During the inspection, we find that some problems exist in the bearing housing, bearing housings used in order to better protect the fans, but a careful examination, we found that sometimes spill issues bearing box will appear, but the cause of the bearing housing drain factors more oil, we also need to gradually analyze, for example, pipe line interface Mifengbuyan, lubricate the bearing box is too high, then the amount of oil, seal fan of these reasons can cause damage to the fan bearing box appears leak phenomenon oil spill caused by the amount of different reasons are different, and because of the different types of wind turbines, plus the difference between the use of the specific reasons for the problem arising from the oil spill is also different, so we face the problem of the bearing housing oil spill time, we also need specific conditions.

In addition to the bearing housing problems, we also found that the leakage problem of the hydraulic cylinder, hydraulic cylinder leakage and sealing of the main reasons is related to Mifengbuyan, or the gap is too large, the level will produce hydraulic cylinders combined with lax oil spill issues in addition to these reasons, we can not ignore the problems caused by oil leakage, so when we solve the above problems, and do not forget the quality of oil were detected only in passing situations oil Next, in order to ensure that the effect of the fan.
