Why do blowers need to be balanced?

Blower is the key equipment in electric power, petrochemical, metallurgical, mechanical and other sectors. Once the failure occurs, it will cause huge personnel and economic losses. For the fan fault diagnosis, because the fan fault forms are various, and the causes and mechanisms of the fault are complex and changeable, the development of the fan field diagnosis research is not mature enough.
Therefore, for the blower, the balancing measures of the blower are necessary, because it can reduce the blower failure, avoid accidents or casualties caused by the blower failure.
For blowers, the purpose of balancing blowers is to reduce vibration, noise, stress in operation, increase bearing life, reduce interference and fatigue to operators, and reduce energy loss.
