the structure and design features of the drainage pump are mainly reflected in the impeller design, mechanical seal, cable inlet, pump body structure, installation and operation, and maintenance and care. These characteristics make the drainage pump efficient, stable, safe and reliable, and can meet the needs of different users.

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.
