What problems should be paid attention to during the operation of the vacuum hot water boiler?

The inside of the vacuum hot water boiler is a vacuum negative pressure environment, and there is basically no risk of outward explosion. The safety factor is very high. It is mostly used in hotels, residential quarters, office buildings, shopping malls and other environments for heating and sanitary hot water. Heating and other fields. Since the pressure in the boiler body is required to always be in vacuum when working, the heat exchange rate and utilization rate are high, and the user frequency is also high.

However, Zhengzhou Fangkuai Boiler Factory still wants to remind you that in order to better protect the boiler body and ensure the safe use of the boiler, the following aspects should be paid attention to during the operation of the vacuum hot water boiler:

1. Before starting the operation of the vacuum hot water boiler, the gas pressure of the boiler must be checked to ensure that its pressure is normal. If the static pressure is only 6 kPa, it should be noted that only a small fire can be maintained, because under a pressure of 6 kPa, the large fire may be extinguished due to insufficient pressure.

2. When using a vacuum hot water boiler, pay attention to the pressure and temperature of the domestic hot water and heating medium water, and make sure that the pipeline valve is opened to prevent the inlet and outlet water valves of any heat transfer branch from closing, because during use, due to thermal expansion And the principle of cold shrinkage, the pressure will far exceed the rated working range. This caused major accidents such as pipeline explosions and boiler scrap.

3. Under various normal working conditions of the vacuum hot water boiler, pay attention to the operation of the water pump, carefully observe the outlet pressure of the water pump and its sound, and turn on the boiler control power supply when it works normally.

4. When the vacuum hot water boiler is running, pay attention to setting the relevant parameters on the display screen to ensure that the middle water temperature, the outlet water control temperature, the flame conversion temperature and the temperature difference can meet the operating requirements.
