【 摘 要 】

The guide vane of a centrifugal multistage pump mostly determines the hydraulic efficiency of the pump and as a consequence the optimal mode of its operation. In order to increase the pump efficiency, the radial channel guide vane has been optimized. Three geometrical parameters and the number of channels of the guide vane were selected as optimization parameters. Hydraulic efficiency was chosen as a criterion. 128 computational models were obtained by the method of automated parametrized construction. The efficiency parameters were obtained via hydrodynamic modeling. As a result, a significant increase in the pump efficiency was achieved.
