Agricultural machinery parts commonly used repair methods

First, adjust the transposition method to replace the worn parts of a position, the use of parts not worn or lightly worn parts continue to work. Second, the repair size Note The damaged parts will be refurbished to change the geometry of the size, and at the same time with the corresponding changes in the accessories, in order to achieve the required technical parameters. If the cylinder of the Dongfanghong-75(54) tractor is worn out, the honing diameter can be increased by 0.25, 0.5, O.75, 1.0 or 1.25 millimeters in accordance with the repair size, and a correspondingly enlarged piston and piston ring can be used. Third, the additional parts method is assembled with a special part to the worn part of the part to compensate the wear of the part and restore its original matching relationship. Fourth, the replacement of parts and partial replacement method When the parts are damaged to repair or repair costs are too high; use new parts replacement; if parts of the parts are partially damaged, the damaged part can be removed to re-create a new part, with Welding or other methods connect the new replacement part with the base part of the original part to restore the working ability of the part. Fifth, restore the size of the method of welding (welding, gas welding, brazing), electroplating, spraying, plastic repair, forging, pressing, car, pliers, heat treatment and other methods, will restore the damaged parts to the technical requirements of the external dimensions and performance. In this method, economic benefits are taken into consideration, and the cost of a general repair part is about 5-50% of the original price. Infant child matters can not destroy the precision of the parts; can not reduce the surface hardness and wear resistance; can not change the metal matrix of the parts and produce a harmful residual force, can not affect the parts after the repair process.
