Fans started work bearing a small part of the vibration function of centrifugal fan, but with longer running time, the dust will be uneven in the fan attached to the impeller centrifugal fan of the largest manufacturers, the gradual destruction of balancing centrifugal blower fan the bearing vibration gradually increased, once the vibration reaches the maximum allowed fan 11mm / s (with an amplitude value represents the maximum allowable value below), the fan must be shut down to repair (remove dust accumulation, redo balancing). Because this time is very dangerous, the user must not be forced to use. When approaching the danger fan vibration value, there will be vibration meter alarm. Fans can be divided by the use of classified material are several, such as steel fan (ordinary fan), FRP fan, plastic fan, aluminum fan, stainless steel fan blower, etc. can classify the direction of gas flow is divided into centrifugal, axial , oblique flow (Francis) and cross-flow and other types. (1) centrifugal fan. After entering the axial flow impeller fan mainly along the radial flow. According to the principle of centrifugal force such fan made products, including centrifugal fan, centrifugal blowers and centrifugal compressors. Use centrifugal fan, centrifugal fan, air-conditioning equipment provided by Hao Yang Hao Yang Air Conditioning Equipment Co., Texas.
