What faults may occur during the use of high-temperature vacuum furnaces? How should we handle it?

The possible faults and their solutions during the use of high-temperature vacuum furnaces mainly include the following points:

1. Insufficient vacuum degree
Possible reasons:
Vacuum pump malfunction.
The vacuum seal is aging or damaged.
leak.
The vacuum gauge display is inaccurate.

Handling method:
Check the operation of the vacuum pump and clean or replace it if necessary.
Check and replace aging seals.
Use a vacuum leak detector or other methods to inspect and repair the leak points.
Proofread the vacuum gauge to ensure its accuracy.

2. Abnormal temperature
Possible reasons:
The heating element is damaged.
Control system malfunction.
Thermocouple malfunction.

Handling method:
Check the connection and resistance of the heating element, repair or replace damaged heating elements.
Check and calibrate the control system to ensure its proper functioning.
Replace or reconnect the faulty thermocouple.

3. Cooling system malfunction
Possible reasons:
Insufficient supply of cooling water.
The cooling system is blocked.

Handling method:
Check if the cooling water pipeline is unobstructed to ensure sufficient cooling water supply.
Clean the blockages in the cooling system.

4. Electrical malfunction
Possible reasons:
Poor contact of power cord.
Relay malfunction.
Controller setting error.

Handling method:
Check the connection of the power cord to ensure good contact.
Replace the faulty relay.
Check the settings of the controller to ensure that the parameter settings are correct.

5. Other faults
High noise: It may be due to wear or breakage of the vacuum pump coupling, and the coupling needs to be replaced.
Vacuum pump fuel injection: It may be due to the detachment of the O-ring of the suction valve, which needs to be re stretched and embedded into the O-ring.
Motor reverse time too long: It may be due to incorrect phase sequence of the power line, and any two-phase power lines (except for the ground line) need to be replaced.

6. Emergency handling measures
In the event of a malfunction in a high-temperature vacuum furnace, the following emergency measures should be taken to ensure the safety of equipment and personnel:
Immediately turn off the total power of the device.
Close the vacuum valves of each pipeline to prevent air from entering the high-temperature vacuum furnace.
If using recycled water for cooling and water supply, a backup water source should be activated.
Transfer the workpiece from the heating chamber to the cooling chamber (if possible) and rapidly cool the components with nitrogen.

7. Preventive measures
To reduce the failure rate of high-temperature vacuum furnaces and extend the service life of equipment, the following preventive measures should be taken:
Regularly maintain and upkeep the equipment, including cleaning the vacuum pump, replacing seals, checking heating elements, etc.
Strictly follow the operating procedures when using equipment to avoid overloading and improper operation.
Provide professional training to operators to enhance their operational skills and safety awareness.

Regular maintenance of the vacuum furnace is also an important means to reduce malfunctions

Overall, there are various types of malfunctions that may occur during the use of high-temperature vacuum furnaces. However, as long as the correct handling methods and preventive measures are taken, the occurrence of malfunctions can be effectively reduced, ensuring the normal operation and safe production of the equipment.Click to learn more Vacuum Furnaces!
