Small Wireless Charging Ventilation Cooling Fan

Heat dissipation fan for a long time, sometimes there will be some small problems, such as slow speed, noise increase, it is likely because the lack of lubricating oil bearing lead to the fan is not smooth, wind speed is slow; Bearing friction with other parts, resulting in noise. At this time, we need to check whether we need to add lubricating oil to the fan bearing. Cooling fan adding lubricating oil steps are as follows: First tear the plastic stickers on the fan axis, pay attention not to tear all, as long as the bearing exposed, because if all open, it will make the stickers lack of viscosity is not easy to stick back. At this time, we can see that the bearing is dry and there is no lubricating oil. The reason for the noise is here. After tearing the label, we can pry open the central oil seal cover with small tweezers, take one or two drops of lubricating oil, carefully drop it on the fan bearing, and turn the fan blade once for each drop, so that the bearing is fully lubricated. Usually you don't need to add too much, just two drops. Because too much may lead to overflow, sticky but easy to pick up dust, affect the normal operation of the fan. After the lubricating oil is added, we put the oil seal cover in place and put the sticker back in place. Then blow on the fan blade, see if it can run up, if not to prove that the inside is dry, need more lubrication, until flexible rotation so far. 

To sum up, whether to understand the cooling fan lubricating oil work.
