Repair welding technology fix axis wear solid?

After repair welding technology is to use metal repair welding repair using professional equipment at site to stop the car, milling, planing, grinding, or artificial grinding, restore restore is worn shaft size. Repair repair welding machine has the advantage of high precision, but its shortcomings are obvious: first of all about fan and other large equipment shaft wear problem can't stop online repair, demand for shaft overall demolition, after a heavy machinery and transport back to manufacturers stop maintenance equipment consumption, this overall demand cycle is about 20 days, or even longer, disassembly and transportation would greatly increase the capital to repair and repair cycle, low comprehensive cost performance, greatly affect the normal consumption of the enterprise, increase the maintenance capital; Second thermal stress problems of this technology, easy to cause shaft bending deformation, cracks may produce welding parts at the same time, formation using infix axis of risk; Finally repair welding repair generally used artificial ground disposal at present, the disposal way is the premise of repair parts did not wear datum, the worn parts as a benchmark, in an application module stop artificial abrasive machining, using artificial grinding process is difficult and repair for a long time, at the same time, after repair interface is difficult to reach more than 50%, for later consumption form the safe hidden trouble. Based on the above mentioned, we can find repair welding and machining axis wear repair aspects indeed, there are many disadvantages that in addition to the process there is no better technology to deal with shaft wear and tear problems? The small make up for everybody introduced a new technology of shaft wear repair - — Sauvy carbon nano polymer materials, hope some help to you. The advantage of the information on-line repairing shaft wear 1. The material has good cohesive force, compressive properties and have metal comprehensive mechanics performance of elastic deformation and so on to complete the online repair, repair of high efficiency, short time to repair. 2. The data itself has the compressive strength, bending, stretching rate and other comprehensive advantages, can effectively absorb the impact of the external force, great resolve and offset the bearing of the shaft radial impact, and prevent the possibility of a gap appears, also prevents the device formed by gap increased wear. 3. The technology is similar to a cold welding technology, the online repair 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. 4. Use after the repair process does not produce metal fatigue wear and 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. Quick fix axis wear problem show 1 case. On both sides of some cement enterprise 710 kw motor spindle bearing wear, the speed of 990 r/min, uneven wear depth of more than 1 mm, bearings for the NU series bearings, normal operating temperature 50 ℃ or so, both ends fixed. 2. Some group subsidiary company German roots blower MG60S bearing wear, rotating speed of 1485 r/min, journal of 70 mm, wear width 30 mm, 2 - wear depth 3 mm, operating temperature about 100 ℃. 3. A large group enterprise bearing wear, bearing interior diameter 680 mm, bearing width 163 mm, 2 mm wear size.
