热网循环水泵与管路特性曲线适应性探讨

On suitability of circulating pump and characteristic curve of heat supply network

通过对供热管网管路特性曲线定义及其阻力特性系数S的分析 ,探讨循环水泵工作点和管网水力工况的变化情况 ,提出在供热负荷相同的前提下 ,循环泵随着管网阻力特性曲线的不同 。

Based upon introduction of characteristics curve of pipes in heat supply network and analysis of characteristics resistance coefficient S the working point of circulating pump and hydraulic conditions are discussed. Author points out that circulating pump should be adjusted according to resistance characteristics curve under same heating load.
