How to Know When NOT to Use Fluid Power

hydraulic efficiencyIn the current inflationary environment, the debate concerning peak oil (the end of cheap mineral oil) and global warming (the end of the planet as we know it) have been somewhat sidelined.

But these two major issues have not gone away. And they will almost certainly influence the source and cost of our energy needs for some time to come.… Read more

Hydraulic Pump Leakage and Changeout

graphIn a condition-based maintenance environment, the decision to change-out a hydraulic pump or motor is usually based on either remaining bearing life or deteriorating efficiency, whichever occurs first.

Despite recent advances in predictive maintenance technologies, the maintenance professional’s ability to determine the remaining bearing life of a pump or motor, with a high degree of accuracy, remains elusive.

Deteriorating efficiency … Read more

How To Ensure Hydraulic Accumulator Reliability

Bladder and diaphragm accumulatorWhen properly applied in a hydraulic circuit, bladder and diaphragm accumulators can have a long and trouble-free life. But if their operating parameters are not correct, recurring failure can result. Consider this story from one of our members:

“Currently we are using a miniature accumulator from Hawe — part number AC 130-1/4, max. operating pressure 500 bar, max. gas fill … Read more
