Customized atmosphere furnaces may encounter various malfunctions during use. Here are some common malfunctions and their solutions:
1. Heating system malfunction
Fault symptoms: slow heating speed, high temperature, or unstable temperature.
Possible reasons:
Heating element aging, damage or poor contact.
The thermostat is damaged or improperly set.
Power supply voltage fluctuation.
resolvent:
Check the working status of the heating element and replace it promptly if there are any problems.
Check and adjust the settings of the thermostat to ensure accurate temperature control.
Ensure stable power supply voltage, and install a voltage regulator if necessary.
2. Vacuum system malfunction
Fault phenomenon: The vacuum degree cannot reach the preset value or the vacuum degree drops too quickly.
Possible reasons:
The vacuum pump is damaged or its performance has decreased.
The sealing components on the furnace body or pipeline are aging, broken, or improperly installed.
There are gas leakage points inside the furnace, such as pipeline connections, valves, etc.
resolvent:
Check the working status of the vacuum pump and repair or replace it promptly if there are any problems.
Check and replace aging or broken seals to ensure good sealing.
Use leak detection tools to inspect gas leakage points inside the furnace and repair or replace relevant components.
3. Atmosphere control system malfunction
Fault phenomenon: The concentration of the atmosphere inside the furnace deviates significantly from the set value.
Possible reasons:
Gas supply system malfunction.
The flow meter is inaccurate.
Control system malfunction.
resolvent:
Check the gas supply system to ensure stable gas flow and pressure.
Regularly calibrate the flow meter to ensure its accuracy.
Check and repair control system faults.
4. Electrical system malfunction
Fault phenomenon: The device cannot start, the power indicator light is not on, and the control system is unresponsive.
Possible reasons:
Power failure.
Hardware malfunction in the control system.
Control system software malfunction.
resolvent:
Check the power supply status of the power circuit and control system to ensure that the power supply is normal.
Check and replace damaged components inside the control system.
Update or reinstall control system software to ensure software version is compatible with hardware.
5. Other faults
Furnace body leakage:
Possible reasons: aging, cracking, or improper installation of seals at furnace doors, observation windows, and other locations; Loose pipeline connections; The furnace body is damaged.
Solution: Check and replace aging or broken seals; Tighten the pipeline connection; Repair or replace damaged furnace bodies.
Pneumatic valve cannot operate:
Possible cause: malfunction of solenoid valve; Insufficient compressed air pressure; The pneumatic valve itself is damaged.
Solution: Check the working status of the solenoid valve; Ensure that the compressed air pressure meets the working requirements; Replace the damaged pneumatic valve.
6. Preventive measures
To avoid malfunctions in customized atmosphere furnaces, the following preventive measures can be taken:
Regular maintenance: Regularly maintain the vacuum atmosphere furnace, including cleaning, inspection, and replacement of vulnerable parts.
Standardized operation: When using an atmosphere furnace, it is necessary to strictly follow the operating procedures to avoid malfunctions caused by improper operation.
Environmental monitoring: Keep the environment where the equipment is located clean, dry, and dust-free to avoid environmental factors affecting the equipment.
Timely recording: During use, timely recording of the operating status and fault phenomena of the equipment helps to detect and handle faults in a timely manner.
In summary, common faults in customized atmosphere furnaces involve multiple aspects such as heating systems, vacuum systems, atmosphere control systems, and electrical systems. When a malfunction occurs, it should be investigated one by one based on specific phenomena and possible causes, and corresponding solutions should be taken. Meanwhile, by taking preventive measures, the probability of faults occurring can be reduced, ensuring the stable operation of the equipment.
