Problems encountered in the use of electric heating tubes and solutions

1. Defect phenomenon: The temperature controller fails

Cause of occurrence:
1. The porcelain contact rod of the temperature controller is stuck by a foreign body;
2, hot bimetal sheet deformation;
3, dynamic and static contact fatigue, loss of elasticity, poor contact;
4, dynamic and static contacts stick to death, can not open and close;
5, the dynamic and static contact plate fastening screws loose

Treatment method:
1, remove foreign bodies, hand press can move up and down;
2, adjust the deformation, restore the original state and elasticity;
3, adjust the Angle of the contact to restore its elasticity;
4, grinding contact, if there is no effect to replace new products;
5. Tighten from the beginning;

Second, defect phenomenon: no heat

Cause of occurrence:
1. Abnormal power supply or power failure;
2, the fuse has blown;
3. The power cord plug is in poor contact with the electric socket, or the power cord conductor is disconnected;
4, heating tube (core) lead or lead drop;
5, heating tube (core) burning;
6, the temperature controller contact is poor contact or melting off

Treatment method:
1. Use after normal power supply;
2, replace the same type of fuse;
3. Repair or replace;
4, head welding firmly;
5, replace the same standard electric heat pipe (core);
6. Repair or replace

Third, defect phenomenon: leakage

Cause of occurrence:
1, not connected to the ground;
2, electric socket or power plug dirt too much;
3. The circuit wire falls and collides with the cup body;
4, electric heat pipe (core) insulation damage;
5, the electric heat pipe (core) is burned out and the cup body short circuit;
6, improper cleaning, water road into the cup

Treatment method:
1. Connect the ground wire as required;
2. Monotonous treatment after cleaning;
3, check the dropped wire, head welding;
4. Repair or replace;
5, replace the same standard electric heat pipe (core);
6, correct cleaning, monotonous treatment

Four, the defect phenomenon: blown fuse

Cause of occurrence:
1, the diameter of the fuse is too small, the capacity is short;
2. Short circuit between power cord plug and electric socket;
3. The primer or lead of the electric heat pipe falls and causes short circuit;
4, electric heat pipe (core) incineration caused by short circuit;
5, electric socket accumulation of dirt or carbonization caused short circuit

Treatment method:
1, replace the appropriate fuse;
2, repair or replace the power plug or electric socket;
3, the head firmly;
