旋涡泵内部流动分析及水力设计
Interior Flow Analysis and Hydraulic Design Method of Vortex Pump
摘要
Abstract
By the friction and centrifugal force acting principle,the flow process and the reasons for the energy loss in vortex pump were explained. With an analysis of the main technical specifications about hydraulic model for five typical vortex pump, those empirical formula like impeller vane number Z,impeller diameter D,blade width b,the flow channel area A,diameter coeffi-cient ε,width coefficientβand efflux coefficientλwere deduced. By analyzing the mechanical,volume and flow loss,the calcula-tion of mechanical efficiency ηm ,volumetric efficiency ηv and hydraulic efficiency ηh were elaborated. The case of a self-priming vortex pump (25WZB1. 5-25-0. 75) developed proved that such methods are effective.关键词
