多级泵站是一个包括各级泵站及泵站内各种设施的复杂系统,系统内各个泵站的老化直接影响整个泵站系统的正常运行.采用单元化方法将多级泵站系统单元化,引入泵站老化评价指标,建立了多级泵站老化的模糊评价模式,并对甘肃省景泰高扬程提水灌区多级泵站系统进行分析,提出了评价多级泵站老化程度的排序方法. Multi-stage pumping station is a complicated system including all kinds of pumping stations and pumping stations in all levels, the aging of each pumping station in the system directly affects the normal operation of the whole pumping station system.Using the unitization method to unitize the multi-stage pumping station system , Introduces the evaluation index of aging of pumping station, establishes the fuzzy evaluation mode of aging of multi-stage pumping station, analyzes the multi-stage pumping station system of Jingtai high lift pumping and water pumping station in Gansu Province, and puts forward a ranking method to evaluate the aging degree of multi-pumping station .
