Customers who use heating tubes often encounter short-circuit problems of electric heating tubes, so I will learn with you today. We need to know that the commonly used heating tubes can be divided into: U-shaped heating tubes, flange heating tubes, fin heating tubes, single-ended heating tubes and so on.
The first situation: the electric heating tube blows the resistance wire
Reason: A. Short circuit caused by burning of electric heating tube;
B. The lead or lead of the electric heating tube falls off and causes a short circuit;
C. The diameter of the resistance wire is too small and the capacity is insufficient;
D. Dirt accumulation or carbonization of the electric heating socket causes a short circuit
E. The power cord plug is short-circuited with the electric heating socket;
Solution: A. Replace the heating tube;
B. Re-welding;
C. Replace the suitable resistance wire electric heating tube. According to the research of Yancheng Songtai Technology Department, under normal circumstances, the iron-chromium-aluminum resistance wire can be used.
D. Remove dirt, repair or replace parts
E. Repair or replace the power plug or electric socket;
The second case: the electric heating tube does not generate heat
Reasons: A. For the adjustable temperature control heating tube, the contact of the temperature controller is poorly contacted or melted off.
B. Abnormal power supply or power failure;
C. The resistance wire has been blown;
D. The power cord plug is in poor contact with the electric heating socket, or the power cord wire is disconnected;
E. The electric heating tube has been burned;
F. The lead or lead of the electric heating tube falls off;
Solution: A. The heating tube is not easy to repair, it is recommended to replace it;
B. Use after normal power supply;
C. The heating tube is scrapped, and the resistance wire of the same model shall be re-produced and installed;
D. Check the circuit for repair or replacement;
E. Replace and install the same specification electric heating tube;
F. Re-welding the lead or lead;
The third situation: leakage of electric heating tube
Reason: A. The circuit wire fell off and collided with the cup body;
B. The electric heating tube is burnt out and the cup body is short-circuited;
C. The ground wire is not well connected;
D. There is too much dirt on the electric heating socket or power plug;
E. The insulation of the electric heating tube is damaged;
F. Improper cleaning and moisture leaking into the cup;
Solution: A. Check the disconnected wire and re-solder it firmly;
B. The electric heating tube is damaged and replace the electric heating tube of the same specification;
C. Connect the ground wire as required and check whether it is correct;
D. Clean and dry properly;
E. Check and repair if such an event still occurs, it is recommended to replace it;
F. Clean and dry properly;
