根据蒲石河抽水蓄能电站的运行条件，为3种机组转速分别设计了水力流道，并计算分析了转轮内的流速和压力分布．根据泥沙磨损试验结果，结合典型电（泵）站的实际磨损规律，对3种转速下机组可能的磨损程度和大修周期进行了初步预估．在设计院提供的泥沙条件下，大修周期均可达到7年．此外，根据磨损情况和大修周期，对3种转速下的电站综合技术经济指标进行了对比分析论证．结果表明，低转速方案大修周期长，空化性能较好，但工程投资较大，不宜选用；高转速方案大修周期短，但效率指标较高，工程投资也较小．具体选择还要根据电站要求的设计水平，机组运行的稳定性问题等综合比较．
According to the operating conditions of Pushihe Pumped Storage Power Station, the hydraulic runners were designed respectively for the three types of unit rotational speeds, and the flow velocity and pressure distribution in the runner were calculated and analyzed. According to the results of sediment abrasion test and the actual wear rules of typical electric pumping stations, the possible degree of wear and the overhaul cycle of the three kinds of turbines are preliminarily estimated. Sediment provided in the design institute conditions, overhaul cycle can reach 7 years. In addition, according to the wear status and the overhaul cycle, the comprehensive technical and economic indexes of power station under three kinds of speed are contrastively analyzed. The results show that the low speed program has a long overhaul period and good cavitation performance, but the project investment is large and should not be used. The overhaul period of high speed program is short, but the efficiency index is high, and the project investment is also small. The specific choice should also be based on the level of design requirements of the power plant, the stability of the unit operation and other comprehensive comparison.
