Centrifuges are essential devices used to separate liquid and solid particles or different liquid components through the application of centrifugal force. Based on practical experiences from both domestic and international sources, here is a comprehensive guide on centrifuge maintenance and operational procedures.
**Centrifuge Maintenance and Operation:**
1. Before starting the centrifuge, always turn off the power supply and loosen the brake mechanism. Manually rotate the drum to check for any jamming or resistance.
2. Inspect all parts of the centrifuge for signs of looseness, damage, or unusual behavior.
3. Once everything looks good, turn on the power and start the drive in a clockwise direction. It usually takes about 40–60 seconds for the machine to reach normal operating speed from a stationary state.
4. After installation, it's recommended to run the equipment empty for approximately 3 hours to ensure there are no issues before loading any material.
5. Ensure that the material is evenly distributed inside the centrifuge to maintain balance and prevent unnecessary wear.
6. Always operate the centrifuge under supervision, and never exceed its rated capacity.
7. Avoid improper operation to extend the lifespan of the equipment and ensure safe usage.
8. If any abnormal noise, vibration, or performance issue occurs during operation, stop the machine immediately and perform an inspection or repair as needed.
9. Never touch the rotating drum while the centrifuge is running at high speed, as this can lead to serious accidents.
**Regular Maintenance Tips:**
To ensure long-term performance and reliability, it is advised to rotate the moving parts every six months. Check the lubrication condition of the bearings and look for signs of wear. Also, inspect the braking system components and replace them if severely worn. Make sure the bearing cover is free from oil leakage.
After each use, clean the centrifuge thoroughly and keep it in a clean and dry environment. Avoid using non-corrosion-resistant models when handling highly corrosive materials. Additionally, do not use non-explosion-proof centrifuges in flammable or explosive environments.
The mesh size of the filter cloth should be selected based on the particle size of the solid phase in the material being processed. An incorrect mesh size can affect the separation efficiency. When installing the filter cloth, make sure the sealing ring is properly placed into the drum’s groove to prevent material leakage.
