Preventing sewage pumps from being contaminated by water requires comprehensive consideration of aspects such as selecting the right pump, regular cleaning and maintenance, increasing fluid velocity, intelligent monitoring and maintenance, and environmental management and safety measures. Through the comprehensive application of these measures, the risk of sewage pumps being contaminated by water can be effectively reduced, ensuring the normal operation of the sewage treatment system.

As a key equipment for fluid transportation, pumps are widely used in various fields. However, during the operation of the pump, cavitation often occurs, which not only affects the performance of the pump, but also may cause damage to the pump's flow-through parts and shorten the service life of the pump. Therefore, in-depth research on the cavitation phenomenon of the pump is of great significance to improving the operating efficiency and safety of the pump.
