The repair technology of crusher bearing wear

Crusher bearing wear of 2019 - repair process 11 - 29 ( Luanchuan county new machinery and equipment repair center) Crusher shaft through the bearing support, was part of the heaviest load, it is easy to wear and tear parts. Below to introduce a way of crusher bearing savings, rapid repair. 1 new crusher prosthesis after wear of crusher bearing crusher bearing wear should be how to repair? Concrete repair methods: 1, the surface treatment: to repair welding need to processing artifacts, degreasing process, sandblasting derusting. Degreasing, moisture treatment: remove grease on the surface of the workpiece, in cotton wipe the surface, no oily be soiled, water be soiled cotton yarn. With oxygen acetylene flame adjustment to 10 cm long, at a speed of 5 cm/min, make fire repeatedly even baking surface, remove grease and moisture on the surface of the workpiece. Sandblasting derusting: remove the oxide layer on the surface of the workpiece, visual inspection, sandblasting surface visible metal grey uniform. After sandblasting processing artifacts that don't allow direct contact with grease gloves sandblasting surface, after sandblasting processing artifacts should pay attention to moistureproof. 2, production, mold, tool preparation, the workpiece preheating, XK series adhesive for preheating, in strict accordance with the ratio of adhesive mixed stirring, mixing after the completion of the adhesive is filled in on the sizing on plate to preheat the finished workpiece, after mixing adhesive in dish in residence time can't more than 3 minutes, to ensure the full of adhesive for bonding. After completion of construction, to detect defects repair in a timely manner. 3, curing conditions: in room temperature 30 & deg; 24 hours under natural curing, different conditions can prolong the curing time. 4, grinding, heat cured grinding workpiece in strict accordance with the size of the workpiece processing, sealing surface examination suitably qualified. 5, spray paint, after inspection, the workpiece to spray paint, spray paint surface evenly, there is no flow phenomenon. Note: XK series adhesive is a new mechanical repair center and the relevant scientific research units to develop a high-end repair wear-resistant material, has extensive should be used in mineral processing industry, metallurgical industry, power industry, chemical industry, etc.
