     First, the working principle of single acting vane pump

    The pump is composed of rotor 1, stator 2, blade 3, oil distribution plate and end cover. The inner surface of the stator is a cylindrical hole. There is eccentricity between rotor and stator. The blade can slide flexibly in the rotor slot. Under the action of the centrifugal force when the rotor rotates and the pressure oil at the root of the blade, the top of the blade is close to the inner surface of the stator, so a sealed working cavity is formed between the two adjacent blades, the oil distribution plate, the stator and the rotor. When the rotor rotates counterclockwise, the blade on the right side of the picture extends outward, and the volume of the sealing working cavity increases gradually, resulting in a vacuum, so the oil is inhaled through the windows on the suction port 6 and the oil distribution plate 5. . While on the left side of the figure. The blade is retracted inwards, the volume of the sealing cavity is gradually reduced, and the oil in the sealing cavity is pressed out through the other window of the oil distribution plate and the pressure port 1 and is output to the system. In the process of rotating the rotor, oil and oil pressure oil is each time, so it is called a single-acting pump. The rotor is subjected to a radial hydraulic imbalance force, which is also known as a non-balanced type pump, with a large bearing load. The displacement of the pump can be varied by varying the amount of eccentricity between the stator and the rotor, so that the pump is a variable pump.
