摘要
由于当前供水管网漏失检测主要依靠仪器且缺乏系统的方法,本文通过分析渗漏原因研究供水管网漏失检测技术。以某市住宅小区为例,利用孔口流出量和指数经验确定水流规律,并分析供水管网漏失成因;通过节点流量连续性方程和降压计算方程,建立供水管网水力模型;调整水量系数完成模型参数优化,再利用水力模型完成漏失检测。测试结果表明:对漏失检测技术优化后,小区内供水管网平均漏失率降低到4.446%,有效解决供水管网渗漏问题。
Because the current water supply network leakage detection mainly relies on instruments and lack of systematic methods, the leakage detection technology of water supply network was studied in the paper. Taking a residential area in a city as an example, the water flow law was determined by using the orifice outflow and index experience, and the causes of leakage of the water supply network are analyzed;the hydraulic model of the water supply network is established through the node flow continuity equation and the depressurization calculation equation;the water volume coefficient is adjusted. After completing the optimization of model parameters, the hydraulic model was used to complete the leakage detection. The test results show that after optimizing the leakage detection technology, the average leakage rate of the water supply network in the community reduce to 4.446%, which effectively solves the leakage problem of the water supply network.
