With the continuous advancement of technology and the continuous expansion of the market, micro submersible pumps will be used in more fields. The new trend of submersible pump structural design is to develop towards miniaturization. This trend not only meets the market demand for small, efficient and convenient submersible pumps, but also meets the requirements of environmental protection and sustainable development.

The factors affecting centrifugal pump cavitation are issues that must be considered in the design and use of centrifugal pumps. However, due to different research focuses, and most of them are research on a certain parameter that affects centrifugal pump cavitation, the research results are relatively scattered. , and some of the views are contradictory. This article analyzes the impact of centrifugal pump structural design on cavitation in centrifugal pumps.
