What factors influence the noise level of industrial cooling fans
Date：2019/11/23 Views：2549 【BACK】
The noise of the cooling fan is the noise generated by the cooling fan during operation. It is affected by various factors and is expressed in decibels(dB).
When the radiator fan operates with a noise of less than 20dB, it is an ultra-silent fan. When the noise is less than 40dB, it is the sound level that everyone can accept when sleeping quality. So what is the harm to the noise level of the radiator fan? Let's give examples one by one.
1. Thermal fan bearing system: General bearing system noise level double ball bearing noise, followed by hydraulic bearings and oil bearings. The reason is that the friction and collision between the running shaft and the bearing are the main factors that affect the fan noise.
2. The speed of the cooling fan: The higher the speed of the cooling fan, the greater the wind, the greater the noise. We can not overcome this problem. We must rely on the actual cooling requirements of the equipment.
3. Installation of cooling fans: When installing cooling fans, ensure that there is enough space between cooling fans and obstacles, and there is no room to install cooling fans.
