Summary of Filling Machine Maintenance Knowledge

For enterprises that operate filling machines on a daily basis, improper routine maintenance will reduce the working efficiency and service life of the equipment, increasing production costs. Therefore, proper maintenance of filling machines is extremely important. To keep your filling machine operating in optimal condition every day, please refer to the maintenance tips summarized by experienced filling machine engineers:

1. Daily Maintenance

• Inspect the machine frequently during operation. Tighten loose components promptly if found.
• Check electrical circuits daily to ensure good contact and detect broken wires.
• Add lubricating oil as required to keep the machine running smoothly and reduce wear.
• Keep the equipment clean, especially the parts in direct contact with materials to meet sanitary requirements.
• For long-term shutdown: thoroughly clean residual materials to avoid corrosion. Apply anti-rust oil after cleaning and cover the machine with a dustproof tarpaulin.

2. Summer Maintenance Tips

• If the equipment is not used frequently, seal it after each run to prevent impurities from entering before next use.
• If abnormal noise occurs during operation, stop the machine and cut off power for inspection. The noise may be caused by insufficient gear lubrication or gear misalignment, which needs timely maintenance.
• Additional summer reminders: Check heat dissipation of motors and electric control boxes under high temperature to avoid damage to electrical components. Inspect sealing gaskets regularly, as high temperature accelerates gasket aging and liquid leakage.

3. Periodic Maintenance

• Weekly maintenance: Disassemble and clean filling valves and nozzles. Check gaskets for deformation, aging or leakage; tighten all transmission fasteners.
• Monthly maintenance: Replace lubricating grease; inspect wear of pumps, rotors and cylinders; calibrate filling accuracy; remove dust inside electric control cabinets.
• Annual overhaul: Fully disassemble the machine to inspect worn parts and replace aged components in batches; test motor performance and pressure pipelines; recalibrate the whole machine and apply anti-rust treatment.

4. General Precautions

• Always power off the machine before cleaning, lubrication or inspection. Never maintain the equipment when energized.
• For different materials (corrosive liquids, sauces, alcohol, etc.), select cleaning agents compatible with equipment materials (316L stainless steel, rubber seals) to prevent corrosion.
• Keep spare wearing parts such as gaskets, oil seals and filling nozzles in stock to cut downtime.
