Parameter optimization of centrifugal pump impeller

After the hydraulic calculation of the centrifugal pump, some design parameters of the impeller can be obtained. The axial projection of the impeller can then be drawn by conventional methods, but in the process, the determination of some parameters in the axial projection map ignores whether it is an optimal solution. In this paper, orthogonal test method is used to determine the optimal solution and optimal combination of some design parameters in the axial projection map, to achieve multi-objective optimization, and to optimize the axial projection of the impeller, improve the flow curve of the impeller and improve Work efficiency.
