A decanter centrifuge maintenance program should include daily, weekly, monthly and annual measures. Well-trained plant operators can be very proficient in operation. Some of the more critical centrifuge problems may require dedicated maintenance facilities or technicians.
HUADA have over 30 years of experience manufacturing, servicing and repairing decanter centrifuges, making us qualified to share the following centrifuge inspection and maintenance programs.
Operators should perform a daily centrifuge walk-through. The following are some of the basic components and functions that need to be checked.
Fasteners and guards: visually inspect for loose external bolts and cracked guards.
Discharge hopper and piping: check for leaks.
Noise and vibration: Observe noise and vibration levels on the panel.
For information on recommended weekly maintenance tasks, refer to your operation and maintenance manual, including the following.
Grease decanter centrifuge's inner bearings. You will need to manually lubricate the internal bearings of the centrifuge. Automatic lubrication systems cannot perform this operation.
Lubricating the internal bearings is important because it: supplies fresh lubricant, flushes out any contaminants and indicates the condition of the bearings.
Check the belt tension. If the belt has slackened, it needs to be replaced promptly.
The following are some recommended monthly maintenance items for centrifuges.
Check for wear: check rotor and housing for wear
Wiring, electrical components: Check for wear or damage
Discharge area: Check solid and liquid discharge areas for wear and blockage.
Perform function checks to verify operation of interlocking devices and system controls. Also, check PLC batteries. The main and internal bearings of the centrifuge should be replaced every 15,000 hours.
If needed, other centrifuge wear components, such as feed and discharge nozzles and tiles, should also be inspected and replaced.
