how to use an electric heater

1. Components are allowed to work under the following conditions，how to use an electric heater:

A. Air relative humidity shall not be greater than 95%, and no explosive and corrosive gases.

B. The operating voltage shall not be greater than 1.1 times the rated value, and the housing shall be effectively grounded.

C. insulation resistance 1 m or more Ω dielectric strength: 2 kv / 1 min.

2. The electric heat pipe should be well positioned and fixed. The effective heating area must be immersed in liquid or metal solid, and empty burning is strictly prohibited.

In case of lime scale or carbon deposition on the surface of the tube body, it should be cleaned and reused in time, so as not to affect the heat dissipation and shorten the service life.

3, heating fusible metal or solid saltpeter, alkali, leach, stone wax, etc., should reduce the use of voltage, after the medium melting, can rise to the rated voltage.

4. When heating the air, the elements should be evenly arranged across each other, so that the elements have good heat dissipation conditions, so that the air flowing through can be fully heated.

5. Safety measures should be considered when heating saltpeter to prevent explosion accidents.

6. Wiring parts should be placed outside the insulation layer to avoid contact with corrosive, explosive media and water;

The lead connection shall be able to bear the temperature and heating load of the connection part for a long time, and excessive force shall be avoided when the connection screw is fastened.

7, components should be stored in a dry place, if long-term placed below 1 m Ω insulation resistance, can be in around 200 ℃ oven drying, or lower voltage electric heat, until the insulation resistance.

8. Magnesium oxide powder at the outlet of the electric heat pipe can avoid contamination and water infiltration in the use place and prevent the occurrence of electric leakage accidents.

How to use an electric heater，is very important to use electric heating pipe safely, which can avoid safety accidents and prolong the service life of electric heating pipe
