It involves a lot of science and sometimes, a bit of art. Incorrect diagnosis prolongs downtime and can result in the unnecessary repair or replacement of serviceable components. To avoid these costly mistakes, a logical approach based on sound troubleshooting principles is required.</div> <p><a href="http://hydraulicspneumatics.com/blog/how-avoid-hydraulic-troubleshooting-mistakes" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-avoid-hydraulic-troubleshooting-mistakes#comments Hydraulics At Work Tue, 31 May 2016 01:29:00 +0000 38481 at http://hydraulicspneumatics.com How To Reduce Noise Emission From Hydraulic Systems http://hydraulicspneumatics.com/blog/how-reduce-noise-emission-hydraulic-systems <div class="node-body blog-body">The magnitude of noise radiation from an object is proportional to its area and inversely proportional to its mass. Reducing an object's surface area or increasing its mass can therefore reduce its noise radiation. For example, constructing the hydraulic reservoir from thicker plate (increase in mass) will reduce its noise radiation.</div> <p><a href="http://hydraulicspneumatics.com/blog/how-reduce-noise-emission-hydraulic-systems" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-reduce-noise-emission-hydraulic-systems#comments Hydraulics At Work Tue, 24 May 2016 00:25:00 +0000 38461 at http://hydraulicspneumatics.com How To Deal With Water In Hydraulic Oil http://hydraulicspneumatics.com/blog/how-deal-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.

It's hard to believe planned hydraulic oil changes accounted for much more than a third of this volume. So where is all the rest going? I bet the coal from this mine burns better than most. And it's safe to assume hydraulic oil leaks are not the least of their problems.</div> <p><a href="http://hydraulicspneumatics.com/blog/why-you-should-record-all-hydraulic-oil-top-offs" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/why-you-should-record-all-hydraulic-oil-top-offs#comments Hydraulics At Work Tue, 03 May 2016 00:36:00 +0000 38111 at http://hydraulicspneumatics.com Hydraulic Component Repair Using Aftermarket or Non-Genuine Parts http://hydraulicspneumatics.com/blog/hydraulic-component-repair-using-aftermarket-or-non-genuine-parts <div class="node-body blog-body">The economics of proceeding with any hydraulic repair is ultimately dependent on the cost of the repair, relative to the cost of a new component. As a rule, the more expensive the new component is in absolute dollar terms, the more likely it is that a repair will be cost effective. The cost of a hydraulic repair is determined by a number of factors.</div> <p><a href="http://hydraulicspneumatics.com/blog/hydraulic-component-repair-using-aftermarket-or-non-genuine-parts" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/hydraulic-component-repair-using-aftermarket-or-non-genuine-parts#comments Hydraulics At Work Tue, 26 Apr 2016 00:41:00 +0000 38051 at http://hydraulicspneumatics.com The Effect of Temperature On Static Hydraulic Pressure http://hydraulicspneumatics.com/blog/effect-temperature-static-hydraulic-pressure <div class="node-body blog-body">In 'The Hydraulic Troubleshooting Handbook' I lay out a step-by-step SYSTEM for reliable and efficient troubleshooting.

Design on price alone (especially if you don't know what you're doing) and you'll end up with a load of rubbish. Sure, there are lots of hydraulic equipment users out there who don't know any better.

Big pump. 1000 L/min at up to 350 bar. And, at the time, worth about $40,000. You can imagine: dirty mine-site, excavator covered in dust, and a 6-inch diameter inlet hose open to the elements. So one of the fitters stuffs a rag into the pump's inlet hose to keep the dirt out.

To say this another way, even when a port in a spool valve is closed off - a small amount of leakage should be expected. Whereas the other main valve design used in hydraulics - the poppet type, where the valve 'poppet' closes against a seat IS generally considered leak free. </div> <p><a href="http://hydraulicspneumatics.com/blog/one-important-fact-about-hydraulic-spool-valves" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/one-important-fact-about-hydraulic-spool-valves#comments Hydraulics At Work Tue, 01 Mar 2016 00:28:00 +0000 37251 at http://hydraulicspneumatics.com How To Troubleshoot Hydraulic Cylinder Drift http://hydraulicspneumatics.com/blog/how-troubleshoot-hydraulic-cylinder-drift <div class="node-body blog-body">A popular misconception about hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift down. Fact is, if the piston seal is completely removed from a double-acting hydraulic cylinder, the cylinder is completely filled with oil and its ports are plugged, the cylinder will hold its load indefinitely - unless the rod-seal leaks.</div> <p><a href="http://hydraulicspneumatics.com/blog/how-troubleshoot-hydraulic-cylinder-drift" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-troubleshoot-hydraulic-cylinder-drift#comments Hydraulics At Work Tue, 23 Feb 2016 00:37:00 +0000 37151 at http://hydraulicspneumatics.com
