In the daily production of Komori series printing presses, the chain lubrication system is one of the most frequently encountered issues for press operators and maintenance personnel. These Japanese-made machines are known for their stability, with mature H-UV drying and automatic registration systems, as well as even ink distribution across the ink train. If not addressed in a timely manner, the problem can range from affecting registration accuracy and print quality to causing extended downtime in severe cases.
I. Fault Symptoms: Abnormal noise from the main drive chain, chain skipping, chain elongation, automatic lubrication alarms, and excessively high oil temperature.
II. Cause Analysis: Clogged lubrication oil passages, deteriorated oil quality, insufficient pressure from the automatic lubrication pump, improper chain tensioning, and misaligned oil-mist lubrication nozzles. Given that Komori Japanese machines are known for their stability, with mature H-UV drying and automatic registration systems and even ink distribution, troubleshooting should prioritize checking key components and standard parameters.
III. Parts Replacement: Clean the oil passages, replace with qualified lubricating oil, verify lubrication pump pressure and cycle, adjust chain tension, and correct nozzle positions.
IV. List of Wear-Prone Parts: For the chain lubrication system, it is recommended to keep the following in stock: relevant bearings/bushings, Komori-compatible sensors and suction nozzles, seals, and standard wear rollers. When replacing, always use genuine or certified parts and verify model numbers.
V. Preventive Measures: Change oil at scheduled intervals, monitor oil temperature and pressure, and perform regular tension inspections. The above methods also apply to models such as LS440, LS629, Lithrone, GL840, and G40. For practical operations, refer to the PQC Print Quality Control System / KMS console and on-site conditions. For complex situations, it is recommended to contact professional maintenance support through the printm.cn platform.
