Hydraulics At Work http://hydraulicspneumatics.com/blog/26271/feed Brendan Casey is a war-weary and battle-scarred veteran of the hydraulics industry. en The Filter Cart 'Rule of Seven' http://hydraulicspneumatics.com/blog/filter-cart-rule-seven <div class="node-body blog-body">Off-line filtration, whether permanently installed on a hydraulic system, or effected by the temporary installation of a portable filter cart, is a powerful bazooka in the contamination control effort. Without interfering with the operation of the equipment, the oil can be kept clean, in the former case, with full-time, offline filtration. Or, the oil can be flushed periodically with a portable rig, in the latter.</div> <p><a href="http://hydraulicspneumatics.com/blog/filter-cart-rule-seven" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/filter-cart-rule-seven#comments Hydraulics At Work Tue, 21 Mar 2017 00:56:00 +0000 42451 at http://hydraulicspneumatics.com A Word About Specific Heat Of Hydraulic Oil http://hydraulicspneumatics.com/blog/word-about-specific-heat-hydraulic-oil <div class="node-body blog-body">Based on specific heat alone, water appears to be a superior hydraulic fluid to oil. Because it takes twice is much heat, to get the same quantity of water to the same temperature. However, specific heat cuts both ways.</div> <p><a href="http://hydraulicspneumatics.com/blog/word-about-specific-heat-hydraulic-oil" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/word-about-specific-heat-hydraulic-oil#comments Hydraulics At Work Tue, 14 Mar 2017 01:57:00 +0000 42431 at http://hydraulicspneumatics.com Why Hydraulic Spool Valves Stick http://hydraulicspneumatics.com/blog/why-hydraulic-spool-valves-stick <div class="node-body blog-body">The radial clearance between the spool and bore in common, garden-variety directional control valves ranges between 3 and 13 microns. If the clearances between the spool and bore become invaded by hard particles (silt) or soft particles (varnish and sludge), more force is required to move the spool.</div> <p><a href="http://hydraulicspneumatics.com/blog/why-hydraulic-spool-valves-stick" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/why-hydraulic-spool-valves-stick#comments Hydraulics At Work Tue, 28 Feb 2017 00:19:00 +0000 42131 at http://hydraulicspneumatics.com When NOT To Use Wire-Reinforced Hydraulic Hose http://hydraulicspneumatics.com/blog/when-not-use-wire-reinforced-hydraulic-hose <div class="node-body blog-body">A recent client engaged me to design the hydraulic steering circuit for a luxury motor yacht he was building.

This is NOT to say all warranty claims are legitimate. In fact, it's very safe to say they're not. But when a hydraulic component fails prematurely, what IS needed is accurate information, i.e. better answers than 'it's contamination'.</div> <p><a href="http://hydraulicspneumatics.com/blog/why-accurate-failure-analysis-very-important" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/why-accurate-failure-analysis-very-important#comments Hydraulics At Work Tue, 03 Jan 2017 02:08:00 +0000 41331 at http://hydraulicspneumatics.com Hydraulic Troubleshooting: Start With The Basics http://hydraulicspneumatics.com/blog/hydraulic-troubleshooting-start-basics <div class="node-body blog-body">In any troubleshooting situation, no matter how simple or complex the hydraulic system, always start with the basics.
