3C tooth exhaust box noise prevention and control method
The 3C tobacco exhaust fan is generally used when the traffic regulations are high and the work pressure is low. It consists of centrifugal impeller and case. The structure is simple but the data information regulations are simple.3C tobacco chassis will also produce noise when running. This type of noise is very large, and the noise control of the 3C smoke chassis is also very good.
In the pneumatic type, in order to prevent or reduce the generation of impact noise and vortex noise, it is necessary to avoid the phenomenon of cyclone impact and the separation of the surface layer as much as possible.Turning.
Using the basic principle of impedance loss of sound, designing and using the exhaust pipes in the 3C tobacco exhaust fans, the noise of the 3C smoke exhaust fans and the sound radiation source of the exhaust pipes are reduced, and the noise reducing the noise reasonablyEssence
Setting sound absorption boards on the pipeline of the 3C tobacco exhaust fans can reasonably reduce the noise level.In order to better avoid or reduce the dissemination of the noise of the 3C tobacco firbox, the 3C smoke exhaust fans are recently settled into the sound -absorbing sound insulation room in order to better avoid or reduce the transmission of the noise of the 3C tobacco airbox.
To solve the update and transformation of the blades, it is generally the method of breaking the blade. This method can reduce the turning on rotor noise and make the frictional resistance.Methods, this method can reduce vortex noise and make frictional resistance well. Generally, the method of leaf cave is used to solve it.
Choosing the way to open the hole can allow some cyclones to flow into the bottom of the blade at the bottom of the blade, which can promote the leaf separation point to move downwards. This can reduce the separation of the horizontal section between the leaves and the leaves.Separation between each other.
