摘  要:
针对某泵站输水系统高扬程、小流量特点进行水力过渡过程计算,模拟工程设计和运行中可能出现的水泵事故断电,寻求相关控制调度运行的最佳控制模式,以消除或减弱水泵事故断电对系统供水造成的影响,并通过采取相应经济合理的工程措施,确保供水工程的安全性。分别对多种防护手段在高扬程、小流量的输水系统中的防护效果进行了较深入的研究,通过大量的计算论证从运行安全及调度方便的角度出发研究出最佳防护方式:泵后设置空气罐,对控制有压管线中的水锤压力起到了较好效果并有效地保护了输水系统。

摘  要:
In accordance with the characteristics of high-lift flow water supply project,the possible pump electricity out during the engineering design and operation was simulated,the best control model was searched to erase and decrease the influence caused by electricity out to the water supply system.Reasonable measures were adopted to guarantee the water supply safety.An in-depth study was carried out on the preventive effects of high-lift flow water project,and the best protection model was obtained with a large number of computing and demonstration from safe operation and scheduling convenience.It is found that setting up air vessel after the pump is suitable for the pumping station.
