The noise problem has always had headaches.At present, there are still many noise reduction methods in the market.Especially in order to make peoples environment better, the noise reduction axis is designed.How to reduce noise on a shaft flow?Lets explain it.
Axial flow fan is a widely used fan, which is usually used for scenes with high traffic requirements and low pressure requirements.It is mainly composed of fan impeller and shell.The structure is simple, but the data requirements are high.The axis flow aircraft also produces noise during the operation.The current management method is:
First of all, in terms of pneumatic performance, minimize the impact of airflow impact and surface separation, and avoid or reduce impact noise and vortex noise.In design, avoid the sharp bumps and sharp turn of the stream.
The second is to be designed and installed on the immocoiled and exported muffler according to the principle of sound impedance loss.
The third is to set up a muffler at the exit of the axial flow fan, which can effectively reduce the level of noise.
Fourth, in order to prevent or reduce the dissemination of the bearing fans, a new sound insulation chamber has been built in recent years to place the shaft fans in a sound insulation room with sound -absorbing performance.
Fifth, the commonly used method in the repair of the blades is the perforation of the blades, which can reduce the noise of the vortex and make the air resistance pass.Because the separation of the vortex often occurs in the leaf exit, the work wheel leaves are usually perforated.The perforation method can make the high -pressure surface of some airflow flowing to the low -pressure surface of the blade, thereby promoting the separation point of the blades to move downward.This reduces the separation area and noise of the cross section of the leaf exit.
The low noise axis streaming mechanism becomes a square, beautiful appearance, and easy to install square holes in the wall; the exit wind is equipped with vertical vertical vertical windows to prevent outdoor rain and natural wind direction of indoor flow.obvious.
The above is the characteristics of how to reduce noise reduction and noise reduction axis flowers. I hope it can help you. If you want to know more about information, please pay more attention to us ——
