In the daily production of Mitsubishi series presses, the chain lubrication system is one of the most common issues encountered by press operators and maintenance personnel. These Japanese-built machines are known for their high durability and stable ink density, with cylinder diameters designed to balance speed and quality. If the problem is not addressed in time, it can at best affect registration accuracy and print quality, and at worst lead to extended downtime.
1. Fault Symptoms: Abnormal noise, tooth skipping, and elongation of the main drive chain; automatic lubrication alarms; excessively high oil temperature.
2. Cause Analysis: Blockage in the lubrication oil circuit; deterioration of oil quality; insufficient pressure from the automatic lubrication pump; improper chain tensioning; misalignment of the oil-mist lubrication nozzles. Given that Mitsubishi Japanese machines are renowned for high durability and stable ink density, with cylinder diameters designed to balance speed and quality, troubleshooting should prioritize checking key components and standard parameters.
3. Parts Replacement: Clean the oil circuit and replace with qualified lubricating oil; verify lubrication pump pressure and cycle; adjust chain tension; correct nozzle positions.
4. List of Wear-Prone Parts: For the chain lubrication system, it is recommended to keep in stock: relevant bearings/bushings, Mitsubishi-compatible sensors and suction nozzles, seals, and standard wear rollers. When replacing, always use genuine or certified parts and verify model numbers.
5. Preventive Measures: Change the oil at scheduled intervals; monitor oil temperature and pressure; perform regular tension inspections. The above methods also apply to models such as the D3000, DiaPress, Diamond series, and 3F. For actual operations, refer to the MAC automated control system / CCB ink fountain and on-site conditions. In complex situations, it is recommended to contact professional maintenance support through the printm.cn platform.
