Where is the noise of the vortex blower mainly from?
After the vortex fan is turned on, the noise will follow, so where is the big sound coming from?
No matter what kind of equipment, as long as it is not in a static state, the work is inevitable, and the sound is inevitable, but the sound is different, and it is different.
For our fan products, the main sound comes from air flow noise and mechanical motion noise. Baidu Encyclopedia entry, also given to explain, the above is said:
Where is the noise of the vortex fan mainly from?
First, air flow noise:
The noise generated during the flow of gas is mainly due to the unsteady flow of the gas, that is, the turbulence of the gas flow, the noise generated by the interaction between the gas and the gas, and between the gas and the object.
The characteristics of airflow noise are also related to factors such as the pressure and flow rate of the airflow. Common airflow noise such as fan noise, jet engine noise, high-pressure boiler venting exhaust noise, etc., please search for Baidu.

Second, mechanical motion noise:
It includes the noise of the fan bearing, the sound of the motor running, the wave noise caused by the rotor, etc. In addition, the pipe components connected to the fan, such as the deflector, elbow, reducer, etc., are unreasonably arranged. Produces noise. This type of sound is different from aerodynamic noise.
From the mechanism of noise generation, it mainly consists of rotating noise and eddy current noise.
Knowing the principle and root cause of noise, then, for noise reduction, you know where to start.
For the mechanical noise has been optimized in the early stage, then for the air flow noise, the silencer can only be installed on the external equipment, which is the stainless steel silencer we usually use.
