　　Flange electric heater usage precautions:

　　

　　The component should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be dried in an oven at about 200°C for several hours (or by applying low voltage for several hours) to restore the insulation resistance.

　　

　　If carbon deposits are found on the tube surface, they must be removed before reuse to avoid reducing efficiency or even burning out the component.

　　

　　When melting solid oils such as asphalt and paraffin, the voltage should be reduced first, and then raised to the rated voltage after melting. This prevents concentrated power from reducing the component's service life.

　　

　　1. Flange electric heater fault symptom: Blown fuse

　　

　　Causes: 1. Fuse diameter too small, insufficient capacity;

　　

　　2. Short circuit between power plug and electric heating socket;

　　

　　3. Loose or detached lead tabs or wires of the heating tube causing short circuit;

　　

　　4. Heating tube (core) burned out causing short circuit;

　　

　　5. Accumulated dirt or carbonization in the heating socket causing short circuit.

　　

　　Solutions: 1. Replace with a suitable fuse;

　　

　　2. Repair or replace the power plug or heating socket;

　　

　　3. Reconnect securely;

　　

　　4. Repair or replace;

　　

　　5. Clean dirt, repair or replace parts.

　　

　　2. Flange electric heater fault symptom: For temperature-controlled flange electric heaters, the thermostat malfunctions

　　

　　Causes: 1. The ceramic contact rod of the thermostat is stuck by foreign objects;

　　

　　2. Deformation of the bimetallic strip;

　　

　　3. Fatigue of moving and fixed contacts, loss of elasticity, poor contact;

　　

　　4. Moving and fixed contacts stuck together, unable to open and close;

　　

　　5. Loose fastening screws on the moving and fixed contact plates.

　　

　　Solutions: 1. Remove foreign objects, ensure it can move up and down flexibly by hand;

　　

　　2. Adjust the deformation to restore original shape and elasticity;

　　

　　3. Adjust the angle of the contacts to restore elasticity;

　　

　　4. Grind the contacts; if ineffective, replace with new ones;

　　

　　5. Retighten the screws.

　　

　　3. Flange electric heater fault symptom: Heating tube does not heat

　　

　　Causes: 1. Abnormal power supply or power outage;

　　

　　2. Fuse blown;

　　

　　3. Poor contact between power plug and heating socket, or open circuit in power cord;

　　

　　4. Loose or detached lead tabs or wires of the heating tube (core);

　　

　　5. Heating tube (core) burned out;

　　

　　6. Poor contact or melted/disconnected thermostat contacts.

　　

　　Solutions: 1. Check and restore power supply;

　　

　　2. Replace the fuse;

　　

　　3. Repair or replace the power plug or heating socket, or replace the power cord;

　　

　　4. Reconnect securely;

　　

　　5. Replace the heating tube (core);

　　

　　6. Repair or replace the thermostat.
