摘要

珠江电厂4×300MW机组运行中多次出现引风机振动大导致叶片断裂事故

严重影响了电厂的安全经济运行。分析认为系统阻力过大、叶片材料质量差、动不平衡、扩散器振动等是造成引风机振动大甚至叶片断裂的主要原因。对此

采取了相应的治理措施

从根本上解决了引风机振动大甚至叶片断裂问题。

Abstract

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.
