1. Material preparation
Before replacing the lower thermocouple of the glass tempering furnace, the following tools and materials need to be prepared:
1.1. Wrench
1.2. Wire scissors
1.3. Insulation tape
1.4. Thermocouples
1.5. Fuses
1.6. Thermocouple instruction manual
2. Remove the old damaged thermocouple(s)
2.1. First, turn off the power of the glass tempering furnace, remove the upper cover of the glass tempering furnace, and locate the thermocouple position.
2.2. Use a hex wrench to remove the thermocouple fixing screw. If the screw is very tight, some lubricating oil can be used.
2.3. Disconnect the two wires of the faulty glass tempering furnace thermocouple from the furnace body, indicate their connection positions, and pull the damaged thermocouple out of the sleeve;
2.4. Use an electrician to cut the cable connecting the thermocouple, being careful not to cut other parts of the cable.
2.5. Remove the original thermocouple from the furnace and use small pliers or tools to scrape off any residue left by the thermocouple in the furnace.
3. Install new thermocouple(s)
3.1. Check if the new thermocouple model is the same as the original one according to the thermocouple manual, and determine the specifications and installation position of the thermocouple.
3.2. Remove the new thermocouple from the attached protective sleeve and gently insert it into the tempering furnace, taking care not to damage the protective tube of the thermocouple.
3.3. When installing a new thermocouple, straighten the thermocouple element and carefully push it into the sleeve. When pushing in, try to grip the base of the element as much as possible to prevent it from bending. Insert its end into the corresponding temperature measurement hole on the wind plate inside the heating furnace;
3.4. Fix the thermocouple screws and use a hex wrench to tighten the screws, being careful not to break them.
3.5. Connect the cable to the new thermocouple and use an electrician's scissors to cut off the insulation of a single wire at both ends of the cable by 2-3cm, exposing the exposed wire.
3.6. Connect the wires according to the connection diagram in the thermocouple manual, ensuring that the connection is correct and error free.
3.7. Fix the cable connection and be careful not to twist or disconnect the connector when it is tightened.
3.8. Connect the wires of the tempering furnace thermocouple, ensuring that the connection position is consistent with the original installation position;
4. Test if the new thermocouple is working properly
4.1. Reinstall the upper cover of the glass tempering furnace, turn on the power supply of glass the tempering furnace, and ensure its normal operation.
4.2. Use a multimeter or thermometer to test the voltage or temperature output of the new thermocouple to ensure its normal operation.
4.3. Regularly inspect and maintain thermocouples according to their instructions to ensure their long-term normal operation.
In short, replacing the thermocouple of the glass tempering furnace requires attention to safety and careful operation. If you find the replacement process complex or unfamiliar, it is best to seek professional technicians for replacement to avoid improper operation that may cause equipment damage or safety accidents.
5. Common problems and solutions
When the thermocouple is damaged, it may cause the tempering furnace to malfunction. If this situation occurs, the thermocouple should be replaced in a timely manner to ensure the normal operation of the glass tempering furnace.
When replacing a thermocouple, if the cable connection is incorrect, the thermocouple may not function properly. If this situation occurs, the cable connections should be rechecked and ensured to be connected correctly.
When inserting a thermocouple, if the insertion direction is incorrect, the thermocouple may be damaged or unable to function properly. If this situation occurs, the thermocouple should be pulled out and reinserted in the correct direction.
