【 摘 要 】

Various studies show that the centrifugal multistage pump guide vanegreatly determines the hydraulic efficiency of the pump and, as a result, the optimal mode of its operation. In order to increase the pump efficiency, the radial guide vane with a no-blade transfer channelwas optimized. Three geometrical parameters and the number of channels of the guide vanewere chosen as optimization parameters; the hydraulic efficiency was the optimization criterion. 128 computational models were made, and the efficiency values at the operating point were obtained by the method of hydrodynamic modeling. As a result, significant increase in the pump efficiency was achieved.
