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.
Årsagen er som følger:
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.Magnesia pulver i varmerøret er påvirket med fugt.
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.Tørbrænding
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.
Måden at love det sikre på
1.Kontrol overfladebelastningen, området har alvorlig vandskala, en meter varmeelementeffekt kan ikke være over 2kw.
2.Vælg det egnede materiale, vælg materialet sus304, som er anti-syre og alkali.eller brug af SUS304 plus coating.
3.Avoid magnesia powder be affeced damp,testing the Insulation resistance
