【摘要】 结合某城市最高日实测用水量变化情况,应用EPANETH软件模拟一天内多时段管网的运行情况。由节点自由水压-管段流速图、各节点自由水压图看出,最高点时确定的管径及水泵在其他时段并不能全部满足节点的压力要求。通过调整个别管段管径,适当提高水泵扬程使各节点的自由水压均满足压力要求。更多还原

【Abstract】 Combined with the highest measured water consumption change in a certain city,this paper expounds how to use EPANETH software to simulate the multi period network operation. The results obtained node free water pressure- pipe flow graph,node free water pressure- pipe segment flow graph and each node free pressure graph,and checked free water pressure and the tower transfer condition. The result also showed that the determinged water pump in the highest point can not meet the requirements of other time pressures. Through repeated adjustment of individual pipe diameter and appropriate increase of the pump head,finally each node satisfies the requirements of free water pressure.更多还原
