基于微观水力模型的中途增压泵站设置方案分析

Analysis of halfway booster pump station installation based on a microcosmic hydraulic model

针对Z市供水管网存在低压区,不能满足用户正常用水需求的问题,对部分主要的管段进行了改管,增加其输送水能力,然后对主要的阀门进行了调控模拟。在进一步优化管网布局的基础上,在Z市平均供水量和最大设计供水量下,对设置增压泵站进行了模拟分析,并对水厂的运行提出了建议,以降低水厂运行成本,提高供水安全性。

Considering the issues of the low pressure area in water supply network in Z City,which could not satisfy user＇s requirements,part of the main pipe sections were replaced in order to increase the capacity of water distribution.The regulation and simulation of main valves were conducted.The booster pump station installation was simulated and analyzed based on the further optimization of the network distribution,at average water supply capacity and maximum design water supply capacity in Z City.Some suggestions of the waterworks operation were put forward.It could reduce the operational cost of waterworks and improve the water supply security.
