electric heating pipe matters needing attention

1. Components are allowed to work under the following conditions:

(1) The relative humidity of the air is not more than 95%;

(2) The working voltage is not more than 1.1 times the rated value, and the outer casing should be effectively grounded.

2. When the heating medium is a liquid, the effective length of the element (H1 or H2) must be completely immersed in the liquid.

3. Components that heat liquids must not be used to heat gases or solids.

4. For heating liquid components, if there is scale or charcoal on the surface of the pipe, it should be cleaned before use, so as not to affect the service life of the components and reduce the thermal efficiency.

5. When smelting light metal or nitrate salt, alkali, asphalt, paraffin, etc., it is heated when it is solid. It should be started by depressurization. After the solid heating medium is completely melted, it can rise to the rated voltage.

6. Safety measures should be taken when heating nitrate salt to prevent explosion accidents.

7. The component wiring part should be placed on the insulation layer and outside the heating room to avoid contact with corrosive and explosive gases. The outlet end must be kept dry and clean to avoid flashover or short circuit. Do not use excessive force when wiring.

8, the end of the component may overflow a small amount of paste, this is the sealing material, does not affect the use, after the power is off, the spill can be cleaned.

9. The components should be stored in a room where air circulation, relative humidity is not more than 85%, and no corrosive gas.

10. After the component has been used for a long time and is not used for a long time, when the cold insulation resistance is lower than 1 megohm, the component can be baked in a drying oven with a temperature of about 200 degrees, or the voltage can be directly heated to remove moisture. Until it returns to normal.
