Dust into the wind turbine bearing,increasing noise

In recent years, the major bearing manufacturers in terms of the radiator's new technology, Wind turbine bearing , such as magnetic bearings, water bearing, bearing core, to Fu bearings are also on top of the basic forms of bearings made to improve the operation of the principle did not change .

Ordinary air-cooled radiator oil bearings and ball bearings are mainly used.And this bearings over time, due to the oil seal (computer radiator products are impossible to use high-grade seals, generally is ordinary paper seals), insert ball bearing ,oil will gradually evaporate and dust will enter the bearing, causing the fan slow speed, noise increases and other issues, but also because of a serious bearing wear caused by severe vibration caused by eccentric fan. These phenomena, Deep groove ball bearing either open seal refueling, or to purchase another new fan only eliminated.
