Everyone may experience fan oil leakage and oil rejection when using a cooling fan, which not only affects the normal use of the cooling fan, but also causes pollution to the surrounding environment and also affects the aesthetic appearance of the fan. So what are the reasons for the leakage and oil rejection of the cooling fan?

1, bearing problems:

The oil-retaining bearing used in some cooling fans has its own porous structure. This type of bearing takes a long time to use. The lubricant in the bearing sleeve easily leaks out, the noise also increases, and it will become contaminated with other accessories. The bearing is easily worn. Shorter service life.

2. Lubrication problem:

There is oil leakage from the cooling fan. The main reason is that excess oil has caused excess oil to overflow. In addition, if the used lubricating oil is too low, the quality is not good, and the viscosity is not high, it is easy to cause the phenomenon of oil rejection when the fan is running.

3, sealing problems

The cooling fan cover usually has a sealed label to prevent oil spillage. Therefore, after tearing off the label and adding lubricating oil, there is no label re-adhesion, or the label is not sticky enough, it may cause the cooling fan oil spilling.

The above content is about the reasons for the appearance of oil leakage and oil rejection in the cooling fan. I believe we all understand it. In the process of using the cooling fan, some minor details need to be taken care of, and the maintenance of the cooling fan is well done, so that the fan can be well prevented from some minor troubles and the best use effect can be achieved.
