This project mainly includes the schematic design of the single stage single suction clean water centrifugal pump, the selection of the basic parameters of the centrifugal pump, the hydraulic design of the centrifugal pump blades, the hydraulic design of the centrifugal pump pressure chamber and the hydraulic design of the suction chamber of the centrifugal pump. And to balance the axial force and radial force and, finally, check the force.The biggest difficulty in the pump design is the pump seal. This design uses a new type of gasket seal, which can change the sealing force according to the pressure change. According to the structural characteristics and sealing principles of traditional seals, the loading of the seal is analyzed. The irrational force caused by the gasket; from a mechanical point of view, the structure of the traditional gasket seal has been modified and the shortage of the new gasket seal with reverse force has been proposed, which has made the principle and structure of the gasket seal more Reasonable, its sealing performance and life useful are improved, which has a certain reference value.
