严格地说,我国大型泵站设计装置效率并不低,一般均在70%以上,巨型泵站接近80%。但装置经常运行效率普遍较低,不少泵站达不到水电部65%的要求,有的甚至仅有20～30%。让我们总结分析一下已建泵站的运行实践,探讨装置运行效率低的原因。大型泵站设计与运行实践 Strictly speaking, the design efficiency of large-scale pumping station in China is not low, generally above 70%, and the giant pumping station is close to 80%. However, the efficiency of the plant is often low, and many pumping stations can not meet the requirements of the Ministry of Electricity and Water, 65% or even 20% to 30%. Let us summarize and analyze the operational practices of the built pumping stations and discuss the reasons for the low operating efficiency of the devices.
