Daily maintenance of vacuum sintering furnace

The daily maintenance of vacuum 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 sintering furnaces:

1. Cleaning and maintenance
Furnace body cleaning: Regularly clean the surface of the furnace body, remove dust and oil stains, and keep the furnace body clean and tidy.
Internal cleaning: Regularly clean the dust and impurities inside the vacuum chamber and on the surface of the heating element to prevent residue from affecting the sintering effect and vacuum degree.
Cleaning of sealing structure: When disassembling and assembling the sealing structure, it should be cleaned with alcohol or gasoline, dried, and then coated with vacuum grease before assembly to ensure sealing performance.

2. Inspection and maintenance
Power supply, gas source, water source inspection: Check the power supply, gas source, water source, etc. of the vacuum sintering furnace daily to ensure that the equipment can operate normally.
Vacuum pump inspection: Regularly check the operating status of the vacuum pump, including whether the pump oil is clean and sufficient, and whether there are any leaks in the pump body. At the same time, regularly replace the vacuum pump oil to avoid pump oil pollution affecting the vacuum degree.
Heating system inspection: Regularly check the working status of the heating elements to ensure that there are no open circuits or short circuits. At the same time, clean the dust and impurities on the surface of the heating element to improve heating efficiency.
Water cooling system inspection: Regularly check the flow and temperature of the cooling water to ensure cooling effectiveness. At the same time, clean the pipes and radiators of the water cooling system to avoid blockage and scaling.
Mechanical component inspection: Regularly check the lubrication condition of the transmission mechanism and add lubricating oil in a timely manner. At the same time, check the sealing performance of the sealing device to ensure no leakage. In addition, it is necessary to regularly check the fastening of mechanical components to prevent loosening.

3. Operation precautions
Temperature control: The operating temperature should not exceed the maximum rated temperature of the furnace to prevent equipment from overheating and damage. At the same time, regularly check whether the temperature control of the heating system is accurate.
Furnace door operation: When the furnace temperature is above 400 degrees, the furnace door should not be opened for a long time to prevent heat loss and pressure fluctuations inside the furnace.
Workpiece handling: Workpieces with corrosive substances and moisture must not be brought into the furnace for heating to prevent adverse effects on equipment and sintering efficiency.

4. Regular maintenance and overhaul
Weekly maintenance: Clean the dust and impurities inside the vacuum chamber and on the surface of the heating element every week, check the position and contact of the thermocouple, and the fastening of mechanical components.
Monthly maintenance: Conduct a comprehensive inspection of the vacuum system, including vacuum pumps, vacuum pipelines, etc. At the same time, check the working status of the heating element and replace it promptly if it is damaged.
Annual maintenance: Conduct comprehensive cleaning and maintenance of the vacuum sintering furnace, including the vacuum chamber, heating system, water cooling system, etc. At the same time, conduct a comprehensive inspection and maintenance of the electrical system to ensure safety and reliability. In addition, vulnerable parts and consumables such as thermocouples and sealing devices need to be replaced.

In summary, the daily maintenance of vacuum sintering furnaces involves multiple aspects, including cleaning and maintenance, inspection and maintenance, operational precautions, and regular maintenance and repair. Only by doing these maintenance work well can the long-term stable operation and extended service life of the vacuum sintering furnace be ensured.
