Research on Fault Verification Technology of Centrifugal Fan
Fault injection test and data analysis are carried out for centrifugal fans,and the effects of impeller unbalance,rotor unbalance and bearing fracture on vibration data are described.The change rule of eigenvalue is studied,and the effective fault signal is extracted,which lays a foundation for on-line monitoring of centrifugal fans,and is of great significance for the operation and maintenance of centrifugal fans.
