With the advancement of high-tech, complex structures, and automation of modern machinery manufacturing technologies, the requirements for maintenance have become more stringent and more difficult, and the status of maintenance has become increasingly important. This article briefly describes several typical representative maintenance methods: 1 Preventive maintenance methods with regular maintenance as the main form; 2 Reliability-centered maintenance methods; 3 Maintenance methods combined with regular and visual conditions; 4 Maintenance methods for future investment; 5 Green maintenance methods proposed in recent years for communication. 
1. Reliability-centered maintenance law and condition-based maintenance Reliability-centered maintenance is the core of modern maintenance theory. The point of view of system engineering is that the development, design, manufacture, and use of maintenance objects are all related to maintenance, and all links are centered around the reliability center. Therefore, the reliability of maintenance objects is constantly improved in the cycle. And improve.
The reliability-centered maintenance method is also the inheritance and development of traditional prevention-based maintenance methods. People's understanding of maintenance evolves from the original work-wear-failure-endangering safety to active and effective measures to control machinery. The reliability of the equipment is reduced to maintain the inherent reliability of the mechanical equipment.
Through the analysis of reliability factors in all aspects of mechanical equipment, scientifically determine maintenance work items, optimize maintenance methods, determine a reasonable maintenance period, and only do necessary maintenance work, even if the reliability of mechanical equipment is restored, Save on maintenance time and costs.
2. Maintenance-oriented and regular maintenance systems based on prevention
It has long been considered that the safety of machinery and 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 machinery and equipment is. This is the preventive maintenance method that we have used for many years. . That is, regardless of the technical condition and the use environment of each specific maintenance object, compulsory maintenance (such as the current requirements of the first, second, and third level maintenance) and targeted maintenance must be performed in accordance with the unified time or mileage. This method of regular maintenance is appropriate for the maintenance of early mechanical equipment and parts, and has played an important role in the maintenance of machinery and equipment in China.
The early regular maintenance system increased the maintenance workload, maintenance costs, and downtime. As a result, a lot of invalid maintenance was done, but random failures and early failures could not be eliminated in time. The statistical analysis of the fault data shows that regular maintenance does not work for the control of many faults. The decomposition inspection carried out cannot provide real-life conditions for when the parts that can be used may be faulty. Too many repairs are easy to do. Man-made failures, increased maintenance costs, and reduced maintenance efficiency. 
Theory has proved that for complex mechanical equipment, its failure is mainly random, and regular maintenance cannot eliminate random failures. Therefore, in the early 1960s, people began to question the traditional maintenance methods. During this period, some countries began to explore experimental work through the application of reliability syllabi, targeted maintenance, on-demand inspection and replacement, and on the basis of statistics, a reliability-centered maintenance method was initially developed.
