本文通过实验数据说明局部汽蚀对大轴面角叶片入口边离心轮泵特性的影响,分析局部汽蚀产生的原因以及消除局部汽蚀所应采取的措施,特别对离心轮入口回流区与局部汽蚀之间的关系作了探讨。
In this paper, the influence of local cavitation on the characteristics of centrifugal pump on the entry side of large-angle axial vane is demonstrated by experimental data. The causes of local cavitation and the measures to eliminate local cavitation are analyzed. Especially, The relationship between cavitation was discussed.
