China Vane Pump -Double Acting Variable Vane Pump Structure Characteristics
China Vane Pump commentary: The double-variable vane pump is formed by a certain structural improvement based on the existing double-acting quantitative vane pump. It is mainly composed of a stator, a rotor, a blade, an oil suction window, an oil discharge window, a floating block and a coupling spring. The stator and the stator bushing are arranged on the inner ring of the outer casing, and the rotor is arranged in the stator. The cloth is equipped with 8
sets of blades, and 8 sets of floating blocks are arranged uniformly in the middle of each set of blades. The floating block is composed of a floating block and a coupling spring; the floating block is installed in the floating block
chute, and the coupling spring is mounted on the spring. In the groove, a communication hole is opened at the bottom of the spring groove to the oil suction chamber, so that the hydraulic oil leaking through the floating block returns to the oil chamber through the communication hole, and the floating block can ensure smooth operation and flexible movement.
The new vane pump can automatically change the displacement according to the different requirements of the rotating speed while maintaining the advantages of the existing high-pressure quantitative vane pump SVQ25 rotor
radial force balance. The new double-acting vane pump and the traditional double The main difference between the low-pressure variable vane pump VDR 13 is that the part of the rotor between the two vanes is made of a floating part that changes with the change of the vane pump speed, so that the vane pump has a displacement when the rotational speed changes. The change is small or unchanged. It changes with the increase of the engine speed. The displacement of the booster pump will also increase with the increase of the pump displacement to achieve the purpose of reducing the pump output when the car is not turning.
