摘要
给出一种水轮机比转速的新方法 ,不仅考虑了比转速随水轮机工作水头而变化的规律 ,而且考虑到水轮机的生产年代和生产厂家的因素 ,从而所得的统计分析比转速ns 公式 ,更符合实际情况 。
A new method for statistical analysis of specific speed of turbine is proposed,in which not only variable of specific speed following working head,but also its production year and factory of water turbine are considered.The obtained specific speed fomaula of statistical analysis is more rational to the selection and production of the turbine.[WX(5KG0,41]
