利用分布式变频泵系统提高热网的供热能力

Improving Heating Capacity of Heat-supply Network by Distributed Variable-frequency Pump System

结合工程实例,对于新增负荷导致末端热用户资用压头不足情况,提出采用增设回水加压泵站或分布式变频泵的解决方案,后者是提高供热能力和降低能耗的有效方法。

Aimed at the insufficient available pressure head caused by newly added load, the solu- tion schemes of adding return water booster pump station or distributed variable-frequency pump are put forward with an engineering example, and the latter is the effective method to improve heating capacity and reduce energy consumption.
