Regular maintenance of SKF bearing stainless steel cleaning and inspection way

Demand stress is that it is main link stainless steel bearing is smooth and clean. So when we on bearing stop before the raid, you should clean the SKF bearing a brief, and then remove the perimeter of the bearing parts. It is cowardly of oil seal parts, fruit and was raided and demolition demolition demand cockiness special be careful, don't be too much work, so as to avoid damage to constitute part. Then carefully raid bearing oil seal and its surrounding parts, if not present a bad disease, be sure to switch off and bad seal will cause bearing damage, make the stainless steel bearing cloud differences, constitute the equipment downtime. Trunnion adhesion and avoid direct contact with bearing bush attack a border smooth performance. Affect the friction pair friction compatibility of data elements are: ( 1) As deputy information on metallurgical alloy difficulty levels. （ 2) Data and affinity to smooth agent. （ 3) As a deputy data in the condition of no smooth friction factor. （ 4) The microstructure of materials. （ 5) Thermal conductivity of materials. （ 6) Data can appearance size and characteristics of the oxide film. The local process is imported bearings of the main working procedure, the process of inspection is the main difference in locomotive repair industry manufacturing industry. Into repairing stainless steel bearing can continue to use, how ability to satisfy the request, will be central to the local process to deal with the problem. Before cleaning, first check the grease to keep the status of the basin, confirming and judging the validity of the current refueling, fill oil system. For hair second oil state of physical and chemical examination, qian, harden, agglomerate, oil analysis, thinning, color change, confirming and judging the rationality of the aging oil change period, adjust the oil change period and fill oil system. Cleaning degree is to restore a stainless steel bearings SKF bearing and stop check measure the necessary link of bearing parts. Try to erase the old dirt before cleaning grease, pay attention to don't turn the bearing in the process of operation, in order to avoid collapse into one strain of impurities get lost in the process of working face; Move when the bearing to should take put down gently, to avoid bruising. Cleaning work is common in to stop a diesel oil pool, diesel heated to 80 - - 90 t, the pump pressure, circulation bearing. Please wash the pool bottom should have metal mesh, avoid things after SKF bearing from falling into the pool. Pool of diesel filter regularly, add new oil, liquidation sunken temple, to insist on diesel to reach the purity of the process rules. Cleaning fluid to stop using mixed corrosion medium. Traditional flush or high temperature ( With a mixture of steam and water spray, slightly beyond the oil drop point) Cleaning process, just can meet the cleaning quality request, the new things, also need not deliberately. Cleaning quality of imported bearings, is the clean degree scale yes stainless steel bearing. Railway vehicle department after repeated deliberation, real face, must process the heap is SKF bearing in thousands net gasoline after cleaning, use pool paper filtration, drying, weighing, its residual ash content is not more than 20 mg, in railroad engineering department to facilitate control.
