补给水泵流量与膨胀管管径对供暖系统运行压力的影响 【英文篇名】 Influences of make up water pump flow and expansion pipe size upon operating pressure of the hot water heating system 【作者中文名】 渠谦; 【作者英文名】 By Qu Qian ★; 【作者单位】 中国建筑技术研究院; 【文献出处】 暖通空调, HV 膨胀管; 补水; 静压; 【英文关键词】 open expansion tank; expansion pipe; make up water; static pressure; 【摘要】 结合工程实例 ,分析了补给水泵流量及膨胀管管径不匹配使供暖系统超压运行的现象 ,指出膨胀管管径应根据补给水泵流量来确定 ,给出了补给水泵流量和膨胀管管径的估算表 【英文摘要】 Analyses according to experience from actual projects the problem of over pressure operating of a heating system due to mismatch of make up water pump flow and the diameter of expansion pipe. Points out that the expansion pipe should be sized according to the flow of the make up water pump and provides tabulated data for estimation.
