How to troubleshoot a hydraulic system? |Magister Hydraulics

The sources of hydraulic system failures can be tricky to identify, but some troubleshooting steps can help narrow down the possible options. So how do you troubleshoot a hydraulic system? Here are some of the fundamentals.

Check the motor: Ensure the motor has the correct wiring and can turn on and off.

Check the fluids: Check the level, color and viscosity of the hydraulic oil to ensure it meets manufacturer’s specifications and has not become contaminated. When in doubt, drain and replace the fluids right away.

Check hydraulic gear pump: Take the pump assembly apart and assess all parts to ensure that they are all functional and are installed correctly. The most common problem areas include the pump shaft, shaft key (if any), joining couplings and a filter. Try to run your pump to see if it supplies the oil or not. 

Check relief valves and lines: Observe all lines for potential leaks and tighten every connection point. Also, check the relief valve settings for any signs of damage or improper set up.

Check hydraulic control valve: Track the lines that are connected to the hydraulic control valve to make sure that you set up is correct and oil is supplied to the control valve from your pump. Try to use one of the levers to see if there is a sufficient pressure and oil travels to the desired location.

Run the system: When you have completed all these essential checks, turn on the system and monitor it for pressure and temperature fluctuations, as well as abnormal sounds. If all seems well, check your pressure sensor for potential failure.
