One of bearing wear online fast repair technology full disclosure

Bearing a wear online repair process according to different working environment and equipment problems in several kinds of plan, detailed introduced for everybody here USES the example of 'process of meticulous way, hope can solve the mystery in your heart! Or is the case in detail as to clarify the object. Enterprise a 4400 paper machine consumption line, 19 dryer operation side shaft head wear, bearing axial runout, often in a short period of time form the bearing inner ring fracture, have serious impact on normal continuous consumption to businesses. Drying cylinder diameter: 1800 mm, the speed: 400 m/min; Shaft head diameter: 220 mm, 1:12 cone; Bearing model: 23144 cak/C3W33. Dryer on the operation side of the shaft head bearing wear problem, can use the current effective treatment plan: 1, the overall change in end of the shaft head; 2, the in-situ repair stop shaft head wear parts repair process. Enterprise equipment management personnel on the basis of site operation space, acceptable downtime and overall change produced by the high cost and so on comprehensive thinking, finally sure sauvy technology is used to stop the repair. Ok, get into the business, below the sauvy technology is how to stop the online repair it? Sauvy engineer site only takes 10 hours to finish the bearing repair work, let's take a look at how they do it. The principle of first look at the models' repair bearing a said picture. A, enterprise 4400 paper machine consumption line field; B, remove the bearing show wear and tear parts, with the hand chain hoist cylinder, so the wear parts repair have a certain operation space; C, empty bearing test and confirm the shaft head wear quantity in detail, confirm the repair plan; D, using acetylene flame at the repair parts to stop baking oil disposal, remove all grease and impurities, until no sparks looks boring; E, look with polishing disc repair parts stop burnish disposal, especially the part of the hole or groove, ensure that after the disposal of the appearance of rough without dust; F, with a sample of some tapping pit stop operation, according to the positioning base to ensure the bearing after assembling the pre-tightening force of enough; G, tempered and daub sauvy SD7104 carbon nano polymer materials, full contact with the metal, make the data in the process of preventing present porosity; Coated sauvy SD7104 data H, after heat curing after forming, inspection repair appearance smoothness and brightness can reach request, check data compactness; I, device assembly process stop bearing assembly work, in the process of the device to ensure that the bearing clearance when you arrive at the normal operation of the technical request.
