摘要
对各类二次供水系统模式进行了分析研究。由于技术与管理的因素,传统的增压设备和高位水池(箱)联合供水与变频调速供水,水质较差,且未能利用市政管网压力,存在能量浪费现象。罐式无负压供水能够有效地利用供水管网压力,节约能耗,但供水可靠性较低;箱式无负压供水部分利用管网压力,供水可靠性高,能耗适中。
Different secondary water system modes are analyzed and researched in this paper.According to the factors of technology and management,the water quality is not ideal by means of joint water supply of traditional supercharging equipment and high-level pool(trunk) and frequency control water supply and these water supply modes cannot take advantage of municipal pipeline network pressure resulting in energy waste.Tank no negative pressure water supply can use water supply pipeline pressure network effectively and can save energy consumption,but the reliability of this mode is lower;box no negative pressure water supply can use pipeline network pressure partially with high reliability of water supply and suitable energy consumption.
