Common faults of cooling fan bearings and noise during operation
Common faults of cooling fan bearings and noise during operation u003cbru003e u003cbru003e u003cbru003e Rolling bearings are allowed to have a slight running sound during operation. If the sound is too loud, abnormal noise and impact sound, the bearing will be faulty, and the cause of the noise generated by the bearing is more complicated. One of the bearings and the shaft core will cause the axis Deviated from the correct position, the bearing produces abnormal noise when it is rotating at high speed. When the bearing is fatigued, the metal peeling on the surface will also increase the radial clearance of the bearing and produce abnormal noise. Some external bearing lubricants are insufficient to cause dry friction and bearing rupture. And so on will produce abnormal sound. Wenling Tongchi Automobile Air Conditioning Manufacturing Co., Ltd. uses high-quality principle materials to reduce the abnormal noise of the cooling fan.
