Welcome to appreciate the roller press shaft repair process - bearing knowledge

Due to large roller press the volume and weight, dismantling, and transportation work and repair repair cycle become the most concern. General workpieces machining process need to remove for shaft as a whole, return through heavy machinery and transport equipment manufacturer for repair, so that the overall need cycle is about 20 days, or even longer. Comprehensive repair cost also is in 150000 yuan of above. So serious delayed the production of the enterprise, and the huge maintenance costs and production losses, enterprise is difficult to accept. Sauvy industrial carbon nano polymer materials for roller press bearing a wear online repair sauvy industrial carbon nano polymer repair technology is the use of carbon nanotubes unique mechanical properties of polymer materials and the corresponding repair process online repair roller press shaft wear and tear of large axle, etc. Repair process is simple: surface treatment - Adjust the concentric - Apply materials - Install the bearing - Adjust the preload and pre-tightening force. Its advantage is good cohesive force, good pressure resistance, abrasion resistance and have metal comprehensive mechanics performance of elastic deformation and so on to realize online repair, machine repair, repair efficiency is high, don't need a large number of disassembly, to equipment - usually eight hours 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 to protect equipment from damage of ontology, and in the process of repair is not restricted by axial uneven wear amount. Carbon nano polymer materials in use process does not produce metal fatigue wear and tear on the premise of normal equipment maintenance, the service life of repaired even higher than the service life of the new parts. To sum up, sauvy crane industrial carbon nano polymer materials to repair the spindle wear under repair with high efficiency, which can realize the online repair, machine repair, etc. , comprehensive repair cost is low, to the enterprise equipment maintenance maintenance provides a powerful solution, greatly reduce the production cost of enterprises. Roller press bearing wear online repair step 1. When the temperature of the equipment operation in - 20 - 100 ℃ range, recommended sauvy SD7101H carbon nano polymer materials; 2. Remove the repair parts and other related parts, ensure sufficient construction space; 3. Check to make sure repair parts wear size materials dosage and benchmark anchor point; 4. With acetylene flame grilled the grease of the infiltration of the wear surface, until no sparks, grease carbide, baking process control metal temperature below 90 ℃, can be divided into many baking; ( To prevent the deformation of parts and improve the bonding performance of the material) 5. With electric tool wear parts surface polishing treatment, the purpose is to remove impurities and oxide layer, ensure that the rough surface ( Do not grind the unworn datum) ; 6. With acetone or ethanol will stay clean, repair parts and the corresponding parts to ensure a clean, dry surface; 7. Corresponding assembly parts in the smear SD7000 release agent, to smear evenly on both sides to ensure that no dead Angle, natural drying or air drying; 8. Strictly proportional to reconcile sauvy SD7101H carbon nano polymer material, fully mixing to uniform color, no color difference; 9. Repair parts tightly daub sauvy SD7101H carbon nano polymer materials, based on worn surface not blow grind to restore the original size, after waiting for material curing measure size, ensure that size is higher than the original fit tolerance after the restoration of 0. 03 ~ 0. 05mm； 10. The use of matching parts for fitting and abrasive highs, clearing excess materials; 11. With acetone or ethanol will stay again repair parts and the corresponding parts clean; 12. Again to reconcile a moderate amount of material, on the basis of the first pass material apply a layer of thin, on the basis of dry assembly parts release agent also apply a layer of thin materials directly after the parts assembly; 13. Assembly in place after remove extrusion of restorative materials with scraper, before curing material had better not move components. 14. Adequate curing time, material completely 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 materials under temperature. ( Referred to in the above temperature for the material itself, not the environment temperature) Concrete curing time according to the temperature and the reference material technical data sheet. Can be by iodine tungsten lamp or hot fan heating shorten curing time, pay attention to, not with open flame, direct contact with the material and heating temperature shall not exceed the material the highest temperature, don't let the material temperature and substrate temperature difference is too big, rising and dropping drastically to avoid. Sauvy industrial field repair roller press bearing wear of case companies have a courtyard 150 - hefei 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.
