Common problems in the application and storage of electric heating tube

1. The electric heating tube should be stored in a dry place. If it is placed for a long time, the grounding resistance is less than 1m Ω The heater can be powered on by reducing the working voltage until the grounding resistance is repaired.

2. The electric heating tube should be accurately positioned and fixed. In the reasonable scalding area, all liquid or metal materials must be infiltrated into the solid state. No empty burning is allowed. If dirt or carbon deposit is found on the surface of the tube, it should be removed immediately and reused to avoid affecting the heat dissipation of the heat pipe and reducing the service life.

3. When heating fusible metal or solid nitrate, alkali, leaching, stone wax, etc., the working voltage of the electric heating tube should be reduced first, and the rated current can be raised only after the material is melted.

4. MgO powder at the end of heating pipe can prevent air pollutants and water from penetrating into the application site, and avoid power loss accidents.

5. When heating the gas, the components should be arranged in a cross symmetrical order, so that the components have excellent heat pipe heat dissipation standards, and the air passing through can be heated sufficiently by the water heater.

6. Part of the electric heating pipe wiring should be placed outside the insulation layer to prevent contact with corrosion, combustible substances and moisture; Lead wiring should also bear the temperature and heating load of a part of the wiring for a long time, and the wiring screw should be tightened to prevent excessive force.

7. Safety precautions should be considered when heating nitrate to prevent explosion.
