The cause and the treatment method about dc fan noise

by:TOCH     2021-01-27
Dc fan, for you, strange and familiar stranger because of its name, familiar with because we often come into contact with, often in our apart when old equipment or maintenance of household appliances, we can see the figure of it, then the following by tong chi dc fan manufacturer to explain the micro dc fan noise the cause and the treatment methods.

before this, we must first understand what factors, micro dc fan noise and

1. Rotational speed. Dc fan speed faster, the greater the fan, the greater the noise out of course

2. Bearings. Dc fan bearing simply divided into two kinds, one kind is oil, is a ball, under normal circumstances, the ball bearing fan was bigger than the oil bearing of the fan noise.

  3. The air flow. Fan blades during the rotation, is the resistance in the air, the faster the rotation, fan leaf area is larger, the greater the resistance, so the noise will be larger.

4, friction. Fan use time is too long, the fan will appear more box, vibration, etc. In some cases, this will cause the fan blades and fan casing collision or friction, resulting in a noise.

the micro dc fan noise processing method.
1。 According to their own actual situation to choose suitable for use of fan specifications and parameters, not blind pursuit of speed. 2. On a regular basis to clean fan dust and gas to reduce the friction between the fan. 3. Select excellent quality products, the best is a brand, because the brand is the quality and after-sale protection, do not covet is cheap. 4, between the fan and fixed end mat, rubber sponge or cotton cloth to reduce fan high-speed rotating vibration caused by noise, and there are many methods, in which I can not tell one by one.

that is caused by the micro dc fan noise factors and some processing methods, hope to be of help
