What are the main parts of the multi-stage pump body?
- Mar 20, 2018 -

Multi-stage pump bodies can be divided into vertical multi-stage pumps and horizontal multi-stage pumps. Correspondingly, there are also some differences in the multi-stage pumps of different multi-stage pumps. At present, in the production of multi-stage pump body, the main materials used are stainless steel, lg and da.


In fact, the multi-stage pump also belongs to the centrifugal pump. During the operation, the centrifugal force is obtained through the high-speed rotation of the impeller. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, so that a high vacuum is gradually obtained. Multi-stage pump refers to a pump with two or more impellers. The maximum head can exceed 125 meters. The basic structural components of the multi-stage pump body include inlet pipes, diversion casings, check valves, pump shafts and impellers.


The multistage pump body is actually the main working part of the multistage pump, and the impeller inside the pump body belongs to the core part of the whole device. During the operation of the multi-stage pump, the rotation speed of the impeller is high and the output force is large. At the same time, the blades on the impeller also play an important role. The impeller passes the static balance experiment before assembly. The inner and outer surfaces of the impeller are required to be smooth in order to reduce the friction loss of the water flow.
