离心泵叶轮主要几何参数与反作用度之间的关系研究
Research on the Relationship Between the Geometric Parameters of Centrifugal Pump Impeller and Reaction Factor
摘要
Abstract
Reaction factor should be considered in the hydraulic design of centrifugal pump impeller due to a great effect on blade shape of the centrifugal pump.The relationship between the geometric parameters of centrifugal pump impeller and reaction factor was built based on the definition of reaction factor;meanwhile a mathematical method was adopted to demonstrate the rela-tionship between reaction factor and blade outlet angle.On this basis,this paper discusses the relationship between the specific speed and reaction factor.The analysis concluded that the reaction factor increases with the increase of the specific speed.Reac-tion factor has a distinct effect on the blade shape.In order to reduce the effect of the choice of incidence angle,a new method was proposed to compute the blade inlet angle in the hydraulic design of centrifugal pump impeller.关键词
