How does the ceramic heater device prevent power failure?
The product quality problems of the electric heating device itself and the poor actual operation of the customer may cause leakage safety accidents. We are here in general:
1. Allow electric heating materials to work under the following standards: a. The air humidity of the gas does not exceed 95%, and there is no flammability or corrosive vapor. b. The operating frequency should not exceed 1.1 times the rated current, and the chassis should be properly grounded. c. Grounding resistance ≥ 1mω dielectric strength: 2kv/1min.
2. The electric heating tube should be fixed, and the area of reasonable heating must be completely infiltrated into the liquid or metal material liquid, and it is forbidden to empty it. When it is found that there is dirt or carbon on the surface of the tube body, it should be cleaned immediately and re-applied to prevent damage to the heat dissipation of the heat pipe and reduce the service life.
3. When heating the gas, the components should be symmetrically arranged in a cross shape, so that the components have an excellent heat pipe heat dissipation standard, and the passing gas can be sufficiently heated.
4. When heating fusible metal or liquid salt, alkali, leaching, paraffin, etc. , The working voltage of the service item should be reduced first, and can only be increased to the rated current after the substance is melted.
5. Take safety precautions into consideration when heating saltpeter to avoid explosions.
6. The wiring components should be placed outside the cable sheath to prevent contact with corrosive, flammable substances and moisture in the body. The transmission line should be able to bear the temperature and heat consumption of a part of the transmission line connection for a long time, and prevent excessive force when tightening the connection screw of the transmission line.
7. Such components should be stored in dry areas. If the ground resistance is less than 1ω due to long-term storage, they can dry it in a drying oven at about 200°C, or increase the temperature according to the reduced working voltage, until the ground resistance is repaired.
8. The magnesium oxide powder at the entrance and exit of the electric heating tube should be maintained at the application site to prevent air pollutants and water from penetrating in order to avoid leakage safety accidents.
