Noise reduction, centrifugal fan environmental protection ideas

The dynamic noise of atmosphere is due to the unsteady gas flow. The noise generated by the mutual transmission of gases and gases and gases. From the mechanism of noise generation, that is, the disturbance of air flow. It is composed of rotating noise (air pressure pulsation) and eddy current noise. I like the wind noise atmosphere power machine is noise and eddy current noise change confusion effect; mechanical noise is important to the surrounding radiation through the chassis fan motor; electromagnetic noise and atmosphere dynamic noise and mechanical noise of relatively low.
Forward gas pressure side by side delivery of gas to a driven fluid machine. The utility model can be made into two types of right and left. The mission of reason and shorten the turbine machine is basically the same, just because the gas flow rate is low, the pressure changes little, not necessary to consider the individual gas volume changes, which do not shorten gas as fluid handling. Centrifugal fan air flow. The new installation will be too large, the fan after the new installation began to occur when running, too large or too small or the operation process, can use one of the following ways: adjust the flow speed to dispel change fan. The degree of opening and closing the door to adjust the flow control. Change the pipe resistance coefficient of flow regulating. Replace the pressure higher or lower wind machine adjust the flow.
