摘要
多级泵正导叶喉部尺寸对泵的性能有重要的影响 ,该文介绍了一种事先给定喉部尺寸以计算正导线其它有关几何参数的方法。
The throat size of the guide vane used in multistage pumps is of importance to p[WT10.,9.75]ump characteristics. The author of this paper presented a new programme in which the throat size is given previously to shape the spiral of the guide vane, aiming at improoing the pump hydraulic efficiency.
