The popularization of the definition of DC fan

Over DC voltage and electromagnetic induction, the electrical energy is converted into machinery to drive the fan blades to rotate, collectively referred to as DC fans. working principle Simply put, depending on the continuous switching of the coil and the IC, the induction magnetic ring drives the fan blade to rotate.

The popularization of the definition of cross-flow fans

Cross-flow fans are small high-pressure centrifugal fans with forward-facing multi-blade impellers. The gas enters the impeller from one side of the outer edge of the rotor, and then passes through the interior of the impeller and is discharged from the other side, where the gas is subjected to the force of the blades twice in the impeller. Under the conditions of the same performance, it is small in size and low in speed. Compared with other types of low-speed fans, cross-flow fans have higher efficiency. Its axial width can be selected arbitrarily without affecting the flow state of the gas, and the gas still maintains a uniform flow over the entire width of the rotor. Its outlet section is narrow and long, suitable for installation in various flat equipment for cooling or ventilation.

What is a Ball Fan? Let's take a look!

What is a ball fan? We have made a brief introduction to this issue before, but found that there are still many customers who do not understand. Just take this opportunity to explain it to you today. Hope it can bring good help to relevant people. A ball fan is a fan whose bearing uses balls. It has the advantages of wear resistance and longer life than oil-impregnated bearing fans when in use. But the cost is higher. When the ball fan is in use, you also need to understand that it uses round metal balls to run, so it belongs to point contact, so it is easy to activate the operation. In addition, the ball bearing is used with the spring, so the metal ring outside the BallBear is supported on the top of the spring, so that the weight of the entire fan blade rotor sits on the ball bearing and is indirectly supported by the spring, then it can be used at this time. Portable products in different directions and angles, but still need to prevent falling. Of course, if you pay attention to these, it is also to avoid damage to the ball bearing, which will cause noise and reduce service life. If you explain it like this, everyone will understand. In addition, what we also need to know here is that the ball fan is similar to the bearing, but there is a metal ring sleeved on the bearing. Its balls are good, but if the quality is poor, ordinary users like us can't fix it. If the sound of the bearing is loud during use, remove it and add some oil. When the ball fan is used, its advantages are also relatively clear. For example, it is an improvement on the traditional oil-impregnated bearing. Manufacturers also use a combination of sliding friction and rolling friction in production. In fact, it is to use a ball bearing with a The oil bearing method reduces the cost of the double ball bearing, and the staff should understand that the rotor and the stator are lubricated with balls and lubricating oil, then the ball fan is also equipped with lubricating oil. It overcomes the short life of the oil-impregnated bearing, which makes its operation unstable, and the cost increase is extremely limited. The ball fans also absorb the advantages of oil-impregnated bearings and double ball bearings, and increase the service life of the bearings to 40,000 hours, but there are still room for shortcomings. For example, its disadvantage is that after adding balls, the running noise has increased, but it is still smaller than that of double ball bearings. Here are mainly engaged in brushless fans, cooling fans, DC blowers, micro fans, AC fans, waterproof fans and other products. It can be seen that their product categories are really very large and quite complete, so that they can meet customers in different industries. You can definitely work with them if you want to order. The content of the above article is what Xiaobian introduced to you about what is a ball fan. If you don't know much about these, then read it quickly.
