Electric Hydraulic Pump Troubleshooting

by Taylor

If a problem with hydraulics occurs, the pump should be one of the first components to be replaced; however, it is not the final one. Pumps are among the most expensive and time-consuming components and should only be replaced once several tests have been conducted. Before deciding on a replacement, we’ll discuss some of the easiest tests and checks you can perform.

Electricity and hydraulic pressure are both extremely risky. You must put safety first on your list of priorities. Don’t take shortcuts, even if it means you risk security.

Be aware of the system.

The electric-powered hydraulic pump is just one part of a larger system. It is essential to know how the pump and every other component interact with one and each another. Learn and review the system’s schematics, study the manufacturer’s specifications, be aware of the capabilities of each component, and understand the function of every component and how it is a part of the whole system.

Your system will only be the best as the weakest component. If, for instance, you have an electronic pressure transducer with a tolerance of 5 per cent, the highest range you can anticipate your system’s pressure to be will be 5 per cent. A 5 per cent tolerance to hydraulic pressure equals enormous pressure in the headband.

Call the operator

If the system was running, contact the operator. Ask about the symptoms and when the issue is discovered, the location where the issue occurs and the severity of the issue within the system. Alongside describing the symptoms, an operator may also provide some history. It’s common to hear the operator recall how the previous maintenance crew resolved the issue.

Test the system

You can run the system yourself to experience the full impact of the issue. If you need to be more careful with the system, watch when someone else is operating it. It’s an excellent idea to ask someone else to explain the issue. This way, it is not necessary to trust other people’s opinions.

Ensure that all components are correctly connected.

Lay out the schematic of the system and then compare the sketch with the whole system. Follow the flow of the circuit. Check your electrical wiring is in order. Find any differences between the diagram and the actual system. Concentrate on the differences.

Check the pump’s mechanical operation.

When you’re sure that the pump’s electronic components are functioning, test the mechanical operation of the device. Check the suction pipe, and look for any air leaks or restrictions. Check the flow and pressure at the port for pressure on the pump. Verify that there is no excessive flow coming from the drain of the case on the pump. 

Examine the pump’s speed and the direction of rotation. Make sure the temperature is within the normal range. Test the pilot pressure to be sure there’s pressure at the time it is supposed to be. It is equally important to ensure any pressure, even though there should be no pressure.

Repair the suspected malfunctioning component.

Based on the information you have gathered through the steps above, You should now have a clear idea of the issue’s root. You should think about it again, focusing specifically on your pump. If you believe an instrument is not working, replace it and test the system. If you suspect a problem with your pilot’s system, you can open the system and look for signs of damage from contamination. Clean the components before re-testing the system.
