Centrifuges play a vital role in industrial processes such as wastewater treatment, palm oil processing, food production, and chemical separation. However, like any piece of complex machinery, they are vulnerable to wear, improper use, and lack of maintenance. Identifying and addressing common problems early is essential to avoid costly downtime and extend the machine’s lifespan. Here are the top five centrifuge problems and practical solutions.

Excessive Vibration
This is one of the most common and damaging issues. It may result from misaligned installation, solids buildup, or worn bearings. Machines should always be installed on level ground. Regular cleaning, bearing inspection, and dynamic balancing of rotating parts can greatly reduce vibration.

Poor Separation Performance
If your centrifuge is producing wet cake or unclear filtrate, the problem may be improper feed flow, worn internal components (like the scroll or bowl), or incorrect differential speed. Operators should routinely monitor performance and adjust parameters accordingly. Replacing worn parts can restore optimal efficiency.

Motor or Gearbox Overheating
Overheating is often caused by insufficient lubrication, blocked airflow, or operating under excessive load. Always use the correct type and amount of lubricant. Keep ventilation areas clear and check oil temperature and pressure during operation.

Unusual Noises
Grinding, knocking, or screeching sounds often indicate serious issues like damaged bearings or the presence of foreign objects. When unusual noise is detected, the machine should be shut down immediately and inspected thoroughly.

Frequent Shutdowns or System Alarms
This may stem from sensor malfunctions, electrical faults, or imbalanced loads. Check for software errors in the PLC, calibrate sensors, and verify the feed distribution to avoid unnecessary shutdowns.

Conclusion

Preventive maintenance is the key to stable performance. Weekly inspections, timely part replacements, and proper training for operators can dramatically reduce failure rates.
