Vertical mill rod head bearing a repair site operation

Vertical mill, widely used in cement, electric power, metallurgy, chemical industry, the gold is mine, etc, is a kind of ideal large grinding equipment, can be massive, granular and powdered materials into the requested powder material, it sets the crushing, boring, grinding, grading walks into an organic whole, consumption of high efficiency. Therefore, vertical mill parts repair, especially the shaft problems is one of the most focus on industrial problems of enterprises continuously. Rod mill bearing an once attack the wear and tear, the result not only only is delayed industrial consumption, so the repair technology is multifarious. Once lost market earlier traditional repair technology, with high-tech to invoke, online repair is more and more love. Such as sauvy carbon nano polymer technology, is a relatively perfect and mature repair process. （ 1) Sauvy industrial carbon nano polymer technology has the following the criterion in axial wear repair: (1) is mainly used in static coordinate the repair wear and tear, and carbon nano polymer materials meet the needs of field devices operating temperature, vibration, compression wear, cohesive force, and various kinds of size and other request; (2) sauvy industrial carbon nano polymer materials about axial repair first to ensure concentricity of the equipment request; (3) sauvy industrial carbon nano polymer materials about axial repair guarantee repair with the request, the repair process can reach cooperate with area of more than 95%, far higher than that of any a kind of traditional repair technology, including machining after the appearance of matching area; (4) after repair the appearance of interference fit, cone cooperation, bulging tight fit, key mating surface cohesion and so on parts assembly requirements; 5. Ensure to repair effect, such as rolling bearing with shaft or the bearing wear, just smooth normal bearing operating temperature in sauvy carbon nano polymer material request, within the scope of the bearing is not attack ablation or lock, component unit and tighten request to stop operation, strict according to sauvy process can reach a long-term use of requests, its use life beyond any kind of traditional repair technology, even beyond the using life of the new parts. （ 2) On-site repair situation: the scene view rod head wear, found that the wear is relatively serious, not only affects the matching surface, and wear incurred between components with concentric has also been affected. The detailed repair process is as follows: (1) appearance baking oil, polished, remove oil appearance and high; (2) application sauvy industrial special measuring tool wear size measurement of appearance, and depends on the size measurement of wear stop welding anchor point, with special measuring tool measuring and grinding out the height of the point, that is ready to work is to get a job; (3) empty try lhe swelling, quantity measurement of lhe swelling of preload, and accurately recorded data; (4) using anhydrous ethanol cleaning appearance; According to the proportion sauvy SD7104 carbon nano polymer materials, daub to axle appearance the harmonic good information. Lhe swelling of the exterior daub SD7000 tuomoji, bulging tight set device in place, the preload and the empty test of preloaded adhere to differences; (5) by using iodine tungsten lamp and expand from tight set of plane surface, accelerate the curing and progress data after curing performance; 6. Remove lhe swelling sets of data after curing, remove excess material, and clearing out the tank; 7) adjust the concave and convex seal clearance, after everything is ready in accordance with the joint bearing torque device and lhe swelling, repair at the end. Late in the process of operation in accordance with the request to stop a second and three fastening bulge tight set, in order to reach better use effect. 3.
