Admittance Criterion of Pressure Superposition Equipment for Secondary Water Supply and Zoning Method of Pressure Variation in Pipe Network
The criteria for selection of superimposed water supply equipment and zoning of pressure variation in mu-nicipal water supply network were presented.The principle analysis of its important parameters,such as minimum allow-able pressure Hdmin and maximum pressure fluctuation △Hdmax,were carried out.According to this criterion,the munici-pal water supply network can be divided into three zones:stable pressure zone,fluctuating pressure zone and fragile pres-sure zone.Finally,the maximum water use day of the main urban area of west A city in 2022 collected in the GIS and SCADA system of west A city,the maximum water pressure and minimum water pressure of all water supply nodes on the same day were taken as credible data,and the pressure variation zoning map of the water supply network in the main urban area of A city in the west was drawn,which is taken as the reference basis for the selection of pressure superim-posed water supply equipment in the main urban area of A city in the west.
