The repair of automatic vacuum suction machines is different from the maintenance of conveying equipment. The main purpose of repair is to repair and replace worn or corroded parts, restore the technical and operational performance of the conveying equipment, and ensure its normal function. Repairs based on natural physical wear and tear are called normal repairs; The repair of sudden damage is called abnormal repair. Repair is an effective measure to restore the functionality of logistics equipment, a partial compensation for tangible wear and tear, and an important component of logistics equipment management. During the use of machinery, its components will gradually experience wear, deformation, fracture, corrosion, and other phenomena, known as visible wear.

Due to the different materials and operations of the components, varying degrees of tangible wear and tear may occur over a certain period of time, leading to a gradual deterioration of the mechanical technical condition, inability to operate normally, resulting in downtime, and even malfunctions, leading to mechanical accidents. Therefore, in order to maintain the normal operation of machinery, according to the changing laws of mechanical technology status, replace or repair worn and failed parts, and disassemble and adjust the whole machine or parts to restore mechanical efficiency, repair is carried out. So, repair is an important measure to maintain the normal technical condition of machinery for a certain period of time, and it is an important means for enterprises to maintain production.

The maintenance and repair of conveying equipment cannot be called upon each other, it is a relationship between "prevention" and "treatment". If the machinery is not repaired in a timely manner, its parts and components will experience accelerated wear or accidental damage, increasing the workload of maintenance. Do a good job in maintenance, timely eliminate hidden dangers, and prevent mechanical accidents before they occur, in order to prevent them before they happen. However, maintenance cannot eliminate the wear and tear of machinery. When the wear reaches a certain level, timely repair is necessary to restore the proper efficiency of the machinery. In addition, in the maintenance and repair of logistics equipment, safety operation technical measures should also be formulated to ensure personal and mechanical safety.
