How to Repair Agricultural Machinery Parts

There are three basic methods for the repair of agricultural machinery parts: the repair technology of restoring the size, the repair technology according to the repair size and the special repair technology. The repair technology of restoring size includes welding and surfacing, thermal spraying, electroplating, electroless plating, electric spark covering and melting and casting metal layer, etc; Repair technology according to repair size, including machining, fitter, additional parts method, local replacement method, transposition method, etc; Special repair technologies include correction of deformation, surface strengthening, sealing and plugging, bonding and patching, pressure processing, etc.

 At present, the repair technology commonly used in production should vigorously promote and adopt effective advanced repair technology under economic and reasonable conditions in accordance with the principle of "focusing on repair and supplemented by replacement". There are many repair methods for damaged mechanical parts. In addition to the basic methods of machining (such as turning, boring, planing, grinding, milling and other processes), there can also be a variety of process schemes, such as welding repair, repair, spraying, plating, riveting, inserting, matching, modification, correction, swelling, compression, bonding and so on. The rapid development of science and technology has promoted the improvement of repair technology. New science and technology has been widely used in the repair process of mechanical parts. However, in the repair of specific parts, we should analyze the structural characteristics, use requirements, working environment and other factors of the parts, and determine a more reasonable and economical repair process through technical and economic analysis according to the characteristics and scope of application of different repair methods.
