供热系统泄漏状况评价

Evaluation of heating system leakage condition

近些年,国内供热系统故障频发,带来的不仅仅是经济损失,还有社会影响。国内热网建设从20世纪90年代开始迅猛发展,许多系统距今已有20年的时间,正处于事故高发期。在管网实际工作状态调研的基础上,通过分析热媒泄漏时管网参数的变化规律,提出基于上传参数的一次网泄漏状况评价体系,并对不同的评价结果给出了相应的建议。

In recent years,there are frequent failures in domestic heating systems. It brings not only economic losses,but also social impacts. The construction of domestic heating network has developed rapidly since the 1990 s. Many systems that have been around for 20 years and are in a high accidental rate period.Based on the investigation of the actual working state of pipe network,it analyzes the variation law of parameters during the heat medium leakage,and proposes a network leakage evaluation system based on the upload parameters. It gives corresponding suggestions for different evaluation results.
