Vane Pump Manufacturers - Pressure Limit Variable Vane Pump Principle


The vane pump manufacturer stated that the pressure-limiting variable vane pumping system is a single-acting oil pump. The stator of the pump can be translated in a certain direction. During operation, according to the change of
the system load, the variable pistons on both sides of the vane pump stator and The force balance principle of the preload spring can change the eccentricity of the variable pump stator and the variable pump rotor, thereby changing the flow of the variable vane pump.

Stable flow pump system {Double acting} vane pump: The rotor is sucked and drained twice every revolution.

Compared with the single-acting vane pump, the double-acting vane pump has good flow uniformity and the radial fluid pressure of the rotor body is basically balanced.

The double-acting vane pump generally performs quantitative flow out and acts to stabilize the flow.
