Some Common Do’s and Don’ts When Using Hydraulic Pumps

Blog | December 8th, 2016

Powerful prime movers transfer torque to hydraulic pumps. The designs used in these fluid engines vary from one system to the next, but the source of power rarely changes. Basically, we’re talking about the heart of the system, a core mechanism that requires a firm set of operational rules if it’s to function as designed. Let’s look at the do’s and don’ts when using hydraulic pumps. That way, we’ll always keep this system-critical component working within its design boundaries.

Don’t Trace Leaks Tactilely 

If a pinhole leak is suspected near a hydraulic pump, don’t use a hand to trace the location of the nearly invisible leak. A pressurized hose is dangerous. The leak could actually punch a hole through human skin, just like a syringe needle. Mark the general area where the leak is taking place and call in a repair service.

Don’t Use the Wrong Hydraulic Oil 

Power transmitting fluids function as motion propagators and heat distribution aids. Assess the oil for its viscosity rating and its general ability to shift heat. The life of the machinery shortens when the oil doesn’t match the hydraulic pump’s load handling capabilities. Obviously, overall performance also diminishes, as this is the center of the mechanisms operating universe we’re talking about here. Additionally, on taking the above metaphor to its logical conclusion, the oil is the blood being pumped by a beating hydraulic heart, so it must be clean and exhibit a viscosity grade that fits in with the pumps mechanical constitution.

Do Observe Duty Cycle Usage Patterns 

An efficient system draws fluid-based mechanical energy when required, but an overburdened system loses this ability as it teeters on the edge of failure. Under ideal conditions, keep track of the load factor and check the pump housing for the effects of a possible overload. Heat is an obvious side effect here, as is a marked increase in vibrations and rapid valve shifts. The latter event could indicate a systematic increase in pressure spikes, which would inevitably trace back to the stressed hydraulic pumps.

In conclusion, use premium oils in the system, and don’t look for a leak, not when it could cause a nasty injury. Next, do treat these do’s and don’ts with all due care, like a finely tuned machine deserves. Maintain the system, replace filters, and don’t allow this resolute heart to run hot. Finally, hydraulic pumps are expensive, so do keep oil free of contaminants, the foreign matter that will cause the mechanical heart to age and falter.
