鞍山市经济开发区供水管网漏失模型研究

以鞍山市经济开发区供水管网为主要研究对象,在独立划分居民、非居民区域计量基础上,以日为单位分别测试了居民、非居民的用水规律并分析其特点,借鉴时变化系数概念及居民、非居民曲线的分解与合成,提出了曲线峰值比概念.同时在测试区域内安装模拟漏水设施,在已知漏失水量的情况下得到大量峰值比与管网漏失率数据,以此为依据进行相关性计算,建立了管网漏失数学模型,并根据该区管网漏失管理要求设定了管网漏失报警系数.

Leakage model of water supply network in Anshan Economic and Development Area

As an example of water supply network in Anshan Economic and Development Area, based on resident and non-resident regions＇metering separated, the water use regularity of resident and non-resident was tested by daily data, and their characteristics were analyzed. The concept of curve peak ratio was put forward which refer to hourly variation coefficient concept and the separation and combination of resident and non-resident curve. Meanwhile, the simulated leakage equipment was installed in the test area. The large peak value ratio and network leakage rate data were obtained under the condition of known leakage. The network leakage mathematic model was established based on the relative calculation. The network leakage alarm coefficient was set up based on leakage management requirements in this area.
