The vane pump consists of a rotor, a stator, a blade and a pump casing.
1. Rotor: It is the key part of the vane pump. It is usually cylindrical in shape and has a drive shaft in the center. The outer surface of the rotor has slots for placing the blades. When the rotor rotates, the blades expand outward under the action of centrifugal force and form a sealed cavity with the inner surface of the stator.
2. Stator: The stator is the stationary part of the vane pump. It is usually cylindrical and fits closely with the outer surface of the rotor. There is a series of annular grooves on the inner surface of the stator, which are used to guide the movement of the blades, thereby causing the volume of the sealed cavity to change.
3. Blades: Blades are the key components connecting the rotor and stator. They are placed in the slots of the rotor and move as the rotor rotates. One end of the blade is connected to the rotor, and the other end is in contact with the stator, forming a sealed cavity. When the rotor rotates, the blades expand outward under the action of centrifugal force, and continuously change the volume of the seal cavity as the rotor rotates.
4. Pump casing: The pump casing is the outer covering of the vane pump. It wraps the rotor, stator, blades and other components to form a complete pump body. There are usually inlet and outlet ports on the pump casing for the input and output of liquid.
These parts together constitute the basic structure of the vane pump. During the operation of the pump, the rotor rotates driven by the drive shaft, and the blades expand under the action of centrifugal force to form a sealed cavity. As the rotor rotates, the volume of the sealing chamber changes, thereby realizing the suction and discharge of liquid.
In general, the vane pump has an exquisite structural design and a simple and effective working principle, making it widely used in fields such as hydraulic transmission and hydraulic systems. Different vane pumps may have some slight differences in structure to adapt to different working conditions and performance requirements.
