Printing presses often have various problems during use, such as mechanical damage and frequent electrical failures. Some people say that the machine is too old. Although the old machine is an objective reason, does the new machine not fail? In some printing factories, new machines have more failures than old machines. Objectively speaking, the usage and failure rate of the machine include the following factors: the manufacturing quality of the machine, installation and commissioning, maintenance, reasonable operation, and most importantly, the quality of maintenance. The quality of the machine objectively exists when it leaves the factory. Whether it is a new machine or an old machine, installation and debugging are the first hurdles.
Generally, new machines are installed and debugged when they leave the factory, after quality inspection, and then transported in separate packaging. It is not only a problem of level and reasonable installation, but also a problem of inspection and calibration. This is especially true for old machines. As for maintenance and use, I won’t say much. I just want to talk about the quality of maintenance:
Maintenance is not a simple disassembly and assembly, not only to find the cause of the failure, but also to find other problems that accompany it.
The printing press has a strict time coordination 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 parts and accessories does not necessarily require the use of original parts for all parts and electrical components. The cost of original parts is high and the procurement cycle is long. Unless special or critical parts, most of the 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 of the machine, the circuit fault is mainly the hidden fault derived from the careless disassembly and installation or the failure to find the machine and human factors that caused the circuit fault.
