Teach you how to safely use electric heating tubes

Nowadays, electric heating tubes play an indispensable role in our daily lives, and we are paying more and more attention to the safe use of electric heating tubes. If we do not abide by the precautions for safe use of electric heating tubes, it can easily lead to some safety accidents and damage our personal safety. How to safely use electric heating tubes? Below, Wolong has summarized the following precautions for us.

1. Electric heating tubes should be operated under the following conditions: A. The relative humidity of the air should not exceed 95%, and there should be no explosive or corrosive gases. B. The homework voltage should not exceed 1.1 times the additional value, and the casing should be effectively grounded. C. Insulation resistance ≥ 1M Ω, dielectric strength: 2KV/1min. If the operating environment does not meet the above requirements, please stop using the electric heating tube.

2. Electric heating tubes should be properly positioned and fixed, and all useful heating areas must be immersed in liquids or metal solids, and empty burning is prohibited. When scale or carbon deposits are found on the surface of the pipe, they should be promptly removed and reused to avoid affecting heat dissipation and shortening the service life.

3. When heating fusible metals or solid nitrates, alkalis, drains, paraffin, etc., the operating voltage should be lowered first, and only after the medium melts can the additional voltage be raised.

4. When heating the air, the components should be evenly arranged and crossed to provide excellent heat dissipation conditions for the electric heating tube, allowing the flowing air to be fully heated.

5. When heating nitrate, safety measures should be considered to avoid explosion accidents.

6. Wiring should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture; The lead wire should be able to withstand the temperature and heating load of the wiring for a long time, and excessive force should be avoided when tightening the wiring screws.

7. Electric heating tubes should be stored in dry places. If the insulation resistance is lower than 1M Ω due to long-term storage, they can be dried in an oven arranged at 200 ℃ or heated by lowering the voltage until the insulation resistance is restored.

8. The magnesium oxide powder at the outlet of the electric heating tube should be kept away from pollutants and moisture in the application area to prevent the occurrence of leakage accidents.

1. The electric heating tube should be correctly installed with a plug, and it is strictly prohibited to directly insert the wire head into the socket, otherwise it may short circuit and cause a fire;

2. The user must disconnect the power supply of the device when leaving;

3. It is strictly prohibited to place energized electric heating pipes on or near flammable materials;
