How to deal with the malfunction of industrial electric heating tubes

Industrial electric heating tube is a common heating element in electrical components, which can convert electrical energy into thermal energy. Because it is cheap, easy to use and install, and widely used in various heating situations, what should we do if there is a malfunction?

Here are several common faults and their solutions that we have summarized:

Fault 1: No heating

Fault analysis: Abnormal power supply or power outage; The fuse has blown; Poor contact between the power cord plug and the power socket or open circuit in the power cord wire; Short circuit caused by the detachment of inserts or leads in industrial electric heating tubes; Industrial electric heating tubes burned out; Poor contact or melting detachment of the temperature controller contacts.

Solution: Use after normal power supply; Replace fuses of the same model; Repair or replace; Re weld firmly; Replace industrial electric heating pipes with the same specifications; Repair or replace.

Fault 2: Blown fuse

Fault analysis: The fuse diameter is too small and the capacity is insufficient; Short circuit between power cord plug and power socket; Short circuit caused by the detachment of inserts or leads in industrial electric heating tubes; Burning or short circuit caused by industrial electric heating tubes (resistance wires); The accumulation of dirt or carbonization in the electric socket can cause a short circuit.

Solution: Replace the appropriate fuse; Repair or replace the power plug or socket; Reconnect firmly; Repair or replace; Clean up dirt, repair or replace parts.

Fault 3: Temperature controller malfunction

Fault analysis: The ceramic contact rod of the temperature controller is stuck by a foreign object; Thermal bimetallic deformation; Fatigue and loss of elasticity of dynamic and static contact points; The dynamic and static contacts are stuck and cannot be opened or closed; The fastening screws of the dynamic and static contact plates are loose.

Method of handling: Remove foreign objects and move up and down flexibly by pressing with your hand; Adjust the deformation amount, restore the original state and elasticity; Adjust the angle of the contact point to restore its elasticity; Repair the contact points and replace them with new ones if there is no effect; Tighten again.

Fault 4: Leakage

Fault analysis: Connect the ground wire properly; Too much dirt on the electric heating socket or power plug; The circuit wire falls off and collides with the cup body; Insulation damage of industrial electric heating tubes (electric heating wires); Burnout of industrial electric heating tube (electric heating wire) and short circuit of cup body; Improper cleaning and entry into the junction box.

Solution: Connect the grounding wire as required; Clean and dry the product; Check for loose wires and re weld them firmly; Repair or replace; Replace industrial electric heating pipes of the same specification; Correct change to cleaning and drying treatment.
