The daily maintenance and upkeep of vacuum sintering furnaces are key to ensuring their normal operation, extending their service life, and improving production efficiency. The following are detailed suggestions for daily maintenance and upkeep of vacuum sintering furnaces:

1. Daily inspection

Inspection of power, gas, and water sources:

Check the power supply, gas source, and water source of the vacuum sintering furnace daily to ensure stable power supply and that the air and water pressure meet the working requirements.

Vacuum system inspection:

Observe the changes in vacuum degree in the vacuum chamber to ensure that the vacuum pump and cooling water are in good operating condition.

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.

Check the connection of the vacuum pipeline to ensure there are no leaks or blockages.

Heating system inspection:

Check if the temperature control of the heating system is accurate and ensure that there are no open or short circuits in the heating elements.

Clean the dust and impurities on the surface of the heating element to improve heating efficiency.

Mechanical component inspection:

Check the operation of mechanical components such as transmission mechanisms and sealing devices to ensure good lubrication, no looseness, and no leakage.

Furnace cleaning:

Clean the furnace body, instruments, and control cabinets daily to keep them clean and free of debris.

Regularly clean the interior of the vacuum chamber to remove any residue and maintain its cleanliness.

2. Regular maintenance

Vacuum pump maintenance:

Regularly replace the vacuum pump oil to avoid pump oil contamination affecting the vacuum degree.

Clean the oil and impurities inside the vacuum pump, check the sealing of the pump, and ensure that there is no leakage in the pump body.

Heating element maintenance:

Regularly check the working status of heating elements, and replace them in a timely manner if aging, breakage, or other phenomena are found.

Water cooling system maintenance:

Regularly check the flow and temperature of the cooling water to ensure the cooling effect.

Clean the pipes and radiators of the water cooling system to avoid blockage and scaling.

Check the sealing of the water cooling system to prevent leakage.

Mechanical component maintenance:

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.

Electrical system maintenance:

Regularly check the connection status of the electrical system to ensure safety and reliability.

Check the working status of power lines, sensors, controllers, and other components to ensure their normal operation.

3. Other precautions

Safety operating procedures:

When operating and maintaining the vacuum sintering furnace, safety operating procedures should be strictly followed, protective equipment should be worn to ensure the safety of personnel and equipment.

Preventing pollution:

Do not bring workpieces containing corrosive substances and moisture into the furnace for heating, in order to avoid contaminating the furnace and damaging the equipment.

Keep the workplace dry to prevent moisture from entering the furnace.

Idle equipment handling:

For furnaces that have been idle for a long time, it is necessary to perform low-temperature operation under vacuum at least once every two weeks to check the working condition of the furnace.

When the vacuum sintering furnace is not in use, the furnace cover should be sealed and evacuated or filled with pure argon gas at a certain pressure (lower than atmospheric pressure) to protect the dry atmosphere inside the furnace chamber.

Regular renovation:

Regularly check the condition of the paint on the surface of the furnace shell. If there is any peeling or damage, it should be repaired and refurbished in a timely manner.

By implementing the above daily maintenance and upkeep measures, potential issues with the vacuum sintering furnace can be promptly identified and resolved, ensuring the normal operation and production efficiency of the equipment. At the same time, it can also extend the service life of the equipment and reduce maintenance costs.
