郑州市港区一水厂输水管线首次向市区回供通水,面临输水管线水锤防护及回供水对市区管网产生水力冲击影响的问题。采用Hammer及Bentley Water GEMS软件构建了水锤模型和管网水力模型,对不同输水工况的管道水力瞬变流以及对市政管网的影响区域进行了模拟计算分析。通过优选通水方案并有效指导首次回供通水方案,以保证管网安全运行。
The water supply line of a waterworks in Minhang District of Zhengzhou Municipality will supply water back to the urban area for the first time and will face the problem of hydraulic impact on the urban pipe network caused by water hammer protection and water supply back to the water supply pipeline. The Hammer and Bentley Water GEMS software are used to construct the water hammer model and the hydraulic model of the pipe network. The hydraulic transient flow of the pipelines under different water conveyance conditions and the influence area of the municipal pipe network are simulated and analyzed. Through the preferred water program and effective guidance for the first time back to the water program to ensure the safe operation of the network.
