In daily production on Komori series presses, the air pump vacuum system is one of the most frequently encountered issues for press operators and maintenance personnel. These Japanese-built machines are known for their stability, with mature H-UV drying and automatic registration systems, and uniform ink train distribution. If the problem is not addressed promptly, it can at best affect registration accuracy and print quality, and at worst lead to extended downtime.
1. Fault symptoms: Insufficient feeder suction, weak delivery suction, unstable vacuum gauge readings, abnormal noise and overheating from the air pump.
2. Cause analysis: Vacuum pump vane wear, carbon dust accumulation, hose cracking and air leakage, clogged filters, oil-contaminated clogged silencers. Given that Komori Japanese presses are renowned for stability, with mature H-UV drying and automatic registration systems and uniform ink train distribution, troubleshooting should prioritize checking critical components and standard parameters.
3. Operational pitfalls: Replacing vacuum pump vanes and cleaning the chamber, leak-checking and replacing damaged hoses, cleaning or replacing filters, cleaning silencers.
4. Common mistakes: Never blindly increase pressure or water supply based on experience; any parameter changes on the Komori console must be recorded and verified; do not forcibly bar the press or bypass safety interlocks while the machine is running.
5. Preventive measures: Regularly change oil and filter elements, monitor for abnormal noise as an early warning, and keep the air path dry. The above methods also apply to models such as LS440, LS629, Lithrone, GL840, and G40. For actual 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.
