Common faults and solutions for customized tempering furnaces

The common faults and solutions for customized tempering furnaces are as follows:

1. Heating related faults
Uneven heating or partial area without heating
Reason: The heating element works for a long time and is susceptible to damage due to factors such as high temperature and oxidation.
Solution: Use a thermal imager or infrared thermometer to check if the heating element temperature is uniform. If damage is found, replace the heating element with a qualified one in a timely manner.
The actual temperature does not match the set temperature
Reason: Temperature sensor malfunction, controller malfunction, furnace structure problem, or control system failure, etc.
Solution: Check if the temperature sensor is working properly and replace it promptly if it is damaged; Check if the controller is functioning properly. If there is a malfunction, repair or replace it according to the specific situation; Check if the furnace structure is intact, and if there is any deformation or air leakage, make corresponding repairs.

2. Furnace related faults
Cracks appear in the furnace
Reason: The furnace material has been working at high temperatures for a long time or has been damaged due to improper operation during use.
Solution: After the furnace cracks, it should be immediately stopped from use and professional personnel should be contacted for repair or replacement. Regularly inspect and maintain the furnace to avoid damage caused by long-term high-temperature work.
The vacuum degree inside the furnace cannot meet the requirements
Reason: Poor sealing of the vacuum system, decreased performance of the pump unit, or pipeline blockage.
Solution: Check the sealing of the vacuum system and repair any leaks in a timely manner; Check the performance of the pump unit, and if the performance decreases, maintenance or replacement is required; Clean up pipeline blockages and keep the pipeline unobstructed.

3. Electrical related faults
The device cannot start
Reason: Power line malfunction, controller malfunction, etc.
Solution: Check if the power line is connected properly, and repair it promptly if there is any open or short circuit; Check if the controller is working properly, and repair or replace it if there is a malfunction.
No display or abnormal display on the screen
Reason: Damaged display screen or controller malfunction.
Solution: Check if the display screen and controller are working properly, and repair or replace them if there is a malfunction.

4. Other faults
Furnace smoking
Reason: It may be caused by short circuits between the wiring terminals and the tempering furnace casing, poor insulation at the fan motor shaft or lead terminals, and other reasons.
Solution: Check and repair short circuits or poor insulation to ensure stable and reliable electrical performance of the equipment.
Tempering or de ignition
Reason: The velocity of the mixture of gas fuel and premixed air flowing out of the flame hole does not match the flame propagation speed.
Solution: Increasing the fuel pressure to ensure the spraying speed of the mixture, or cleaning the nozzle in a timely manner to reduce the air content in the mixture to reduce the flame combustion speed, can effectively avoid the occurrence of backfire. Immediate reduction of fuel and atomization steam volume and adjustment of air volume should be carried out to ensure that the flame is close to the flame hole when it is found to be misfiring. If there is no effect, stop the nozzle and inspect and repair the burner.
