What are the common faults and solutions of rotary furnaces？

Rotary furnaces, such as rotary tube furnaces, may encounter various common faults during long-term use. Here are some common types of faults and their solutions:
1. Power and circuit faults
Common faults:
The indicator light is not on or flashing.
The power supply is normal but the stove is not working.
resolvent:
Check the power supply: Ensure that the power plug is securely plugged into the socket and the power cord is not damaged.
Check the fuse: Check if the fuse is blown and replace it if necessary.
Check the control circuit: Check whether the control circuit is connected correctly and whether there is a short circuit or open circuit.
Restart the device: Try restarting the furnace to see if it can resume normal operation.
2. Temperature control malfunction
Common faults:
The temperature display is inaccurate.
The temperature cannot reach the expected value or rises slowly.
resolvent:
Check the temperature sensor: Ensure that the temperature sensor is installed correctly, undamaged, and the connection circuit is in good condition.
Calibrate temperature controller: Use a standard thermometer to calibrate the temperature controller to ensure accurate temperature display.
Check the heating element: Check if the heating element is intact and if the power is sufficient. If there is damage or insufficient power, replace it.
Cleaning the hot air duct: Regularly clean the hot air duct to prevent blockage and affect heat transfer efficiency.
3. Mechanical malfunction
Common faults:
The rotating mechanism does not rotate or rotates abnormally.
The furnace door is not tightly sealed or cannot be closed.
resolvent:
Check the motor: Ensure that the motor is running normally without any abnormal sounds or overheating.
Check the transmission components: Check whether the transmission components such as belts, chains, gears, etc. are severely worn, and replace them if necessary.
Adjust the furnace door: Check whether the sealing strip of the furnace door is aging or damaged, and replace it if necessary; Adjust the position of the furnace door to ensure a tight seal.
Lubricating components: Regularly add lubricating oil to the rotating mechanism and transmission components to reduce wear and friction.
4. Gas system malfunction (for furnaces using gas)
Common faults:
Insufficient or unstable gas flow.
Gas leakage.
resolvent:
Check the gas pipeline: Ensure that the gas pipeline is unobstructed, without blockage or leakage.
Adjust gas pressure: Adjust the gas pressure to the appropriate range according to the requirements of the furnace.
Replace flow meter: If the flow meter malfunctions and causes inaccurate flow, a new flow meter needs to be replaced.
Repair leakage point: When a gas leak is found, immediately turn off the gas source and repair the leakage point.
5. Security protection system triggered
Common faults:
Over temperature protection triggered.
Overvoltage protection triggered.
resolvent:
Reduce temperature or pressure: Reduce the furnace temperature or pressure to a safe range according to the prompts of the safety protection system.
Check the protection system: Check if the protection system is set correctly and if there are any false alarms.
Troubleshooting: Identify the source of the fault that triggered the protection system and troubleshoot it.
6. Other faults
Common faults:
Control system software malfunction.
Loose or detached components.
resolvent:
Restart the control system: Try restarting the control system software to see if it can resume normal operation.
Tightening components: Check and tighten loose components to prevent detachment or damage.
Contact the manufacturer or professional maintenance personnel: For complex or difficult to solve faults, contact the furnace manufacturer or professional maintenance personnel for maintenance.
Please note that the above information is for reference only. Specific faults and solutions need to be determined based on the specific model, specifications, and user manual of the furnace. Please be sure to follow the safety operating procedures during the operation to ensure personal and equipment safety.
