摘要
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。
Based on the summary 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-classindexes 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 staions 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 hasbeen made.
