Repair process: 1, with oxygen - acetylene flame grilled scratched site (control temperature, avoid surface annealing), the perennial infiltration metal surface oil baked, grilled to no sparks. 2, will scratch the surface treatment area with angle grinder Xinjiang self-resetting hydraulic cylinder, sanding depth more than 1 mm, and a groove along the rail grinding Daqing landing hydraulic cylinders, preferably dovetail. Shaanxi rod ends drilled deeper scratches hydraulic cylinders, change the forces. When the wounds caused by the contact measuring instrument commonly used cylinder gauge measuring cylinder diameter, measuring the contact side friction side is inserted in the cylinder bore wall, measuring contacts are mostly made of cemented carbide wear Gao hardness.
