Common faults and solutions of intelligent box type atmosphere furnace

The intelligent box type atmosphere furnace may encounter various malfunctions during use. Here are some common faults and their solutions:
1. Abnormal temperature
①. Large temperature deviation
Fault manifestation: The actual temperature deviates significantly from the set temperature.
Possible reasons: thermocouple malfunction, temperature control system malfunction, heating element damage, etc.
resolvent:
Check if the thermocouple is damaged or has poor contact, and replace it if necessary.
Check the temperature control system, including controllers, sensors, and other components, to ensure that they are working properly.
Check the heating element for damage or aging, and replace it if necessary.
②. Uneven temperature
Fault manifestation: Uneven temperature distribution inside the furnace.
Possible reasons: uneven distribution of heating elements, damage to insulation materials, internal structural problems in the furnace, etc.
resolvent:
Adjust the distribution of heating elements to ensure uniform temperature inside the furnace.
Check and repair the damaged parts of the insulation material to improve its insulation performance.
Check the internal structure of the furnace to ensure that there are no foreign objects or structural defects affecting the temperature distribution.
2. Atmosphere control malfunction
①. The atmosphere gas cannot be introduced or the flow rate is unstable
Fault manifestation: The atmosphere gas cannot be introduced normally or the flow rate fluctuates greatly.
Possible reasons: gas pipeline blockage, valve failure, flow meter damage, etc.
resolvent:
Clean up foreign objects in the gas pipeline to ensure unobstructed gas flow.
Check if the valve is damaged or blocked, and replace or clean it if necessary.
Check and calibrate the flow meter to ensure accurate measurement.
②. The purity of the atmosphere does not meet the standard
Fault manifestation: The purity of the atmosphere is lower than the set requirements.
Possible reasons: gas source issues, gas purification device failure, etc.
resolvent:
Check the quality of the gas source to ensure that the purity of the gas provided meets the requirements.
Check and maintain the gas purification device to ensure its normal operation.
3. Vacuum system malfunction
Unable to achieve the set vacuum degree
Fault manifestation: The vacuum degree is lower than the set value.
Possible reasons: vacuum pump malfunction, aging and leaking seals, loose pipeline connections, etc.
resolvent:
Check if the vacuum pump is working properly and repair or replace it if necessary.
Check and replace aging seals to ensure good system sealing.
Check and tighten the pipeline connections to prevent air leakage.
4. Electrical malfunction
The power cannot be connected or the device suddenly loses power
Fault manifestation: The device cannot start or suddenly loses power during operation.
Possible reasons: power cord damage, power switch malfunction, circuit short circuit, etc.
resolvent:
Check if the power cord is intact and replace it if necessary.
Check if the power switch is damaged and replace it if necessary.
Check if the circuit is short circuited and eliminate the short circuit fault.
5. Control system malfunction
The program cannot run normally or the control parameter settings are invalid
Fault manifestation: The control system shows a fault prompt or cannot operate according to the set parameters.
Possible reasons: Control software errors, controller hardware failures, etc.
resolvent:
Restart the control system and check if it can be restored to normal.
Check if the control software has been updated to the latest version and update it if necessary.
Check if the controller hardware is damaged and repair or replace it if necessary.
6. Mechanical malfunction
The furnace door cannot be closed or opened normally
Fault manifestation: The furnace door is not tightly closed or difficult to open.
Possible reasons: furnace door deformation, door lock malfunction, damaged transmission mechanism, etc.
resolvent:
Check if the furnace door is deformed and correct or replace it if necessary.
Check if the door lock is damaged or stuck, and replace or repair it if necessary.
Check if the transmission mechanism is damaged and repair or replace it if necessary.
7. Alarm system malfunction
Alarm failure when abnormal situations occur
Fault manifestation: The equipment did not issue an alarm signal under abnormal conditions.
Possible reasons: sensor malfunction, alarm circuit issues, etc.
resolvent:
Check if the sensor is damaged or malfunctioning, and replace it if necessary.
Check if the alarm circuit is connected correctly and working properly, and repair it if necessary.
In summary, common faults in intelligent box type atmosphere furnaces involve multiple aspects such as temperature, atmosphere control, vacuum system, electrical, control system, mechanical, and alarm system. When solving these faults, it is necessary to investigate and repair them one by one based on specific symptoms. At the same time, regular maintenance and upkeep of equipment is also an important measure to prevent malfunctions from occurring.
