I. Lubrication System Maintenance
Poor lubrication is the main reason for excessive bearing temperature rise (accounting for 40%-80% of bearing failures). Maintenance should be performed in stages:
Daily inspection: Before each startup, check the oil level, pipeline leaks, and oil pump operation sound to ensure continuous oil film at lubrication points.
Regular maintenance: Replace the lubricating oil every 1-3 months or 500-1000 operating hours, clean the filter screen/filter element, and calibrate the oil supply pressure (oil temperature should not exceed 60℃).
Annual overhaul: Disassemble and inspect the oil pump annually, replace seals, and clean internal sludge from the system.
II. Key Component Management
Bearing maintenance:
Use lubricants containing anti-wear additives to prevent lubricant loss or contamination.
Check for bearing misalignment to avoid frictional heat generation due to bent shafts or loose fits.
Saw blade and transmission system:
Regularly sharpen or replace the saw blade to keep the teeth sharp and reduce extra heat generated by dullness.
Check the lubrication status of transmission components such as pulleys and lead screws to avoid dry friction.
III. Environment and Operation Optimization
Environmental control: The equipment should be stored in a well-ventilated, dry, and dust-free environment (temperature ≥-15℃, humidity ≤85%). In high-dust environments, the maintenance cycle should be shortened by 50%.
Heat dissipation design:
Optimize the layout of heat dissipation fins (e.g., using serrated fins to increase the heat dissipation area by 20%-30%).
Ensure that high-heat-generating components (such as motors) are tightly attached to the heat dissipation surface, and use high-thermal conductivity silicone pads (thermal conductivity ≥3W/(m·K)) to reduce thermal resistance.
IV. Regular Inspection and Recording
Weekly inspection: Tighten easily loosened components such as the hydraulic system and pulleys.
Monthly comprehensive maintenance: Including lubrication system cleaning, performance testing, and temperature monitoring.
