The hydraulic system was running a synthetic ester, biodegradable hydraulic fluid. This $45/gallon hydraulic fluid had been destroyed in under 12 months and a set of pumps shortly after. So with $20,000 of hydraulic fluid and $50,000 of pumps ruined in short order, my client was understandably wondering what went wrong.</div> <p><a href="http://hydraulicspneumatics.com/blog/anatomy-hydraulic-maintenance-failure" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/anatomy-hydraulic-maintenance-failure#comments Hydraulics At Work Tue, 01 Nov 2016 01:26:00 +0000 40651 at http://hydraulicspneumatics.com How To Consolidate Your Hydraulic Oil Inventory http://hydraulicspneumatics.com/blog/how-consolidate-your-hydraulic-oil-inventory <div class="node-body blog-body">How many different types of hydraulic oil are taking up space in your oil store?

This single-stage cylinder was 6" bore x 3" rod x 14' 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! 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?</div> <p><a href="http://hydraulicspneumatics.com/blog/troubleshooting-tales-squealing-hydraulic-cylinders" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/troubleshooting-tales-squealing-hydraulic-cylinders#comments Hydraulics At Work Tue, 06 Sep 2016 04:33:00 +0000 39931 at http://hydraulicspneumatics.com The REAL Value Of The Humble Hydraulic Symbol http://hydraulicspneumatics.com/blog/real-value-humble-hydraulic-symbol <div class="node-body blog-body">As most hydraulic technicians know, there's usually a better than even chance that a schematic diagram will not be available for the hydraulic machine they've been called in to troubleshoot.
