Elevator bearings wearing online fast repair of power enterprises to shorten downtime

On August 25, 2018, conch cement inspection personnel in the process of normal inspection found head wheel bearing ring, discriminant for bearing damage. Bearing damage incurred head round sink and bearing gland and happened to stop after wear, overhauling found damaged bearing inner ring for shaft wear and tear. The double drive bucket in library roof platform, 45 meters high bucket weight of more than 30 tons, adopting off-line repair or change driving wheels are finished in a short time. Elevator shaft wear problem for rapid processing, enterprise equipment as a person through the conch branch department technical exchanges between understand to sauvy on-line maintenance technology, and rapid and sauvy collaborate. Sauvy engineer for this problem, swiftness, technical discussions, remove the reducer in the enterprise in time sauvy engineer overnight work overtime according to wear trunnion sizes customized processing sauvy tooling, and arrived at noon on the 26th to enterprise site equipment. Sauvy axial wear online fast repair technology analysis: sauvy carbon nanometer polymer materials technology is a kind of information technology, is the comprehensive performance of application data and targeted repair process repair worn parts, parts restore restore size tolerance and meet the equipment operating condition, to reach the purpose of equipment persistent application. According to the bucket trunnion sizes and wear situation certainly sauvy tooling process, site operation steps are as follows: 1. On the basis of trunnion sizes processing the sauvy tooling; Hoist bearing wear 2. Liquidation of working face, lifting the drive shaft, show repair parts; 3. For repair parts clean oil removal, use the oxygen acetylene will stop bearing for oil removal, until the oil carbonization; 4. With grinding wheel piece of rear axle shoulder high polished clean up; 5. Bearing a front-end application full size parts as a benchmark, eliminate the shaft of polishing metal high; 6. Test and tooling until the parting plane complete closed up and down; 7. After test and tooling qualification, tooling clean the liquidation and brush SD7000 release agent; 8 coated sauvy SD7101H data. Mixed right amount sauvy SD7101H carbon nano polymer materials, average closely along the axial surface coating; 9. Hurtling installation tooling, fastening bolt to parting surface crack; Device tooling 10. Remove tooling data after curing, clearing redundant information. 11. After measuring repair trunnion sizes; 12. According to the request of hot load bearing.
