Selection of Small DC Axial Fan Manufacturers
Date：2020/2/25 Views：1831 【BACK】
At present, the market affecting axial flow fans is very large, and the current cooling technology is becoming more and more important with the function of auxiliary cooling fans of precision instruments. Therefore, it is very important to choose a good cooling fan for the relevant instruments. How to choose a good small DC axial fan manufacturer in the vast market?
1. Select a good DC axial flow fan manufacturer to choose from the brand. Choosing a good brand fan means selecting quality, which is an important guarantee for the fan quality.
Look at the strength of DC fan manufacturers, when choosing the best manufacturer reference, understand the strength of the manufacturer ..
3. The appearance of the whole surface should be relatively thick, relatively pure color (especially black, the color of the fan is not important), there is no burr on the edge of the box leaf, and the thickness of the leaf (very important, because it is too thin and easy to break) can be seen without significant deformation.
3. Because bearings are divided into ball bearings and oil bearings .. Ball bearings have long service life and low noise, but the price is very expensive. The service life of the bearing is one-third shorter than that of the ball bearing. Some noise (more than one year) may occur after a period of use, but the price is cheap. If the price of the ball fan is similar to that of the oil-filled fan, then don't buy old or outdated ball bearings .. The service life of the bearings (except oil bearings) in the new products jointly promoted by the manufacturers will not exceed that of the ball bearings, and there will be noise during later use. ..
After the fan operates normally, choose to let the fan operate normally.
One. It should only hear the sound of the wind (there may be some high-speed electromagnetic sound), if other sounds indicate that their quality is not very good. If the fan speed does not exceed 3500RPM, the fan speed is not very high 7 cm, but the description of the wind of many fans is poor.
B. hold the fan with your hand to feel its vibration, and change different angles. the feeling of the rear hand is the same, which shows that the vibration of the fan is very good. if there is vibration, it may cause co-vibration on the chassis. before, some people made loud noises when starting the fan, which was mainly caused by vibration when starting the fan.
C stop the fan from rotating by hand (do not break the fan blades) for about one minute, touch the center of the fan by hand to feel its temperature. if the temperature is high, it is not qualified.
