2, after-the-fact maintenance-BM (fault maintenance) This is the earliest maintenance method, that is, if there is a problem, it will be repaired, and if there is a problem, it will not be repaired.
3. Preventive maintenance-PM (preventive maintenance) This is based on inspection and maintenance, which uses condition monitoring and fault diagnosis technology to predict equipment, and eliminates potential faults in a targeted manner, thus avoiding and reducing downtime losses. It is divided into two ways: regular maintenance and predictive maintenance.
4. Improved maintenance-CM (Corrective maintenance) Improved maintenance is to constantly use advanced process methods and technologies to correct some defects and congenital deficiencies of equipment, improve the advanced nature, reliability and maintainability of equipment, and improve the utilization rate of equipment.
5. Maintenance prevention-MP (maintenance prevention) maintenance prevention is actually maintainability design, and it is advocated to seriously consider the reliability and maintainability of equipment at the design stage. Improve the quality of equipment from design and production, fundamentally prevent failures and accidents, and reduce and avoid maintenance.
6. Production Maintenance-PM (Productive Maintenance) is a maintenance system that takes production as the center and serves production. Contains the specific contents of the above four maintenance methods. The unimportant equipment is still maintained afterwards, and the important equipment is maintained preventively. At the same time, improve and maintain the equipment during maintenance, and pay attention to equipment maintenance (maintenance prevention) when selecting equipment or developing equipment by yourself.
