Vortex blowerWhere does the noise mainly come from

After starting the vortex fan, the noise comes with it. So where is the main source of such loud noise.

No matter what kind of equipment it is, as long as it is in a non static state and working, it is inevitable that it will produce sound, but the sound will vary greatly.

For our fan products, the main sounds come from air flow noise and mechanical motion noise. On the Baidu Baike entry, there is also an explanation provided, which states:

Where does the noise of the vortex fan mainly come from

1、 Airflow noise:

The noise generated during the process of gas flow is mainly due to the unstable flow of gas, that is, the turbulence of the airflow, and the noise generated by the interaction between gases and objects.

The characteristics of airflow noise are also related to factors such as airflow pressure and velocity. Common airflow noise such as fan noise, jet engine noise, high-pressure boiler exhaust noise, etc., please search on Baidu for more information.

2、 Mechanical motion noise:

It includes the noise of fan bearings, the sound of motor movement, the fluctuation noise caused by rotor drive, etc. In addition, if the pipeline components connected to the fan, such as guide plates, elbows, and variable diameter pipes, are not arranged properly, they can also produce noise. This type of sound is different from aerodynamic noise.

From the mechanism of noise generation, it is mainly composed of rotational noise and eddy current noise.

Knowing the principle and root cause of noise, then we know where to start when it comes to noise reduction.

For mechanical noise that has already been processed and optimized in the early stage, the only solution for air flow noise is to install a silencer on external equipment, which is the stainless steel silencer we usually use.
