摘要
目前,供水企业在统计管网暗漏水量时所使用方法和计算公式各异,相同漏点估算出的暗漏流量差异较大,不便于供水企业之间横向比较和分析研究。通过选取国内供水企业常用的六种暗漏流量估算公式,分别解析了其相关影响因素;同时对比了国外暗漏经验公式,分析相互之间的差异。在此基础上,提出了建议的暗漏流量估算公式,为漏损控制管理提供参考和借鉴。
At present, different methods and formulas are used to estimate unreported bursts leakage in the water distribution networks by water supply enterprises. Water losses estimated from the similar unreported leakage are quite different, which is not easy to compare and analyze. Six kinds of formula are used to calculate the flow rate of unreported bursts in the domestic water supply enterprises, resolving related influential factors, respectively. Comparing to the foreign formulas, differences between each other are analyzed, simultaneously. Based on this, a recommended formula to estimate unreported leakage flow is given, which may provide references for leakage control and management.
