In this design, including single-stage single-suction clean water centrifugal pump design, the basic parameters centrifugal pump, centrifugal pump hydraulic design of leaves, water pump pressurized water chamber design, the water pump suction chamber design. As well as axial force and radial force balance, and finally to the strength check. The biggest difficulty pump design is the design of the pump seal, the new packing seal it can according to the change of the pressure to change the device sealing force. Keywords : Centrifugal pump; L eaves; P ressurized water chamber; S uction chamber 齐齐哈尔大学毕业设计(论文) 目录摘要.............................................................................................................................................
