How should general mechanical equipment be maintained?

People have long believed that the safety of mechanical equipment depends on its reliability. Therefore, it is believed that the more preventive work is done, the shorter the repair cycle is, and the more reliable the mechanical equipment is. This is the principle of regular maintenance that we have used for many years. Master's approach to preventive maintenance. That is, regardless of the technical status and usage environment of each specific maintenance object, mandatory maintenance (such as the current first, second, and third-level maintenance) and targeted maintenance must be carried out according to the uniformly prescribed time or mileage. This method of regular maintenance is more suitable for the maintenance of early mechanical equipment and parts, and it once played an important role in the maintenance of mechanical equipment in our country. ?

The early periodic maintenance system increased the maintenance workload, maintenance costs and downtime. As a result, a lot of ineffective maintenance was done, but random faults and early faults could not be eliminated in time. Statistical analysis of fault data shows that regular maintenance does not play a role in controlling many faults. The decomposition inspection carried out cannot provide the true situation of when the parts that can still be used may fail. Excessive dismantling and repairing will easily lead to failure. Human failures occur, maintenance consumption is increased, and maintenance efficiency is reduced. ?
