Various problems often occur during the use of the printing press, and the machine parts are often damaged and electrical failures occur frequently. Some people say that the machine is too old. The old machine is an objective reason, but the new machine does not fail? Some printing plants have more new machine failures than old ones. Objectively speaking, the use and failure rate of the machine include the following factors: the manufacturing quality of the machine, installation and commissioning, maintenance, reasonable operation, and the most important thing is the quality of maintenance. The quality of the machine exists objectively at the factory. Whether it is a new machine or an old machine, installation and commissioning are the first pass.
General new machines are installed and debugged when they leave the factory. After quality inspection, they are shipped separately. Not only the problem of level and reasonable installation, but also a problem of inspection and correction. The old machine should be more like this. As for maintenance and use, I won't say much, just want to talk about the quality of maintenance:
Maintenance is not simply disassembly, not only to find the cause of the failure, but also to find other problems that accompany it.
The printing press has a strict timing relationship, as well as assembly tolerances and adjustment values. Busy disassembly and excessive adjustment are the main reasons for the accelerated wear and recurrence of the machine.
The procurement and processing quality of spare parts does not necessarily require the use of original spare parts for any parts and electrical components. Original spare parts cost high and the procurement cycle is long. Unless special or critical spare parts, most other parts and electrical components can be substituted. , As long as you understand the parts processing technology and component characteristics.
In addition to the natural damage to the machine, circuit failure is mainly due to hidden failures that are not carefully derived from disassembly and installation, or failure to find machines and human factors that cause circuit failures.
