As the global energy shortage, rising oil prices, environmental pollution and climate warming problem increasingly prominent, governments and the way to carry out the sustainable development of new energy as a search and cultivate new economic growth point of serious strategic choice.
Wind power as a part of one of the important industrial equipment, has a minor role in consumption.
So the spindle present problems, it becomes very difficult.
Ordinary, 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 change the new parts is the conventional way to repair, keeping regular consumable parts and equipment management measures in the wrist.
When removing bento, maintenance are usually using this method.
But given that offshore wind field is difficult to remove, time-consuming, laborious the repair mode, and shall not be used.
Low set non-standard sets of Mosaic non-standard sets of emergency repair measures is also a kind of common wrist.
Biggest weakness is the machining accuracy is not high, and the wear parts of the contact area is finite, easy to form secondary wear and greatly increase the consumption safe 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 easily in the process of repair of axial stress concentration or form the shaft bending deformation;
Repair welding technology to prevent the problem of thermal stress and formation of shaft using present in the process of crack and fracture risk, increase consumption safe hidden trouble.
Now more and more enterprises realize it, used to try to prevent with the method of repair welding stop 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 nano polymer material similar to a cold welding technology, does not exist in the process of repair or produce heat, can effectively prevent the rotor shaft formed due to thermal stress bending, deformation, good maintenance equipment from damage of ontology, and on the depth of bearing a wear no request, in the process of repair is not restricted by bearing an uneven wear amount.
After know that, in the process of practical application there is a wide variety of repair process, the requirements on the basis of the design parameters and operation characteristics and working condition for sure, all the repair process is the maximum level guarantee under the premise of coaxial degree of the repair parts.
