[0002] In many fields such as industrial production, municipal water supply, sewage treatment and chemical industry, pumps are a very critical equipment. Their main function is to transport various liquid media. However, these liquid media are often not pure substances, and may contain a large amount of solid impurities, such as metal debris and fiber particles generated in the industrial production process, sediment in municipal water supply, residues in sewage treatment and undissolved substances in chemical fluids. When the pump is running, if these solid impurities directly enter the pump body, it will cause a series of serious problems.
