Any device in the course of work will have a different noise, I believe this is inevitable, but the most important thing is that we should find out the source of the noise, the noise will be reduced to a minimum, for galvanized sheet duct such equipment The same is true, then for reasons such equipment, generated noise and what it? Together to explore sources of noise galvanized sheet duct. Galvanized sheet only to find the source of the noise generated duct in order to more effectively solve this problem. Of course, the reason from this product has a lot of noise, we have to analyze specific issues. For the device is most likely where the noise is a turbine. Products due to transportation and installation reason is prone to turbo touch volute phenomenon, but this noise is easy to identify. In this case adjust the volute position on it. When installing no increase damping spring is also prone to noise. In this case it means increasing the damping. Further noise motor bearing bad will happen. In this case the only motor of change. I hope the above introduction to help reduce noise.
