Reasons and solutions for hydraulic oil pump not being able to discharge oil

1. Reasons why the hydraulic oil pump cannot discharge oil

(1) Oil leakage

A common reason why the hydraulic oil pump cannot discharge oil is oil leakage. Oil leakage will cause the working oil pressure to drop, so that the pump cannot discharge oil normally. If the hydraulic oil pump cannot discharge oil, you should first check whether there is a leak in the hydraulic system.

(2) Intake valve failure

If the hydraulic oil pump cannot discharge oil and the problem of oil leakage has been ruled out, it is possible that the intake valve is faulty. Intake valve failure will cause the pressure to drop until the oil cannot be discharged smoothly. The solution to this problem is to check the intake valve and replace it in time.

(3) Internal damage to the pump

If oil leakage and intake valve failure are not the reasons why the hydraulic oil pump cannot discharge oil, it is possible that it is caused by internal damage to the pump. Internal damage to the pump will cause the pump to not work normally and cause it to be unable to discharge oil.

2. Solutions to the problem of hydraulic oil pump not being able to deliver oil

(1) Eliminate oil leakage

When the hydraulic oil pump cannot deliver oil, first eliminate the oil leakage problem and check whether there is leakage in the hydraulic system. If leakage is found, stop the vehicle immediately to check and replace the seal in time.

(2) Replace the intake valve

If the reason why the hydraulic oil pump cannot deliver oil is due to the failure of the intake valve, then you need to check the intake valve and replace it in time. A damaged intake valve will cause the oil to not be able to deliver oil normally until the pump cannot work.

(3) Repair internal damage to the pump

If the reason why the hydraulic oil pump cannot deliver oil is due to internal damage to the pump, then you need to inspect the inside of the pump and repair the internal damage to the pump. During the inspection, pay attention to carefully inspect and maintain the pump to ensure that the pump can work normally.

In short, the reason why the hydraulic oil pump cannot deliver oil is often due to oil leakage, intake valve failure or internal damage to the pump. The solution to this problem includes eliminating oil leakage, replacing the intake valve and repairing internal damage to the pump. If you encounter this problem, you can troubleshoot according to the above methods to ensure the normal operation of the hydraulic system.
