摘　　要：本文在试验研究基础上,用三维流动理论,论述了离心泵入口旋流的特性、产生条件和原因,给出了旋流存在区域。分析了旋流和预旋的内在联系,并对一些问题提出了新的论点。Charactristics, Productive conditions and reasons of the spiral flow at inlet of the centrifugal pump is presented here, based on the theory of three-dimen-sional flow and experimental studies. The internal relationship between the spiral flow and prerotation is analized, and some new viewpoints are proposed.
