Testing hydraulic pumps is crucial for maintaining and optimizing their performance. The process includes assessing flow and pressure, case drain function, and RPM. Regular testing of oils and filters is also necessary to prevent costly repairs or replacements.
Testing hydraulic pumps is an essential process for maintaining and maintaining any system that includes hydraulic pumps. While the exact process will vary depending on the configuration of the motors used to drive the pumps and the intended use of the pump, it is very likely that several checkpoints will be included in any test strategy. These checkpoints include assessment of the quality of the flow and pressure at each pump port, the function of the case drain, and the revolutions per minute generated by the hydraulic motor.
Pressure and flow are essential for the efficient operation of any type of hydraulic pump. Any type of hydraulic pump test will include measurements of both the flow of fluid through the system and the amount of pressure driving that flow. The current pressure level should be within the acceptable range set by the manufacturer, resulting in a flow of hydraulic fluid which in turn helps keep the wear of the machinery within acceptable parameters.
Flow and pressure are also critical to the function of the case drain feature which is part of the pump design. With this aspect of hydraulic pump testing, the goal is to make sure that the discharge exhibits acceptable levels of flow and pressure which results in maintaining a safe temperature for all pump components. In the event that the pressure level is not within acceptable standards, this could be a sign that one or more components need replacement.
Controlling the revolutions per minute (RPM) speed is also a key element of any type of hydraulic pump testing. Lower rpm could mean that something is creating friction that results in slower returns, or that one or more components are worn out and need to be replaced. The test helps reduce the chance of any sort of permanent damage occurring, requiring costly repairs or even the replacement of the entire pump.
Testing the hydraulic pump will also involve evaluating the condition and functionality of the oils and filters used as part of the pump’s ongoing operation. It’s not unusual for testing to occur at least on a quarterly basis, with many companies opting to run some level of testing on a monthly or even bi-weekly basis. The frequency of the evaluations and the scope of the tests will vary depending on the complexity of the pump design and the amount of use of the machinery.
