Insufficient flow of Vane Pumps Cartridge Kits is generally caused by what factors?

First, the inner surface of the stator is severely worn, which prevents the blades from maintaining good contact with the surface of the stator. The result is insufficient flow. The solution is simple, just replace the worn stator.

Second, the top cover screw is not tightened, and the axial gap increases, which promotes a decrease in volumetric efficiency, which leads to insufficient flow of the vane pump. At this time, ensure that the gap is uniform and the distance is appropriate, and the screws can be properly tightened.

Third, the vane pump system has large leakage, high pressure loss, and high conversion consumption, resulting in insufficient flow. It is necessary to check the vane pump components to see which component is causing the leakage.

Fourth, individual blades are loose and inflexible, which will cause the blades to not operate normally and cause insufficient flow. Therefore, it is necessary to keep the blades tidy. If this happens even when the leaf skins are tidy, consider replacing the deployed blades.

Fifth, the rotor and the blade are installed reversely: the installation direction of the rotor and the blade is reversed, and the operation is not normal. Therefore, when using the vane pump, it is necessary to maintain the consistency of the rotation direction of the blade and the rotor.

Sixth, the end face of the valve plate is severely worn: serious wear will cause various problems, and insufficient flow is only one of them. At this time, only the Fixed Vane Pumps can be replaced.
