How to solve the problem of air-drying heating of cylindrical heating tube

General problem characteristics of air-drying heating:

 

1. Electric leakage (the phenomenon is that the automatic circuit breaker or leakage protection switch trips, and the electric heating tube cannot be heated)

 

2. There is no fever reaction when electrified (whether the electrode part falls off or has poor contact or is broken at the junction box)

 

3. There are obvious cracks on the surface of the ceramic tube (cracks in the electric heating tube, the tungsten alloy heating wire is broken by a large current, etc.)

 

Solution:

 

1. If the leakage current of the cartridge heating tube is greater than the normal value, it is recommended to communicate with the manufacturer to replace it, so as not to affect the use. For example, if the junction box is in contact with water, use hot air to dry it. If the wire is broken, tape or replace the wire.

 

2. The electric heating tube does not heat up when it is energized, generally because the heating wire inside the electric heating tube is broken by an instantaneous large current impact. In this case, we recommend that the user must strictly abide by the product usage method when using it. , This physically damaged electric heating tube cannot be repaired and can only be replaced; if the line or connector is damaged or loose, it can be reconnected.

 

3. The electric heating tube is broken or damaged and can only be replaced.
