集中供热水系统若干问题分析

Analysis of Issues in Central Heating Water System

通过对几个典型的集中供热系统的问题调查分析,利用水压图分析总结了水系统的“超压”与“不热”的原因,以及解决措施,指出采用微机变频自动补水、超压自动泄水装置可稳定水压,改变恒压点位置来降低动水压线,同时指出流量的不足对系统的影响.

Based on an investigation of the some questions of typical central heating system, according to the water pressure diagram, analyses and summarizes the reasons and resuhs of ＂excess pressure＂ and ＂heating impotence＂ in water system. Points out the methods that apply make-up pumps with frequency control of speed and discharge valve with constant pressure, changed the positions of constant pressure point to lower water pressure diagrams. And points out that the flow is influencing on the water system.
