Farewell to watch roller press shaft repair process

Due to large roller press the volume and weight, dismantling, and transportation work and repair repair cycle become the most concern. Repair welding of ordinary machining process requirements of shaft overall demolition, after a heavy machinery and transport consumption manufacturers stop return equipment maintenance, so that overall demand cycle is about 20 days, or even longer. Comprehensive repair cost also is in 150000 yuan of above. So serious delayed the consumption of the enterprise, and the huge maintenance costs and production losses, enterprise is unbearable. Sauvy industrial carbon nano polymer materials for roller press bearing wear a online repair technology sauvy industrial carbon nano polymer materials repair technology is applied on the mechanical properties of the carbon nano polymer material characteristic and the corresponding repair process online repair roller press shaft wear and tear of large axle, etc. Repair process is simple: appearance disposal - Adjust the concentric - Apply data - Plant bearing - Adjust the preload and pre-tightening force. Its advantage is good cohesive force, good pressure resistance, abrasion resistance and have metal has comprehensive mechanical properties such as elastic deformation of the complete online repair, machine repair, repair of high efficiency and no demand of equipment a large number of disassembly, eight hours - ordinary situations Completed within 24 hours. Sauvy industrial carbon nano polymer material similar to a cold welding technology, on-line repairing process does not produce high temperature, good maintenance equipment from damage of ontology, and in the process of repair is not restricted by axial uneven wear amount. Polymer materials in the process of using carbon nanotubes will not produce metal fatigue wear and tear, in normal maintenance under the premise of care equipment, its use life and higher than that of the new parts after the restoration of life. Above all, sauvy industrial carbon nano polymer material has the repair repair crane main shaft wear of high efficiency and can be completed online repair, machine repair, comprehensive repair capital is low, to the enterprise equipment maintenance maintenance provide powerful processing plan, reduce the consumption of the enterprise capital. Roller press bearing wear online repair step 1. When the device operating temperature in - 20 - 100 ℃ range, initiative adopts sauvy SD7101H carbon nano polymer materials; 2. Remove the repair parts and other related parts, ensure sufficient construction space; 3. Check repair parts wear size dosage of certain data and the benchmark anchor point; 4. Roasted with acetylene flame out into the wear appearance of grease, until no sparks, grease carbide, baking process control metal temperature below 90 ℃, can be divided into baking frequently; （ To avoid deformation of parts and the bonding performance of progress data) 5. Power tools will stop wear parts appearance burnish disposal, the purpose is to remove impurities and oxide layer, ensure that the rough outside ( Do not grind the unworn datum) ； 6. With acetone or ethanol will stay clean clean, repair parts and the corresponding parts ensure appearance clean and dry; 7. Daub SD7000 tuomoji in the corresponding assembly parts appearance, to an average of both sides to ensure no dead Angle, natural drying or air drying; 8. Severe proportionally mixed sauvy SD7101H carbon nano polymer materials, high mixing to color differences on average, no color difference; 9. Repair parts tightly daub sauvy SD7101H carbon nano polymer materials, in order to not wear appearance as a benchmark research restore restore a size, to measure data after curing, ensure that size is higher than the original fit tolerance after the restoration of 0. 03 ~ 0. 05mm； 10. Application with parts stop changing outfits and grinding high, clearing redundant data; 11. With acetone or ethanol will stay again repair parts and the corresponding parts washing clean; 12. Again to reconcile a moderate amount of data, in the first time data on the warp and woof of apply a layer of thin, dry grounded in assembly parts release agent on also apply a layer of thin materials directly to stop parts after assembly; 13. Assembly in place after remove extrusion repair materials with scraper, it is best not to move parts before data curing; 14. To stop the curing time, data complete curing condition is: 24 hours / 24 ℃, the temperature of each ascending 11 ℃, the curing time shorten the half, but ascending temperature shall not exceed that of the data for temperature. （ Referred to in the above temperature for the data itself, not the environment temperature) According to the site temperature and curing time reference details technical data sheet. Can after iodine tungsten lamp or hot fan heating shorten curing time, pay attention to, not with open direct contact information, and heating temperature beyond material shall be the highest for temperature, don't let the data of temperature and substrate temperature difference is too big, rising and dropping drastically to prevent. Sauvy industrial field repair roller press bearing wear of case enterprise with a 150 - hefei court Type 100 rolling machine, roller pressure motorized roller driving side bearing wear, bearing a unilateral wear is 1. More than 5 mm, width 480 mm wear and tear, bearing type 232/600.
