用EPANET确定供水管网的最不利配水点

Using EPANET to Determine the Most Unfavorable Point of the Water Distribution Network

最不利配水点即供水管网用水压力最难满足的点。要进行供水管网水力计算并满足供水要求,首先要确定给水系统中最不利配水点的位置及相应的计算管路,最不利配水点的确定是给水管网系统设计的重要步骤,推求泵站扬程前首先应确定最不利配水点。在进行水力分析前无法确定最不利配水点的位置,从最不利配水点在给水管网中的重要性出发,选取一个有清水池和一个水塔的给水管网系统案例,总结了应用EPANET软件确定给水管网中最不利配水点的方法。

The most unfavorable point of the water supply pipe network is the point where the water pressure is the most difficult to satisfy, For water supply pipe network hydraulic calculation and to meet the requirements of water demand, determining the most unfavorable water distribution point in the water supply system is the most important step, followed by the calculation of the relative lines. Therefore, determination of the most unfavorable water distribution point is an important process in the design of the water supply pipe network system. It should finished before calculating the pump station water head. But the point cannot be determined before the hydraulic analysis. An example containing a clean water tank and a water tower in water supply pipe network system, the methods of applying the EPANET software to determine the most unfavorable water distribution point were summarized.
