Issues that need to be checked in Chinese medicine extraction tanks.

When using a TCM extraction tank, the following precautions should be observed:

1. **Maintenance of Moving Parts**: Keep all moving parts, such as bearings, shafts, cylinder rods, pistons, and adjustment bolts, clean and properly lubricated.

2. **Sealing Maintenance**: Loosen the main tank feed and slag outlets when the equipment is not in use to prevent the sealing coils from losing elasticity. If air leaks occur, use the adjustment bolts and handle to reseal them, and replace the gaskets if leakage persists.

3. **Heat Retention**: Heat the main tank and scum trap to minimize heat loss.

4. **Gas Tank and Solenoid Valve Seals**: Replace the sealing rings if air leaks are detected at the gas tank or solenoid valve.
