Vibration Control of Belt-driven Centrifugal Fans in Nuclear Power Plants
Starting from the route causes of vibration of belt-driven centrifugal fans,i.e.,structural resonance and rotor unbalance,the analysis of vibration transmission path is carried out,which determines the over-standard excitation source of motor vibration.Then the method of dynamic balance is used to reduce the residual unbalance of the fan,so as to ad-dress the over-standard motor vibration.
