• W4225126590 abstract "This paper aimed to systematically maximize hydraulic efficiency and pump head for mine drainage pump using numerical simulation method and optimization design method. First, the preliminary design of the pump is carried out according to the traditional design method, and then the impeller and diffuser of mine drainage pump are optimized by orthogonal test method and computational fluid dynamics numerical simulation method aiming at the hydraulic efficiency of the pump. The results show that under the rated working conditions, the hydraulic efficiency of the optimized mine drainage pump is 82.11%, the pump head is 25.94 m, and the hydraulic efficiency and pump head are increased by 3.58% and 1.53 m, respectively. Furthermore, under the flow conditions of 0.8 Q d , 1.0 Q d and 1.2 Q d , the average radial force of the optimized impeller is reduced by 22.4 N, 18.5 N and 13.1 N respectively, and the average axial force is reduced by 36.7 N, 30.2 N and 27.3 N compared with the original scheme. It indicated that the optimization effect of mine drainage pump is obvious. Through the analysis of the characteristics of the internal flow field, it is illustrated that the reasonable control of the internal flow law of the pump can effectively improve the hydraulic performance of the pump and improve the stability of the pump operation." @default.
