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.
Nedeni aşağıdaki gibidir:
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. Isıtıcı tüp içerisindeki magnezyum tozu nemden etkilenir.
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. Kuru yanma
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.
Güvenli söz vermenin yolu
1. Yüzey yükünü kontrol edin, alan ciddi su ölçeğine sahip, bir metrelik ısıtıcı eleman güç tasarımı 2kw'ın üzerinde olamaz.
2. Uygun malzemeyi seçmek, anti-Asit ve alkali olan sus304 malzemesini seçmek veya SUS304 artı kaplama kullanmak.
3.Avoid magnesia powder be affeced damp,testing the Insulation resistance
