Main failure problems and solutions of electric heating pipes
The main damages of the electric heating tube are:
1. Leakage (the phenomenon is that the automatic circuit breaker or the leakage protection switch is tripped, and the electric heating tube cannot be heated), which accounts for more than 90% of heater failures
2. No heating (the internal heating wire is burnt or the wire is broken at the junction box)
3. The electric heating tube is cracked or broken (the electric heating tube is cracked, the electric heating tube is corroded and broken, etc.)
Approach:
1. For leakage, confirm the leakage point. If it is the electric heating tube itself, it can be baked in an oven. If the insulation resistance cannot be increased, then the electric heating tube may be replaced. Wrap the broken skin with tape or replace the wire.
2. If the electric heating tube is heated, if the internal wire of the electric heating tube is broken, it cannot be repaired and can only be replaced; such as the circuit or the joint is broken or loose and reconnected.
3. If the electric heating tube is broken or broken, only replace it.
