Cause and Solution of Casing Jamming of Vane Pump from hong yi's blog

There should be many friends who have encountered this kind of problem when the vane pumpis stuck in use. How should we solve this problem? We will explain it to you in the following content.

1. It may be that the axial clearance or radial clearance inside the pump body is too compact.

2. It may be that the concentricity of gear pump cover plate and shaft does not conform to the size that can be specified; Solution: The cover plate can be replaced to make it concentric with the shaft.

3. It is possible that the concentricity adjustment of pump and motor coupling is not in place; Solution: You can adjust the distance between the concentricity of the pump shaft and the motor coupling. The specified distance cannot exceed 0.01 mm.

4. It may be due to the failure of the pressure valve; Solution: A new pressure valve can be replaced.

5. It is possible that the vane pump contains some impurities. Solution: Fine silk screen can be used to filter out some dirt from engine oil.
