How to fix the 1. 5 mw wind turbine bearings? - bearing knowledge

As the global energy shortage, rising oil prices, environmental pollution and climate warming problem increasingly prominent, governments have to develop new energy as a way for sustainable development and cultivate new economic growth point of the great strategic choice. Wind power as a part of one of the important industrial equipment, has a pivotal role in the production. Thus spindle problems arise, it becomes very difficult. In general, for wind generator bearing wear, the traditional repair plan is: the overall demolition change, inlaid non-standard sets of repair welding and grinding. Remove the change to replace the new parts is the conventional way to repair, keeping regular consumable parts are also means of enterprise equipment management measures. When removing convenient, easy maintenance usually using this method. But given that offshore wind field is difficult to remove, time-consuming, laborious the repair mode, and shall not be commonly use. Low set non-standard sets of Mosaic non-standard sets of emergency repair measures is also a kind of common method. Biggest weakness is the machining accuracy is not high, and the wear parts of the contact area is finite, easy to cause secondary wear and greatly increase production safety hidden trouble. Low repair repair welding repair welding grinding machining technology is a traditional process repair process in one of the most common way, its characteristic is the repair of high precision. Its defect is the process of repairing for axial cause stress concentration or causing shaft bending deformation; Repair welding technology cannot avoid thermal stress problem, cause in the process of using the shaft crack and even broken danger, increase production safety hidden trouble. Now more and more enterprises realize that, has avoided with the method of repair welding for axial wear maintenance. Sauvy industrial carbon nano polymer application technology is how to the scene to repair the wear of the bearing? First sauvy industrial carbon like a cold welding technology of polymer materials, does not exist in the process of repair or producing heat, can effectively avoid the rotor shaft caused by thermal stress bending, deformation, good to protect equipment from damage of ontology, and on the depth of bearing a wear no requirements, in the process of repair is not restricted by bearing an uneven wear amount. Understand this, in the process of practical application of repair process there is a wide variety, this need according to the design of the equipment to determine the parameters and the operation characteristics and working conditions, all the repair process is the maximum guarantee under the premise of repair parts alignment. 1. Grind the bearing surface, clean, dry, solid, rough; 2. With anhydrous ethanol clean and repair parts, until boiled away; 3. According to the SD7101H blending material proportion of 1:2 mixed evenly; 4. Tooling wall clean, brush paint surface SD7000 stripping machine, evenly without omissions; 5. Shaft repair place daub SD7101H material, apply evenly to pore-free; 6. Rapid installation tooling, to SD7101H material curing; 7. Remove the tooling, clear SD7101H excess material, testing after repair trunnion sizes; 8. Adjust the shaft and bearing seat, switched on.
