Daily maintenance of vacuum graphite furnace

The daily maintenance of vacuum graphite furnace is a key link to ensure its stable operation and extend its service life. Here are some specific maintenance measures:

1. Regular cleaning
Furnace body cleaning: Regularly clean the dust, oil stains, and other impurities inside and outside the furnace body to maintain the cleanliness of the equipment. This helps improve the heat dissipation performance of the device and maintain its good working condition.
Electrode and sensor cleaning: Regularly clean components such as electrodes and sensors to ensure their surfaces are clean and free of dirt, thereby ensuring the accuracy of signals and stable operation of equipment.

2. Inspection and fastening
Component inspection: Regularly inspect the fasteners, connectors, etc. of the equipment for looseness or detachment, especially graphite parts such as graphite crucibles, graphite trays, etc., and check for cracks or damage.
Tightening operation: When loose or detached parts are found, timely tightening operation should be carried out to ensure the stable operation of the equipment.

3. Lubrication and maintenance of transmission components
Lubrication of transmission components: For the transmission components of equipment, such as bearings, gears, etc., lubricating oil or grease should be added regularly to reduce wear and friction and ensure the normal operation of the equipment.
Check the lubrication system: Regularly check the oil level and quality of the lubrication system to ensure that the oil level is normal and the oil quality is good. If the oil quality is poor, it should be replaced with new lubricating oil in a timely manner.

4. Electrical system inspection
Check electrical circuits: Regularly check whether the circuits, connectors, components, etc. of the electrical system are intact, and promptly deal with any problems found.
Testing electrical performance: Regularly test and inspect the electrical system to ensure its stability and safety.

5. Maintenance of graphite components
Regular cleaning of graphite components: Use acid, alkali cleaning or soak graphite heating tubes and other components in clean water to remove surface dirt and sediment. When dismantling the furnace, the oxide in the thermal field should be cleaned, and the silicon infiltration on the graphite parts should be cleaned to ensure the cleanliness of the surface of the graphite parts.
Check the condition of graphite components: Regularly inspect the surface of graphite components for flatness, traces, cracks, or electrical leakage. If cracks or damage are found, they should be reported immediately and replaced.
Replace graphite parts: Based on the service life and actual situation of graphite parts, timely replace graphite parts that have reached the service life or have decreased performance. When replacing, graphite parts of the same model and specifications as the original pipe body should be selected.

6. Storage and Preservation
Avoid adverse factors: When storing and preserving graphite components, direct sunlight, moisture, and other adverse factors should be avoided to avoid affecting their performance and service life.
Avoid contact with chemicals: Avoid contact between graphite parts and chemicals such as acids and bases to prevent chemical corrosion.

7. Record and Review
Establish maintenance records: Detailed records of the time, content, personnel, and other information of each maintenance are kept for subsequent management and auditing.
Establish a review mechanism: Establish an inspection and review mechanism for graphite components, such as having a dedicated person responsible for inspection and review before several furnaces reach the expected service life, and then having higher-level management personnel responsible.

In summary, the daily maintenance of vacuum graphite furnaces involves multiple aspects, including regular cleaning, inspection and fastening, lubrication and maintenance of transmission components, electrical system inspection, graphite component maintenance, storage and preservation, as well as recording and review. By following these maintenance measures, the performance stability of the vacuum graphite furnace can be ensured, its service life can be extended, and equipment failures and maintenance costs can be reduced.
