热水采暖系统中的膨胀水箱,对热水采暖系统的作用有以下几个方面:1、容纳系统中的水因受热而膨胀的体积,补充系统中水的不足。2、指示系统中的水位,控制系统中的静水压力,对系统起定压作用。为了确保以上的作用实现,一般来说:膨胀水箱的膨胀管接在锅炉房内循环泵前的总回水管上。但是在多年的工作中发现,尽管膨胀管接到了锅炉房内循环泵前的总回水管上,个别采暖系统当循环泵停止工作时,膨胀水箱有溢水现象,极个
The expansion tank in the hot water heating system has the following effects on the hot water heating system: 1. The volume of the water contained in the system due to heat expansion, and the shortage of water in the system. 2. Indicate the water level in the system, control the hydrostatic pressure in the system, and exert constant pressure on the system. In order to ensure the above effects are achieved, in general: the expansion pipe of the expansion tank is connected to the total return pipe in front of the circulation pump in the boiler room. However, during many years of work, it was found that although the expansion pipe was connected to the main return pipe in front of the circulation pump in the boiler room, the expansion tank overflowed in the individual heating system when the circulation pump stopped working.
