First, lubricate the bearings. "220V Cooling Fan" transport the most important parts is bearing a long time the lack of oil, will generate noise such high-speed rotation. Therefore, we only need a few drops on the fan bearing lubricant, sewing machine if you do not use to be replaced.
Second, fixed "220V Cooling Fan" fan. Loose fan blades are fixed on the bearing and bearing wear resulting in the gap becomes larger and so, so only need to remove the sub-sector, the screws tight button, then so firmly fixed, it will not shake. LED advertising vehicles of fans and we usually use the fan life is different, it is mainly the heat generated by advertising vehicles components for cooling, if there is no fan for cooling, it is prone to spontaneous combustion. Therefore, the maintenance of the fan with maintenance, or necessary.
Third, the polished "220V Cooling Fan" fan. In addition the use of poor quality cooling fan, in the production of this type of fan due to defects in workmanship, the center of gravity may not be in the blades of the axis, forming a "eccentric" and use over time, fans of "eccentric" phenomenon becoming more and more serious, it will not only produce noise, serious damage may also CPU. In this regard, can be removed altogether, and then thread hanging from its center position, let it sink still to see which direction to put an end to sink in light grinding a few times, and then tested, has been After the fan can be installed in a horizontal position and then go to.
