Vibration Fault Diagnosis and Dynamic Balancing Test for the Induced Draft Fan Motor of a 300 MW Unit
In response to the vibration fault of the induced draft fan motor in a 300 MW unit,a comprehen-sive vibration test and analysis were conducted on both the motor and the induced draft fan,and the causes were clearly identified.By adding weight to the motor fan and the coupling between the motor and the in-duced draft fan,the motor vibration fault was eliminated,satisfying the need of safe and stable operation of the equipment.Meanwhile,the influence coefficients obtained from adding weights on two surfaces can pro-vide experience for similar rotor dynamic balance tests.
