When heating the boiler, the boiler electric heater element will sometimes burst. If the leakage protection is not in place, accidents are likely to occur. So many people want to know why the boiler heater element will burst open, and how to avoid it.
Důvod je následující:
1.The water scale on the surface of the boiler heater element is so much,the heat can not be transfer from electric in time,after a long time, the surface of the boiler heater element will burn out, and even the tube will burst.
2. Hořčíkový prášek v trubici ohřívače je ovlivněn vlhkostí.
Magnesium oxide powder has a hygroscopic property. When the boiler heater element is placed in a humid environment for a long time, it may absorb moisture from the pipe mouth.
Or some irregular manufacturers did not dehumidify magnesium powder in the production. At this time, the electric heating tube of the boiler is energized,the moisture in the tube will be heated and become gas. Due to the effect of thermal expansion and cold contraction, the electric heating tube of the boiler will burst open.
3. Suché pálení
The the boiler heater element is designed in accordance with the power standard of the heating liquid when heating , so when the heating liquid leaks out of the liquid and appears dry burning, the electric heating pipe of the boiler will also burst because the surface temperature is too high.
Způsob, jak slíbit bezpečí
1.Ovládejte povrchové zatížení, oblast má vážný vodní kámen, výkon jednoho metru topného prvku nemůže být vyšší než 2kw.
2. Výběr vhodného materiálu, výběr materiálu sus304, který je anti-kyselinový a zásaditý. nebo použití povlaku SUS304 plus.
3.Avoid magnesia powder be affeced damp,testing the Insulation resistance
