Is your hydraulic pump unable to generate pressure? There are many problems that can cause this. The best practice is to eliminate the most obvious reason, lest you will not end up with a perfect pump and only find that the problem is not big. In order to help, we have compiled a list, this articleZhongyou Heavy IndustryBring how to solve the hydraulic pump can not produce pressure failure.
1) Check your direction control settings.
It sounds obvious, but the direction control is often inadvertently changed without the knowledge of the maintenance staff. There is no need to spend time verifying the position of the manual control device and checking the settings of the electric solenoid control device, but if you do this instead of replacing the perfect pump, you will feel much better.
2) Check if your pump is receiving fluid.
Factors such as restrictions and blockages may prevent fluid flow to the pump. This may result in poor fluid flow, air leakage in the suction pipe, air in the pump at startup, insufficient oil supply in the pump, blocked or dirty fluid filters, blocked inlet lines or hoses, blocked reservoir vents, low oil in the reservoir, etc.
3) Check whether your drive motor is reversed.
Now that we have ensured that the direction control will not be reversed, it is time to check whether the drive motor itself is rotating in the correct direction. Sometimes, incorrect installation will cause the pipe wiring between the control valve and the motor to mismatch, thereby reversing the flow direction. Check to make sure that the motor rotates the pump in the correct direction; if it is not correct, check the pipeline.
4) Check whether the drive motor is running correctly.
Check to make sure that your pump drive motor is turning over and is developing the required speed and torque. In some cases, misalignment may cause the drive shaft to stick, preventing the motor from turning. In this case, please correct the misalignment and check whether the motor is damaged. If necessary, repair or replace the motor.
5) Check whether the pump coupling is damaged.
Check to ensure that the pump to motor coupling is not damaged. The shear pump coupling is obviously the cause of the failure, but the position of some pumps in the hydraulic system makes it difficult to check and may be ignored
6) Check your pump pressure relief valve.
The entire flow may flow through the safety valve, preventing pressure build-up. Check whether the safety valve has been properly adjusted according to the pump specifications and application.
7) Check for mechanical damage.
Bearing, pump shaft or other internal damage may prevent the pump from running together. If everything else is not resolved, please disconnect the pump and the motor and check whether the pump shaft can rotate. If not, repair or replace the pump.
8) hydraulic pump troubleshooting.
If your pump encounters problems developing sufficient power, please follow this checklist to help you pinpoint the problem. In some cases, you may find a simple solution. If your pump has any other problems, such as noise issues, heat issues, or flow issues, you may need to conduct more investigation to resolve the root cause of the pump problem.
