Basic Structure Of Centrifugal Pump
- Aug 29, 2018 -

The basic structure of centrifugal pump is composed of eight parts: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, seal ring, packing box, axial force balance device.

1. Impeller is the core part of centrifugal pump. It has high rotational speed and high output power.

2, pump body also known as pump shell, it is the main body of the pump. The utility model plays a supporting and fixing role, and is connected with a bracket for mounting the bearing.

3. The function of the pump shaft is to transfer the torque of the motor to the impeller by connecting the coupling with the motor, so it is the main part of transferring mechanical energy.

4, seal ring is also known as reducing leakage ring.

5. The packing box is mainly made of fillers, which prevent the water flow from the pump to the outside or the air from the outside into the pump. Always keep the vacuum in the pump. When the friction between the pump shaft and the packing generates heat, it is necessary to fill the cooling water by sealing the water pipe into the water seal ring.

6. Axial force balancing device, in the process of centrifugal pump operation, because the liquid enters the impeller under low pressure, and flows out under high pressure, so that the pressure on both sides of the impeller varies, resulting in axial thrust pointing to the inlet direction, will cause the rotor axial movement, resulting in wear and vibration, so axial thrust bearing should be installed. In order to balance the axial force.
