How should the tube furnace be maintained when not in use?
When the tube furnace is not in use, here are some maintenance methods:
1. Cleaning
- Thoroughly clean the inside of the furnace to remove residual samples, dust and debris.
- Wipe the outside of the furnace with a clean damp cloth to keep the appearance clean.
2. Check the components
- Check whether the heating elements are damaged, deformed or aged.
- Check whether the thermocouple connection is good and whether it is broken.
- Check whether the furnace tube is cracked, broken or corroded.
3. Moisture-proof treatment
- Place desiccant in the environment where the tube furnace is stored to prevent humid air from corroding the equipment.
- The furnace can be wrapped with plastic film or dust cover to reduce moisture intrusion.
4. Lubrication
- Apply a proper amount of lubricating oil to the moving parts of the tube furnace, such as the hinges of the furnace door, to maintain its flexibility.
5. Power on regularly
- Power on the tube furnace for a period of time at regular intervals (for example, every one or two months) to keep the internal electronic components in good condition and to drive away moisture.
6. Storage environment
- Choose a dry, well-ventilated and temperature-stable place to store the tube furnace, avoiding direct sunlight and heavy objects.
7. Sealing protection
- Ensure that the furnace door, air inlet and outlet are well sealed to prevent dust and foreign objects from entering.
8. Record maintenance information
- Record each maintenance operation, including the inspection situation, measures taken and maintenance time, so as to track the condition of the equipment and provide reference for subsequent maintenance.
The above maintenance measures can keep the tube furnace in good condition when it is not in use, extend its service life, and ensure normal operation when it is used again.
