The blades of induced draf fans for 4×300 MW units in Zhujiang Power Plant had large vibration in operation and had been broken for many times
seriously affecting safe and economic operation of the plant.It is believed from analysis that the main causes resulting in large vibration and even blades' breakage are as follows:overlarge resisitance in the system
bad material quality of the blades
dynamic unbalancing
and vibration of the diffuser etc..For these
corresponding remedial measures have been taken
the problem of large vibration and blades' breakage of the induced draft fans being thoroughly soved.
