Daily maintenance of vacuum ceramic sintering furnace

The daily maintenance of vacuum ceramic sintering furnace is the key to ensuring its long-term stable operation and extending its service life. Here are some suggestions for daily maintenance of vacuum ceramic sintering furnaces:

1. Cleaning and maintenance
Furnace cleaning:
Clean the furnace body, instruments, and control cabinets daily to keep their surfaces clean and dust-free.
Regularly clean the interior of the vacuum chamber to remove any residue and maintain its cleanliness.
Clean the dust and impurities on the surface of the heating element to improve heating efficiency.
Sealing structure cleaning:
The sealing structure on the furnace body should be cleaned with alcohol or gasoline, dried, and then coated with vacuum grease before assembly.

2. Inspection and maintenance
Vacuum system inspection:
Check the operation status of the vacuum pump and cooling water daily, and observe the changes in vacuum degree in the vacuum chamber.
Regularly check the operating status of the vacuum pump to ensure that the pump oil is clean, sufficient, and the pump body is leak free.
Regularly replace the vacuum pump oil to avoid pump oil contamination affecting the vacuum degree.
Check the connection of the vacuum pipeline to ensure there are no leaks or blockages.
Heating system inspection:
Check the temperature control of the heating system daily for accuracy.
Regularly check the working status of the heating element to ensure that there are no open circuits or short circuits.
Regularly check the electrical connections of the heating system to ensure safety and reliability.
Water cooling system inspection:
Check the flow and temperature of the cooling water daily to ensure effective cooling.
Clean the pipes and radiators of the water cooling system to avoid blockage and scaling.
Regularly check the sealing of the water cooling system to prevent leaks.
Mechanical component inspection:
Check the operation of mechanical components daily, such as transmission mechanisms, sealing devices, etc.
Regularly check the lubrication condition of the transmission mechanism and add lubricating oil in a timely manner.
Check the sealing performance of the sealing device to ensure no leakage.
Regularly check the fastening of mechanical components to prevent looseness.

3. Operation precautions
Temperature control:
When the furnace temperature is above 400 degrees, the furnace door should not be opened for a long time to avoid affecting the temperature and vacuum inside the furnace.
The operating temperature should not exceed the maximum rated temperature of the furnace to prevent equipment damage.
Material Management:
Do not bring workpieces containing corrosive substances and moisture into the furnace for heating to avoid damage to the equipment.
Safe operation:
Maintenance operations should be carried out without power supply. If maintenance is carried out under live conditions, it must be carried out by professional maintenance personnel and ensure absolute personal and equipment safety.

4. Regular maintenance and overhaul
Weekly maintenance:
Clean the dust and impurities inside the vacuum chamber and on the surface of the heating element.
Check the position and contact condition of the thermocouple.
Check the fastening of mechanical components and tighten them promptly if they are loose.
Monthly maintenance:
Conduct a comprehensive inspection of the vacuum system, including vacuum pumps, vacuum pipelines, etc.
Check the working status of the heating element and replace it promptly if it is damaged.
Conduct a comprehensive inspection and maintenance of mechanical components.
Annual maintenance:
Thoroughly clean and maintain the vacuum sintering furnace, including the vacuum chamber, heating system, water cooling system, etc.
Conduct a comprehensive inspection and maintenance of the electrical system to ensure safety and reliability.
Replace vulnerable parts and consumables, such as thermocouples, sealing devices, etc.

By following the above daily maintenance recommendations, the stable operation and extended service life of the vacuum ceramic sintering furnace can be ensured. At the same time, it can also improve the stability of the sintering process and product quality.
