Summer is coming, and cooling fans have become best-selling products! Although the appearance of the cooling fan seems to be similar, there are great differences between different types of cooling fans. Even if it is a few more fan blades, or the assembly structure is different, its functionality is also different. Do you know how big the difference is between cooling fans?
Suzhou Santian Precision Mould Co., Ltd. will answer this question for you!
1. Oil bearing fan
Oil-bearing bearings are sleeve bearings that use sliding friction, and use lubricating oil as a lubricant and drag reducer. It has a relatively low cost and a simple process. Of course, the price is the cheapest and the quietness is also good.
2. Magnetic levitation fan
The magnetic levitation bearing fan is actually a self-contained oil bearing fan. It uses the principle of magnetism. The magnetic induction line is perpendicular to the magnetic levitation line, and the shaft core is parallel to the magnetic levitation line. The shaft core is propped up in the direction of the anti-magnetic levitation line to form the whole rotor floating running track.
3. Single ball fan
The single-ball fan is a combination of sliding friction and rolling friction, which is actually a combination of a ball bearing and an oil bearing. This kind of fan is not expensive, and overcomes the shortcomings of short life of oil-bearing bearings, and has a long service life.
4. Double ball fan
The price of the double ball fan is second only to the magnetic levitation fan. Because of the double-layer ball structure, there is no oil leakage problem, and the sealing of the bearing is best not easy to aging and wear, so its life is the highest, and many violent fans use double balls.
