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.

The vertical multi-stage centrifugal pump is a non-self-priming vertical multi-stage centrifugal pump designed and manufactured by absorbing advanced domestic and foreign technologies. It uses a standard vertical motor and a quick-install mechanical seal, which is very convenient to replace. A slight carelessness during the installation of a vertical multi-stage centrifugal pump will lead to improper installation and affect the performance of the pump in the future.

Submersible sewage pumps often cause motor windings to burn out due to lack of water in the pool. The main components of WQ submersible sewage pump are composed of impeller, pump body and base submersible motor. Modified sewage pumps are mostly used in construction sites, septic tanks and other environments with sewage and debris. The water pump and the all-copper motor are on the same shaft. Since the water pump is located at the bottom of the entire sewage pump, it can maximize the suction of residual sewage on the ground.

Centrifugal pumps are an integral part of industrial fluid delivery systems and are widely used in petrochemical, pharmaceutical, food processing and many other fields. As a key component of a centrifugal pump, the performance of the mechanical seal directly affects the operating efficiency and safety of the pump. However, in practical applications, mechanical seal damage is a common problem, which will not only lead to a decrease in pump efficiency, but may also cause safety hazards such as leakage. Therefore, it is of great practical significance to explore the causes and treatment methods of mechanical seal damage of centrifugal pumps.
