px; float: right;" title="The Engis system eliminates the need to reposition the part to finish it, reducing system time and eliminating a potential source of error." />The single-pass boring process is achieved through a series of progressively finer, high-precision electroplated diamond tools. The diamond size grit on the tools are to 100/120, 200/230, and 325/400. The free-floating nature of the tooling results in superior bore consistency and a faster cycle time.</p> <p>The old multipass honing system took 253 sec/part, which included two boring passes, resetup of the machine and flipping parts. The new single-pass boring system takes 89 sec, improving throughput by nearly 300%.</p> <h3> Reducing Errors</h3> <p>By automating the bore finishing system and reducing operator contact with the parts, Bobcat has reduced the chance for mistakes.</p> <p><img alt="" src="/site-files/hydraulicspneumatics.com/files/uploads/2014/08/fig-3-CrankBores.jpg" style="width: 300px; height: 303px; margin: 5px; float: right;" title="Engis can custom design specialty machines to finish all bores simultaneously for maximum productivity." />Operator transition to the new single-pass bore finishing system was simple due to built-in CNC programming. The machine&rsquo;s vision system identifies that the right parts are loaded before the program runs, which further prevents errors.</p> <p>The advanced gauging system 100% inspects and measures the bores for geometric precision so that every part coming off the line is exactly to spec.</p> <p>Because the single-pass process spreads the workload over a series of high-precision electroplated diamond tools, Bobcat requires very few tooling changes, which saves on consumable costs.</p> <p>&ldquo;We ran the machine for six months, six days a week for 20&nbsp;hr a day before we had to change the tooling. At an average run of 165&nbsp;parts/day, we produced nearly 24,000 parts before we needed to change out the tooling,&rdquo; noted Cota.</p> <p>The new Engis bore finishing system has decreased cycle times to the point that the plant can take on additional honing production without requiring any additional capital investments.</p> <p>____________________</p> <p><em>JOHN SMALLSHAW, vice president of sales and marketing, Engis Corp., Wheeling, Ill.
