Scientific maintenance can extend equipment life and ensure processing quality. It should be divided into two categories: daily maintenance and periodic maintenance.
Daily Maintenance (Before and After Daily Operation):
Cleaning: Use compressed air to clean adhesive residue, dust, and other contaminants from the press plate surface. Wipe the machine body and electrical control cabinet to ensure proper heat dissipation. Check the area around the oil tank for debris to prevent oil buildup and potential safety hazards.
Inspection: Before starting, confirm that the hydraulic system is leak-free and the oil level is within the marked range. Test the emergency stop button, safety light curtain, and other protective devices for sensitivity and effectiveness. Observe for any abnormal noises during no-load operation and check if the pressure gauge pointer is stable.
Lubrication: Add lubricating oil (such as grease) to the rack, pinion, and other transmission parts of the balancing mechanism to ensure smooth lifting without jamming.
Periodic Maintenance (Monthly/Quarterly):
Hydraulic System: Check the cleanliness of the hydraulic fluid monthly. Replace it immediately if it becomes cloudy or emulsified. Clean the oil tank filter and hydraulic pump quarterly. Check the aging of seals and replace worn seals to prevent oil leaks.
Mechanical Components: Tighten bolts and nuts on the machine body, cylinders, motors, etc. monthly to prevent loosening; check the flatness of the pressure plate quarterly, and level it if deformation is found; check the meshing clearance of the balance gear and rack, and replace it promptly if excessively worn.
Electrical System: Check cables for damage quarterly, check contactor and relay contacts for oxidation, clean dust from the electrical box, and ensure reliable circuit connections.
