浅谈比转速初选法在中小型水轮机选型设计中的应用

Discussion on the Application of Preliminary Selection Method With Specific Speed at the Design of Type Selections of Middle and Small Sized Water Turbines

本文根据水轮机相似律,用水轮机的相似判别数——比转速,全面分析适合于该水电站参数的全部已产水轮机转轮,和拟用的各种机组参数的配备组合:从而挑选出几个较优的机型方案,再通过全面的技术经济比较,最后确定出选取的最优机型。

This paper has introduced the application of Preliminary Selection Method With specific speed at the design of type selections of middle and small sized water turbines. According to the similarity principle, all completed runners which are suitable to parameters of middle and small sized water power stations and the coordination of various parameters of all sets have been analyzed with the specific speeds, several better schemes have been gotten and the optimal scheme will be found through entire technical and economical comparision.
