The Undamaged Reverse Design Research for the Impeller of Double-Suction Centrifugal Pump

The paper conducts the undamaged reverse design research on the impeller of the imported MABS double-suction centrifugal pump. With the reverse design engineering theory, the reverse designs of the structure, CAD hydraulic properties, and the processing and material of the impeller are carried out. It is proved that the impeller reverse designed is stable in operation and its hydraulic property criteria reach those of prototype pump.
