I. Common Lubrication System Faults
1. Abnormal Oil Pressure
Excessive Oil Pressure: Oil pipe blockage or oil pump failure leading to poor oil supply
Low Oil Pressure: Oil pipe leakage, air inflow to the oil pump, or insufficient oil supply
2. Bearing Overheating
Insufficient Lubrication or Oil Quality Deterioration (e.g., Metal Particles, Emulsification)
Oil Line Blockage Preventing Lubricant from Reaching Lubrication Points
3. Lubrication Failure
Incorrect Lubricant Type or Mixing Different Brands
Poor Seals Leading to Dust/Moisture Intrusion into the Lubrication System
4. Oil Leakage
Oil Leakage Due to Deteriorated Seals or Loose Bolts
Damaged Oil Tank or Loose Oil Pipe Joints
II. Troubleshooting
1. Abnormal Oil Pressure
Clean or replace blocked oil pipes and inspect Check the oil pump for leaks.
Adjust the oil pump pressure valve to ensure the oil supply meets the standard.
2. Bearing Overheat Treatment:
Replace the lubricant with a qualified lubricant (such as No. 3 molybdenum disulfide lithium grease) and clean the oil lines.
Check the cooling water system to ensure effective bearing cooling.
3. Lubrication Failure Treatment:
Use the lubricant specified in the equipment manual.
Inspect seals and clean lubrication lines regularly.
4. Oil Leak Treatment:
Replace sealing gaskets or tightening bolts, and repair the oil sump.
Use used belts to enhance nut sealing.
III. Preventive Measures:
Replace the lubricant every 2000 hours (reduced to 1500 hours in dusty environments).
Regularly check the oil level and quality to avoid mixing different types of grease.
Preheat the lubricant to above 20°C in winter to prevent freezing in the oil lines.
