摘　　要：泵站多台水泵同时并联运行时,水泵实际效率通常会低于水泵设计效率,实际电机功率也会提高。本文根据东台新抽水站实际运行时的流量及电动机功率,计算分析泵站在不同运行工况下的水泵运行效率。通过与模型泵装置性能对比,发现泵站在多台水泵同时运行时,水泵效率显著降低。水泵并联运行时造成的水流紊乱及额外水力损失并未在水机设计选型时得到体现,但实际运行中却不能忽视。本文的分析结果可为其他类似工程在水机设计选型或是工程运行管理时提供参考。When many water pumps in a pump station run in parallel at the same time,the actual pump efficiency is usually lower than the designed efficiency of the pumps,and the actual motor power will also be improved.The water pump operation efficiency of the pump stations under different operation stations is calculated and analyzed based on the flow and motor power of Dongtaixin Pump Station during actual operation,the water pump operation efficiency of the pump station under different operation conditions is calculated and analyzed in the paper.Compared with the performance of the model pump device,it is found that the pump efficiency is decreased significantly when many pumps are operated at the same time.Water flow disturbance and extra hydraulic loss caused by parallel operation of water pumps are not reflected in the design and selection of water pumps,but these problems can not be ignored in practical operation.The analysis results of the paper can provide reference for other similar projects in the design and selection of water dispenser or project operation management.
