The failure of the machine is mainly due to the inability of certain parts in the machine to provide specific functions, causing problems in the operation of the equipment.During the service cycle of the equipment, the longer the equipment is used, the more likely it is to wear and tear, and the equipment will be overloaded multiple times during long-term operation.The most common causes of mechanical and electrical equipment failure include: (1) Wear and tear of parts.The degree of wear of parts is proportional to the time of electromechanical operation. The longer the running time, the greater the degree of wear.When the equipment is running to a certain point in time, the parts will age, and the parts will no longer be able to support their own functions, which will eventually cause mechanical and electrical equipment failure.(2) Failure and maintenance.Failure or failure to follow appropriate procedures will cause the greatest damage to the equipment. For example, sudden shutdown of the equipment may cause voltage or current mutations, which will cause damage to some fragile components; unreasonable maintenance will further damage the equipment, including untimely maintenance, insufficient maintenance and inappropriate maintenance methods.(3) Overload operation.Some enterprises use mechanical and electrical equipment for too long due to efficiency or other reasons, and overloaded work reduces the service life and increases the incidence of equipment failures during the service cycle .
