How does the vane pump working
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 an eccentricity between the rotor and stator.The blade can slide flexibly in the slot of the rotor. Under the action of centrifugal force during rotor rotation and the pressure oil at the blade root, the blade tip is closely attached to the inner surface of the stator, thus sealing working cavities are formed between two adjacent blades, oil distribution pan, stator and rotor.When the rotor rotates anticlockwise, the blade on the right side of the figure extends outwards, and the volume of the sealing working chamber increases gradually, creating a vacuum, and then the oil is inhaled through the Windows on the oil suction port 6 and the oil distribution plate 5.And on the left.As the blades indented, the volume of the sealing chamber gradually shrinks, and the oil in the sealing chamber is pressed out through another window of the oil distribution plate and the pressure port 1 and output to the system.This kind of pump in the process of a rotation of the rotor, oil suction pressure oil, so called a single action pump.Rotor radial hydraulic unbalanced force, it is also known as the non-balanced pump, its bearing load is larger.Change the stator and rotor eccentricity, you can change the displacement of the pump, so this pump is a variable pump.
