General problem characteristics of air dry heating:
1. Leakage (the phenomenon is that the automatic circuit breaker or the leakage protection switch trips, and the electric heating tube cannot be heated)
2. There is no heating reaction when electrified (whether the electrode part falls off or has poor contact or is broken at the terminal box)
3. There are obvious cracks on the surface of the ceramic tube (cracks in the electric heating tube, tungsten alloy heating wire is broken by a large current, etc.)
Solution:
1. If the leakage current of the cartridge heating tube is larger than the conventional value, we recommend to communicate with the manufacturer to replace it so as not to affect the use. For example, if the terminal box contact with water, use hot air to dry it. And if the wire is broken, wrap it with tape or replace the wire .
2. The electric heating tube does not generate heat when it is energized, generally because the heating wire inside the heating tube is broken by the instantaneous high current impact. In this case, we recommend that the user must strictly abide by the use method of the product when using it. , This kind of electric heating tube that is physically damaged cannot be repaired and can only be replaced; if the line or connector is broken or loose, it can be reconnected.
3. For cracked or broken electric heating tube, only replace it.
