Why the micro dc fan noise is big

Micro dc fan use fixed number of year for too long, can make a big noise gradually, some with mini fan products, is not fixed, such as will swing up and down, left and right rotation, etc. , for this kind of product, often have the customer would ring why mini fan are put forward. For mini fan, especially the super mini fan, fan operation is very fast, at a speed of more than 5000 revolutions per minute insist on highly balanced rotation, bearing a few mm thick, and the bearing through the bearing in high speed rotation, if we use external force to swing, high-speed operation of the blades will be forced to tend to one side, and make the axial bearing friction produces sound, that was only for our products to stop spending on three sides listen to reason. The voice also has a certain relationship with bearing, oil bearing is a suspension structure, swinging sound will be bigger, the structure of the double ball bearing is a fitting, will be better, so that customers in the selection, for such products can also went up from bearing to make choices. When our mini fan is used under the environment of high temperature, oil bearing easily by high temperature to dry, copper shaft under the condition of without oil, the sound will become big, again with inhalation of dust, the noise will be more and more about the need to ensure that the mini fan for years cannot present noise products, initiative with fan, double ball bearing type with high temperature resistance, dustproof function. That is related to the cause of micro dc fan noise big, hope to be of assistance, shenzhen YiRongChuan electronic technology co. , LTD is a professional research and development to produce a cooling fan, cooling fan, dc fan, dc fan cooling fan peng brand manufacturers, free proofing, directly or indirectly from two days out of the sample, the quality is good, service first-class, farewell everyone to come to understand.
