The third type of preventive maintenance. In order to ensure that the technical performance and accuracy of electromechanical equipment does not deviate, and at the same time reduce the probability of its failure, the inspection and maintenance of its maintenance plan and maintenance plan in accordance with the relevant regulations is called preventive maintenance. Preventive maintenance operations carried out during the specified period of time are called regular inspections and maintenance, and its notable feature is that it has a certain periodicity. The periodicity is determined by the failure period of the parts of the electromechanical equipment. The different failure cycles of mechanical and electrical equipment components result in different repair contents, repair cycles, and repair workloads. This maintenance method is suitable for the assembly line that is familiar with the wear rules of mechanical and electrical equipment parts or continuous production. Another maintenance method is based on the performance status of electromechanical equipment and preventive maintenance according to its needs. This maintenance method is called condition monitoring maintenance. Condition monitoring and maintenance are based on the technical diagnosis of auxiliary instruments and meters, so as to obtain the operating state performance indicators of the electromechanical equipment. According to the comparison of the detection indicators and the standard technical indicators, the maintenance work is arranged in a timely manner. Therefore, the basis of this maintenance method is the information provided by daily inspection, maintenance, operation, regular maintenance and instrumentation testing. The advantage of condition monitoring and maintenance is to be able to grasp the initiative of maintenance of electromechanical equipment, which can not only improve the actual rate of electromechanical equipment, but also extend the service life of electromechanical equipment. This maintenance method is suitable for key installations, key electromechanical equipment and high-precision electromechanical equipment. Condition monitoring and maintenance is a trend in the development of mechanical and electrical equipment maintenance in the future.
