水泵的水轮机特性及其应用

本文论述了水泵的水轮机特性,分析了泵特性与水轮机特性的关系,研究了不同比转速水泵的水轮机特性的特点,提出了用水泵作水轮机进行能量回收和水力发电的选型及其设计参数的计算方法。本文提出的理论分析方法,对于正转抽水、逆转发电的多功能泵站及抽水蓄能电站的机组选型亦有一定的意义。

Turbine Behavior of Pumps and Its Application

This paper discusses the turbine behavior of pumps, analyses the behavior relation between: pump and turbine and studies the characteristic of turbine behavior with varied different specific speed pumps. And a calculative method of type selection as well as design parameter by using pump as turbine to carry out both of energy recovery and hydraulic electrogenerating has been proposed, The theoretical analytic method presented here also poss sses a cortaia degree of significance on the type selection of multipurpose pumping plant unit, which can be used as positive rotation for pumoing and negative for generating as well as that of pumped-storage aggregate.
