原水中途串联增压泵站运行方案研究——以青草沙系统南汇 支线为例

Research on the Operation Scheme of Tandem Booster Pumping Station Midway in Raw Water——Taking Nanhui Branch of Qingcaosha System as an Example

青草沙原水系统南汇支线输水距离长、供水量大,中途设有串联增压泵站。针对中途泵站现阶段单路供电的运行风险,论文研究系统双线独立运行方案的可行性,并提出中途泵站超越管加装单向阀的优化运行方案,保障突发状况下原水输送安全。

The Qingcaosha raw water system is equipped with a series booster pumping station midway in the Nanhui branch line with long distance and large water supply.To address the risk of single power supply in the midway pumping station,the paper studied the feasibility of independent operation of the two lines of the system,and proposed an optimized operation scheme to install a check valve on the overflow pipe of the midway pumping station to ensure the safety of raw water transportation in case of emergency.
