Pressure Intensification in Single Rod Cylinders

hydraulic cylinder failureA question I’m asked regularly is “What is the best way to test the integrity of the piston seal in a double-acting hydraulic cylinder?”

There is a simple bench-test for doing this but it involves the intensification of pressure in the cylinder. While the test procedure is safe if you understand the concept of pressure intensification in a hydraulic cylinder … Read more

How To Prevent Premature Hose Failures

hydraulic hoseHydraulic hose has a finite service life, which can be reduced by a number of factors. From a maintenance perspective, little or no attention is usually paid to the hoses on a hydraulic machine until a failure occurs. And hydraulic hose failures cost more than the replacement hose. Additional costs can include:

–Clean up, disposal and replacement of lost hydraulic … Read more

The Static Problem in Hydraulic Systems

Filter used on a filter cartBased on my experience at least, electrostatic discharge in hydraulic systems is not a widespread problem. But for reasons I’ll explain in a moment, it may be on the increase, so it’s definitely something you need to be aware of.

As you probably remember from school science experiments, electrostatic charge is generated whenever there is friction between two bodies moving … Read more
