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
Combined with engineering examples, the phenomenon that the flow of feed water pump and the diameter of expansion pipe are not matched to make the heating system overpressure is analyzed. It is pointed out that the diameter of expansion pipe should be determined according to the flow of feed water pump, and the flow of feed water pump and the diameter of expansion pipe Estimate table
