Why does the vane pump use a pump core component in its structure?

The use of pump core components in hydraulic press vane pumps is a major structural feature of vane pumps at home and abroad, which is easy to assemble and maintain. The pump core components can be purchased separately, making maintenance easier.

The pump core assembly contains all parts of the pumping mechanism, consisting of the rotor, blades, stator and oil distribution plate with waist-shaped oil inlet and outlet. The blades are installed in the rotor. When the rotor is rotated by the prime mover, the blades are thrown out under the action of centrifugal force, move along the inner curved surface of the stator, and remain in contact with the inner surface of the stator, forming a gap between the top of the blade and the stator. Reliable sealing.

The rotor and stator are installed eccentrically. When the rotor rotates, changes in volume increase and decrease occur between the stator and blades. There is an oil port in the stator, and the oil distribution plate is used to separate the oil inlet chamber and the oil outlet chamber. The oil distribution plate is installed on the side of the stator, rotor and blade assembly. Its oil suction port is located at the part where the volume increases, and the oil outlet is located at the part where the volume decreases. All oil enters and leaves the pumping mechanism through the oil distribution plate (of course, The oil suction port and oil outlet of the oil distribution plate are connected to the oil suction port and oil outlet in the pump housing respectively).
