摘要
根据水力计算原理，分析了双流道双向泵站效率和沈道效率对泵站装置效率的影响；提出了原、模型装置效率换算时仅需考虑沿程损失的比尺效应，并据此推导了新的装星效率换算公式。
According to the hydraulics theorem, the effect of pump effciency and passage effi-ciency on system effcency in dual-direction pumping stations have been analyzed. Only thescale effect of linear loss must be considered when converting the system efficiency from themodel to the prototype, and new conversion formula has been put forward.
