I. Core Measures for Lubrication Management
1. Oil Selection and Replacement
Strictly select lubricant brands (such as No. 3 molybdenum disulfide lithium grease) according to the equipment manual.
Replace lubricating oil every 2000 hours (reduced to 1500 hours in dusty environments).
Throughly clean the oil circuit during oil changes to avoid mixing new and old oil.
2. Lubrication System Maintenance
Regularly clear oil pipe blockages to ensure unobstructed oil flow.
Check the integrity of the oil sump and repair any damage to ensure proper oil flow.
II. Preventive Maintenance of Key Components
1. Bearings and Bushings
Control the amount of grease added to 1/3-1/2 of the bearing clearance.
Adjust the journal-bearing clearance to the standard value (usually 0.5-1.2 mm).
2. Sealing and Cooling
Reinforce bearing seals to prevent dust and Water intrusion
Check the cooling water system; increase the water supply in summer.
III. Operation Monitoring and Operating Specifications
1. Real-time Monitoring
Immediate alarm if the main bearing temperature exceeds 55°C; forced shutdown at 60°C
Check the oil level and quality daily (emulsification/metal particles require oil change)
2. Operating Specifications
Preheat the lubricating oil to above 20°C before starting in winter
Avoid idling (idling leads to poor lubrication)
IV. Systematic Maintenance Plan
1. Periodic Inspection
Monthly inspect the liner bolts and lubrication lines
Quarterly clean the lubrication system and replace the filter
2. Fault Warning Mechanism
Establish a lubrication system fault diagnosis file (record abnormal oil pressure and temperature)
Train operators to identify early signs of failure (such as unusual noise and vibration)
