An enterprise in a large field of 15 year annual equipment maintenance period, during this period found two great workshop two mill reducer bearing the condition of the oil chamber, then open the view, find the bearing chamber was wear and bearing outer ring, prior to this enterprise has found that the equipment running in bearing chamber wear bearing outer ring, patch repair that enterprises choose to use cold welding technology at that time, but using the technology to repair only use for less than three months after appears falls off, use effect is unsatisfactory.
After the enterprise equipment management personnel for repair measures, inadvertently awareness of sauvy carbon repair technology of polymer materials, try holding the mentality and sauvy solutions center engineer contact, in sauvy engineers understand the related equipment operation parameters immediately sauvy industrial solutions center after a meeting to discuss the solution, 10 minutes will reducer bearing chamber of wear after repair plan for enterprises, enterprises promptly said recognition of repair plan, enterprise production urgently, so sauvy industrial sent two engineers with the fastest speed drive to enterprises to repair equipment.
Traditional repair process and sauvy reducer bearing chamber carbon nano polymer materials to repair worn technology compared to cold welding repair process: for bearing housing repair, indoor use of cold welding process will patch welding in bearing, its welding point contact, the welding strength is not high, and the contact area is less, once the bearing outer ring run poor contact is likely to cause the outer ring, will cause cold welding strips off, bearing chamber to wear again.
Brush plating repair technology, its advantage is that you can realize the online repair, its shortcomings are very obvious.
The brush plating coating brush plating technology is limited by the amount of wear, general electric brush plating coating to brush plating thickness less than 0.
2mm。
When wear is greater than zero.
2 mm, the brush plating efficiency drops will be multiplied, and too thick brush plating, in the process of using brush plating are easy to fall off, short service life.
For wear depth of 2 mm, unable to realize online brush plating brush plating technology.
Repair welding machine repair process: enterprises to adopt repair repair welding and boring process, due to the environmental conditions, to meet the requirements of accuracy, no guarantee that the good cooperation from the bearing outer ring and the bearing chamber, there is no guarantee that repair effect.
Sauvy industrial carbon nanometer polymer repair technology: using carbon nanotubes unique mechanical properties of polymer materials and targeted mill reducer bearing housing repair process of the wear and tear, for wear reducer bearing chamber, at both ends and the middle is unworn datum.
Benchmark size in good condition, sauvy industrial carbon nano polymer materials can be applied directly to a specific part of the match, use a datum for two repair, can reach 100% of the mating surface, meet the operation requirements of the equipment.
Sauvy industrial carbon nano polymer material to repair the bearing chamber wear under repair with high efficiency, which can realize the online repair, the repair is not only repair the equipment damage parts and sauvy engineers need to find the cause of damage of the parts, to avoid the same problems again, comprehensive repair cost is low, to the enterprise equipment maintenance maintenance provides a powerful solution, greatly reduce the production cost of enterprises.
Sauvy remote operations command center with sauvy sauvy equipment maintain traceability system engineer at the scene of the equipment maintenance by using AR intelligent glasses sauvy remote operations command center, sauvy solution center engineer sauvy remote operations system to check the equipment maintenance field of real-time information, jointly by sauvy solution center engineers to find and solve equipment problems, and improve the repair scheme according to the field situation, real-time fully involved in the repair of equipment in the process to make the whole maintenance process more perfect, repair the results more reliable.
At the end of the maintenance, sauvy engineer will help enterprises build equipment archives in sauvy equipment maintain traceability system, only need a simple qr code, it can realize the daily tally of production line equipment, data acquisition and maintenance of archives information management, equipment designed scan qr code through a mobile operator, immediate rapid maintenance information query, record the daily check data and equipment information, for abnormal operation of the machine automatically to inform, to minimize the risk of unplanned downtime.
Reducer bearing chamber wear site operation steps are as follows,
1)
On-site inspection surface wear, measurement benchmark anchor point;
(
2)
Clean the oil removal, for repair parts bearing for oil removal with oxygen, acetylene, until the oil carbonization;
(
3)
Surface treatment using the grinding wheel piece to burnish of bearing chamber surface coarse;
(
4)
Using anhydrous ethanol cleaning a bearing surface to the oil pollution, dust;
(
5)
Harmonic sauvy carbon nano polymer materials SD7101H;
(
6)
Daub sauvy carbon nano polymer SD7101H to wear and tear of the surface of the bearing chamber;
(
7)
Use blade feet along the unworn blow grind processing datum;
(
8)
Using a heat gun heated, accelerate the curing time and improve the material performance;
(
9)
Remove excess material after curing materials and measurements;
(
10)
Empty bearing test, check whether high, check the contact area;
(
11)
Daub again in bearing chamber material, when it is assembled on the bearing daub SD7000 demoulding agent, an assembly in place;
To complete the repair.
