Vickers Vane Pump, Vane Pump – 5 Fault Causes


      In the work operation, the vane pump will inevitably have various fault performances. What should happen to these faults? The    Vickers Vane Pump    here shares the five problem solutions for the vane pump for your reference.

  1. The vane pump is very noisy

  There are two reasons for high noise, insufficient oil in the fuel tank or wear on the pump core. When this problem occurs, first check if the fuel quantity is sufficient and then check the pump for problems.

  2. Blade pump system oil temperature is too high

  The reason why the system oil temperature is too high is that the system pipeline is too small, the pressure is too high, the hydraulic oil cannot be discharged in time, and the cooling system does not meet the requirements, causing the wind direction pump to be trapped.

  3. Vane pump system pressure drop

  The system pressure drop means that the vane pump can reach the predetermined pressure during operation, and the pressure gradually decreases during the working process, and the system cannot work normally. In this case, we should first check if the main control valve is leaking or the oil temperature is too high, and check if the upper and lower oil distribution plates are worn.

  4. No pressure

  This means that the vane pump has no pressure in the working system. First, check if the vane pump is draining hydraulic oil. Second, check that the oil pump is working in the right direction. Then, the coupling between the motor and the vane pump is normal. The final step is to check if the total pressure valve has failed.

  5. Pressure swing

  In this case, the pressure of the vane pump is unstable during operation. If there is no noise increase, the total pressure valve can usually be checked directly to see if it is worn. If it is a pumping problem, it will be accompanied by this noise increase.
