目前热水采暖广泛用于工业和民用建筑中。但是由于施工作业人员在热水采暖系统的施工、调整与运行管理方面的经验不足,系统在运行时可能会出现一些故障,影响正常供热。经过多年的现场实践,总结了热水采暖系统几种常见的故障及其排除方法,供大家参考。1.系统回水温度过低产生系统回水温度过低的原因大体有以下几种情况:热源所设置的锅炉不能供给足够是热量,使送水温度达不到设计要求。这时应改造或增设锅炉,提高送水温度;循环水泵的流量小或扬程低,系统热媒
At present, hot water heating is widely used in industrial and civil buildings. However, due to lack of experience in the construction, adjustment, and operation management of the hot water heating system, construction workers may experience some malfunctions during operation and affect normal heating. After years of on-site practice, several common faults and their elimination methods for hot water heating systems have been summarized for your reference. 1. System return water temperature is too low to produce the system return water temperature is too low due to the following general conditions: The heat source is set by the boiler can not supply enough heat, so that the water temperature can not meet the design requirements. At this time, boilers should be reformed or added to increase the temperature of the water supply; the circulation pump has a small flow or low head, and the system heat medium
