摘要
指出目前管网叠压供水系统存在水泵运行效率低、连续供水可靠性下降等问题,叠压供水设备设计、安装、使用不当都会对供水系统产生不利影响。小型气压罐与叠压供水设备联合工作、不同扬程水泵联合工作可进一步增强节能效果,适当降低叠压供水设备的设置高程、缩短引入管长度、放大引入管直径,可增加系统连续供水的可靠性、减小稳压平衡器的体积。
It was pointed out that there exist some problems in the network pressure-superposed water supply, such as low efficiency of pumps and low reliability of continuous water supply. If the facilities of pressure-superposed water supply are not designed or fixed or operated properly, they may affect water supply system badly. Their combination with small pneumatic tank or pumps with different head can save more energy. By means of lowering the elevation of the facilities, shortening the length of inlet pipe and increasing the diameter of inlet pipe, the reliability of water supply may be improved and the volume of pressure balancer be reduced
