Based on the stanmary of various methodologies and principles of existing pump type selection for large-scale low head pumping stations, this paper puts forward that the reasonability evaluation model of pump type selection, which has three-class indexes in three aspects: energy performance, reliability and operation stability. Using the Fuzzy complex evaluation method,multi-factor and leveling appraisal is carried out. As a case study, the reasonability of the pump type selection of pumping stations in Jiangsu Province of the East Route of South-to-North Water Diversion Project has been assessed. According to the evaluation results, some improving suggestions have been proposed for the design of pumping stations and the notable effects has been made.%在总结大型低扬程泵站泵型选择不同的方法与原则基础上,提出了泵型选择合理性评价模型,该模型包括能量特性、可靠性和运行稳定性3个方面,分为三级指标,一级3个、二级8个、三级16个.采用模糊综合评判的方法进行多因素、分层评判,并以南水北调东线工程江苏省境内的泵站设计为案例,根据评判结果为这些泵站选型提供改进的指导性建议,取得了良好的效果.
