The factors affecting centrifugal pump cavitation are issues that must be considered in the design and use of centrifugal pumps. In recent years, a lot of research has been carried out at home and abroad. However, due to different focuses of research, and most of them are conducted on a certain parameter that affects centrifugal pump cavitation, the research results are scattered and some of the opinions are contradictory. This article analyzes the impact on cavitation from the perspective of fluid physical properties.
