摘要
在试验研究的基础上,用三维流动理论,论述了离心泵入口旋流的特性、产生的条件和原因;给出了旋流存在区域;分析了旋流和预旋及反向流的内在联系;并对一些问题提出了新的论点。
Characteristics, formative conditions and causes of the spiral flow at inlet of the centrifugal pump are presented in this paper, based on the theory of three -dimensional flow and experimental studies. The internal relationship between the spiral flow and the prerotation and reverse flow is analyzed, and some new viewpoints are proposed.
