Cooperating relationship problem: No matter how high the accuracy of the parts is in the processing process, it will never reach 100% of the mating surface of the part. Normal fatigue wear of metal, which is an inherent characteristic of metal itself; Operation and maintenance problems: including poor lubrication of bearings, high operating temperature caused by blockage of the cooling system, loosening of fastening devices, etc.

For a long time, the solutions for bearing wear of high temperature fans are nothing more than the following: repair welding and processing, electric brush plating, thermal spraying, repair welding machining, thermal spraying repair process cannot be implemented online repair, although electric brush plating can achieve online repair , But the requirements for the wear depth are more stringent. Is there a better solution besides that? Soleil carbon nano polymer material technology can realize the wear of high temperature fan bearing position.

Installation problem: The installation position of the bearing cannot be well controlled or the clearance of the bearing cannot be effectively controlled during the installation process, resulting in the bearing cannot be in an optimal state during the running process, and the running resistance increases, the temperature rises, and the torque More acts on the mating surface, causing relative movement between the inner ring of the bearing and the shaft surface, causing wear of the shaft. Under the premise of normal maintenance of the equipment, the service life after repair is even higher than the service life of new parts.

Therefore, the small bearing surface of the mating part is also one of the root causes of metal fatigue and wear; There are many reasons for high temperature fan bearing wear, which can be summarized as the following points: This technology uses the material's unique mechanical properties and targeted repair technology to repair the wear of large shafts such as fans on-line. Case show: high temperature fan: main shaft diameter is 160mm, speed is 1500r/min, the bearing position on the transmission side is worn, the wear width is 80mm, and the wear depth is about 0.

From the microscopic view, the mating surface of metal can only achieve 30%-50%. The advantages of this technology for repairing high temperature fan shaft wear are as follows: Good adhesion, compression resistance, wear resistance, and comprehensive mechanical properties such as elastic deformation of metal to Wholesale Mechanical ball bearing Factory achieve online repair, high repair efficiency, and no A large amount of equipment needs to be disassembled, and the repair is usually completed within 8 hours; This technology is similar to a cold welding technology, which does not generate high temperature during the online repair process, and protects the equipment body from damage, and the repair process It is not limited by the amount of unilateral wear of the shaft; After repair, there will be no metal fatigue and wear during use.5mm.
