It is from the standpoint of preventive "medical", according to the equipment frequent inspection records or operation with the quality of the main product, the production efficiency of the existence of signs of abnormality, before the equipment failure to carry out preventive repair and improvement. Preventive maintenance is usually scheduled according to the actual operation of the equipment.
2, breakdown maintenance: equipment failure or performance degradation of unplanned maintenance, also known as maintenance.
3, production maintenance: from the economic efficiency to improve the productivity of equipment maintenance methods, it is treated according to the degree of impact of equipment on production. Unimportant equipment using after-the-fact maintenance, the key key equipment for preventive maintenance.
4, predictive maintenance: according to the state of monitoring and diagnostic techniques to provide information, before the failure to carry out necessary and appropriate maintenance, also known as condition monitoring maintenance.
