Explosion-proof electric heaters are divided into two categories:

Explosion-proof electric heaters are divided into two categories:

One is called explosion-proof electric heaters for mines, which are mainly used in coal mines and mines where gas and other blasting gases are excellent. The other is called explosion-proof electric heaters for factories, which are mainly used in mines and coal mines. All places. Such as: petroleum, chemical, textile, pharmaceutical, military and other companies, including gas explosion-proof and dust-proof electric heaters.

It is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 degree . It has been widely used in many scientific research and production laboratories, such as aerospace, weapons industry, chemical industry and universities. Particularly suitable for active temperature control, large flow and high temperature combined system and accessory experiments. Electric air heaters have a wide range of applications and can heat any gas. The generated hot air is dry and moisture-free, non-conductive, non-burning, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly ( Temperature control).

Connect the ground wire as required and check whether it is correct; 2. The heating tube insulation is damaged (this can be a question of insulating magnesium oxide powder, or a question about the insulation of the joint);
Check the repair if it still shows such a thing, suggest replacement; 3. The heating tube burns out and the cup is short-circuited;
The heating tube is damaged and replace it with the standard heating tube; 4. Improper cleaning, water hits the terminal of the stainless steel heating tube;
Clean and dry the stainless steel heating tube correctly; 5. The circuit wire falls and collides with the cup;
Check the dropped wires and solder them firmly from the beginning; 6. Electric heating socket or power plug.
