It is the current undesirable principal element of Wind turbines bearing lubrication that plug, which causes a whole set of lubricating system paralysis,.In addition, waste and old grease cannot and
When discharge, waste and old grease and abrasive dust is caused to form obstruction full of bearing cavity, hinder the smooth injection of fresh grease, make bearing
Ball surface is difficult to form tempered oil film, and the new grease of lasting injection bearing inner cavity just bursts oil sealing at oil inlet to be caused to let out
Leakage, bearing not only lose lubrication, but also for a long time with rotten waste and old grease and abrasive dust friction, it is long by bearing damage therefore true
Protecting bearing lubrication system normal operation just seems very urgent.
Since oil discharge outlet oil duct is longer, the resistance that grease discharge need to overcome is larger, and base bearing waste oil can not be arranged from oil discharge outlet
Go out.And the pressure voltage of oil sealing is smaller, long-term base bearing waste oil can not be discharged from oil discharge outlet, with bearing cavity pressure rise, be given up
Oil is extruded at oil sealing, and manual cleaning is needed when grease is excessive, adds maintenance cost；A small amount of base is only had collected in oil-containing groove
Plinth thin oil, a large amount of adhesion agents are then retained in Bearing inner, and long meeting saponification is hardened, and long will seriously affect the use longevity of bearing
Life.
