热网循环系统中调速水泵的应用与经济分析

The application of adjustable-speed water pump in heating tubing circulating system and its economic analysis

因过去供热系统中循环水泵的流量可调节范围小、耗电量大 ,故对其进行改造势在必行。详细介绍水泵变速的各种调节方式 ,分析了每种调节方式的节能效果 ,确定采用调速水泵可使供热系统无级的变流量运行成为现实。同时还对该种调速方式作了经济评价 。

Because of the little adjusting scope and large power consumption of circulating water pump in heat tubing system the improvement for this system is imperative. In this paper some adjusting ways of water pump variable speeds are introduced in detail. Adopting adjustable speed water pump can realize operation with step less speed adjusting flow for heating system. at the same time the speed adjustable pattern is made economic evaluation. It has obvious benefit.
