Hydraulics At Work http://hydraulicspneumatics.com/blog/26271/feed Brendan Casey is a war-weary and battle-scarred veteran of the hydraulics industry. en Hydraulics Know-How: Just-In-Case versus Just-In-Time http://hydraulicspneumatics.com/blog/hydraulics-know-how-just-case-versus-just-time <div class="node-body blog-body">A 'just in time' approach to learning (or learning more) about hydraulics is great in theory but doesn't work very well in practice. Because for just in time learning to work for you, you need to be able to define exactly what you need to know - and when you need to know it. And the trouble with hydraulics is, you never really know what it's going to throw at you next!</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hydraulics-work">Hydraulics At Work</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/hydraulics-know-how-just-case-versus-just-time" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/hydraulics-know-how-just-case-versus-just-time#comments Hydraulics At Work Mon, 29 Jun 2015 22:41:00 +0000 33111 at http://hydraulicspneumatics.com One Simple Way To Remove Water From Hydraulic Oil http://hydraulicspneumatics.com/blog/one-simple-way-remove-water-hydraulic-oil <div class="node-body blog-body">If you've worked with hydraulic equipment for any length of time, it's likely that you've come across a hydraulic system with cloudy oil.

When oxygen combines with hydrocarbon molecules a chain reaction occurs, which results in the formation of organic acids. These substances darken the oil, increase viscosity, reduce foaming resistance and air release, and form varnish and sludge. In other words, the oil becomes unserviceable.</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hydraulics-work">Hydraulics At Work</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/why-you-should-know-your-hydraulic-oils" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/why-you-should-know-your-hydraulic-oils#comments Hydraulics At Work Mon, 15 Jun 2015 22:39:00 +0000 33081 at http://hydraulicspneumatics.com The Biggest Challenge Hydraulics Users Face Today http://hydraulicspneumatics.com/blog/biggest-challenge-hydraulics-users-face-today <div class="node-body blog-body">A lot of hydraulic equipment users - large and small - are in the same boat.

But overall efficiency is NOT one of them. A single-reduction gearbox has an efficiency of 98 to 99 percent, double-reduction 96 to 97 percent and triple-reduction 95 percent. A chain drive in good condition has an efficiency of 97 to 98 percent.</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hydraulics-work">Hydraulics At Work</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/how-size-hydraulic-oil-cooler" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-size-hydraulic-oil-cooler#comments Hydraulics At Work Tue, 12 May 2015 00:45:00 +0000 32301 at http://hydraulicspneumatics.com A Problem With Hydraulics At High Altitude http://hydraulicspneumatics.com/blog/problem-hydraulics-high-altitude <div class="node-body blog-body">At 3000 ft, air only has 90% of its sea level density. So a fixed-speed cooling fan will move the same volume of air but at only 90% of the mass. And it's the air mass that removes heat from the hydraulic oil heat exchanger. The heat transfer coefficient of this thinner air is lower too. This means the heat exchanger may be only 75-80% as effective as it would be at sea level.</div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hydraulics-work">Hydraulics At Work</a></li> </ul></div><p><a href="http://hydraulicspneumatics.com/blog/problem-hydraulics-high-altitude" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/problem-hydraulics-high-altitude#comments Hydraulics At Work Tue, 05 May 2015 00:45:00 +0000 32221 at http://hydraulicspneumatics.com Predictive Hydraulics Maintenance 101 http://hydraulicspneumatics.com/blog/predictive-hydraulics-maintenance-101 <div class="node-body blog-body">In the appendix of Reliability-Centered Maintenance II, John Moubray lists 102 proactive maintenance techniques in six categories.
