In this, we will discuss the maintenance procedures you require, wear parts, and safety best practices so that you can make the most of your HR two stage Pusher Centrifuge.
Routine Maintenance Checklist
Maintenance is what ensures smooth operation and functionality of your HR two stage Pusher Centrifuge. Note the following checklist:
Daily Maintenance
Inspect for Abnormal Vibration and Noise – Strange vibration or noise can be an indication of misalignment or bowl imbalance.
Inspect Oil Levels – The oil’s lubrication system needs the proper oil to avoid wear and overheating.
Check Feed Consistency – Verify that material fed contains the optimum particle size (>0.08mm) and concentration (>40%).
Clean Machine Surface – Dust or material residue accumulated on the machine surface must be cleared to avoid contamination.
Check Filter Cloth – Filter cloth should be cleaned and ensure it is free from obstruction since it will directly affect separation efficiency.
Weekly Maintenance
Inspect Bolts and Fasteners – All nuts and bolts have to be tightened in order to avoid mechanical breakdown.
Lubricate Bearings and Seals – Use the prescribed lubricant to lubricate bearings, seals, and moving parts for best operation.
Check Pusher Mechanism – Check piston pusher mechanism for excessive wear.
Check Electrical Parts – Check sensors, motors, and electrical contacts for efficient operating conditions.
Monthly Maintenance
Inspect the Bowl and Screen – The separation performance depends on the condition of the bowl and screen. Clean or replace if needed.
Analyze Oil Quality – If the lubrication oil appears contaminated, drain and replace it with fresh oil.
Test Emergency Stop System – Ensure the emergency shutdown system functions correctly for operator safety.
Measure Pusher Stroke – The pusher stroke should be within the specified 30-80 times per minute range for optimal performance.
Annual Maintenance
Complete Overhaul Inspection – Conduct a thorough check of all major components, including the main motor, auxiliary motor, and drive system.
Replace Worn-out Parts – Based on wear analysis, replace critical parts like bearings, seals, and gaskets.
Check for Corrosion – Inspect metal parts for signs of corrosion, especially if processing corrosive materials.
Calibration and Alignment – Ensure the bowl, pusher mechanism, and feed system are properly aligned to prevent uneven wear.
Common Wear Parts and Replacement Schedules
Certain components in the HR Two Stage Pusher Centrifuge experience more wear due to continuous operation. Regular replacement of these parts is essential for avoiding downtime.
| Wear Part | Expected Lifespan | Replacement Frequency |
| Filter Cloth | 3-6 months | As needed when clogged or damaged |
| Bearings | 12-24 months | Annually or based on vibration analysis |
| Seals and Gaskets | 12 months | Annually |
| Bowl Screen | 1-2 years | Replace if worn or clogged |
| Pusher Mechanism | 2-3 years | When movement efficiency declines |
| Lubrication Oil | 6 months | Every 6 months or based on condition |
We provide genuine spare parts that match the original specifications of your HR Two Stage Pusher Centrifuge, ensuring durability and reliable performance.
Training and Operator Safety Tips
Proper training and adherence to safety guidelines are crucial for both machine longevity and operator well-being.
Operator Training Best Practices
Understand Machine Functions – Operators should be familiar with all controls, including feed rate, separation factor, and pusher stroke settings.
Follow Startup and Shutdown Procedures – Always start and stop the centrifuge according to the manufacturer’s guidelines.
Monitor Performance Indicators – Keep track of vibration levels, noise, and material throughput to detect early signs of malfunction.
Use Correct Cleaning Methods – Avoid using aggressive chemicals that could damage machine parts.
Emergency Response Training – Operators should be trained in handling emergencies, including power failures, motor overloads, and material blockages.
Safety Precautions
Wear Protective Gear – Safety gloves, goggles, and hearing protection should always be worn when operating the centrifuge.
Ensure Proper Ventilation – Avoid exposure to harmful dust or chemical fumes during processing.
Lockout/Tagout Procedures – Before performing maintenance, disconnect power to prevent accidental startups.
Avoid Overloading – Feeding materials beyond the recommended capacity (e.g., 25-65t/h for the HR800 model) can lead to mechanical failures.
