Precautions for using electric heating element

The use of electric heating element pipe Note:

1, the components allow the following conditions:

 A. Air relative humidity of not more than 95%, non-explosive and corrosive gases.

B. The working voltage should not be greater than 1.1 times the rated value, the shell should be effectively grounded.

C. Insulation resistance ≥ 1MΩ Dielectric strength: 2KV / 1min.


2, electric heating element tube should be positioned fixed, effective heat must be fully immersed in liquid or solid metal, is strictly prohibited air burning. Found that the surface of the pipe body scale or carbon, should be promptly removed and then clean, so as not to affect the heat and shorten the service life.

3, heating fusible metal or solid nitrate, alkali, asphalt, paraffin, etc., should first reduce the use of voltage, until the media is melted, to rise to rated voltage.

4, when the air heating elements should be cross-aligned, so that components have a good heat dissipation, so that the flow of air can be fully heated.

5, heating nitrate should be considered when the security measures to prevent the explosion.

6, the wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, water; lead wires should be able to withstand long-term part of the wiring temperature and heating load, tighten the wiring screws should avoid excessive force.

7, the components should be stored in a dry place, if the insulation resistance placed for a long time less than 1MΩ, can be about 200 ℃ in the oven drying, or reduce the voltage heating, until the restoration of insulation resistance.

8, electric heating pipe outlet of the magnesium oxide powder, in the use of places to avoid contaminants and water infiltration to prevent leakage accidents.
