Centrifugal pump is a widely used engineering machinery, mainly including ISG pipe centrifugal pump, ISW pipe centrifugal pump, IHG stainless steel pipe centrifugal pump, etc. What I will summarize today is the cavitation problem of centrifugal pumps. The next content is based on the centrifugal pumps produced by Shenyi Pump.

Cavitation of the centrifugal pump occurs because there are some local low-pressure areas near the inlet of the medium entering the pump body. The pressure here will reduce the saturated vapor pressure of the medium, leading to a small part of the medium being vaporized. Therefore, the factors that can reduce the local pressure at the inlet of the centrifugal pump to below the medium vaporization pressure are the main incentives for cavitation of the centrifugal pump. This phenomenon of centrifugal pump can be regarded as the main disadvantage of centrifugal pump. It not only reduces the working efficiency of centrifugal pump, but also greatly reduces the purity of its medium delivery.

Faced with such disadvantages, it is necessary to solve the cavitation phenomenon of centrifugal pump from the following three points: first, the characteristics of suction device; Second, the structure of the pump body itself; Third, the characteristics of the medium to be conveyed. Only by fundamentally solving this problem can we reduce the frequency of its occurrence and improve the efficiency of centrifugal pumps.

Because of this, the researchers of Shenyi Pump Industry, starting from the above three aspects, overcame it step by step, bit by bit, and finally solved the problem that plagued the centrifugal pump perfectly. Such achievements will not only bring great changes to the production enterprises, but also bring great benefits to the using enterprises.
