摘　　要：本文通过对某钢铁公司3#鼓风机1#瓦发生乌金碎裂的原因分析,阐述了碎瓦故障的机理。通过分析提出,汽轮机对轮瓢偏超差和风机转子局部裂纹是导致1#瓦产生乌金碎裂和不稳定的主要原因。针对该机组奇特的振动现象描述了故障征兆,提出了消振措施及其故障排除方法,对类似机组的故障诊断有指导意义。This paper takes the No. 3 Air Blower of Baotou Steel and Iron Company as an example to explain the principle of the bearing pad crashing by analyzing the failure cause of No. 1 bearing Babbit Alloy. The main reason to cause the No. 1 bearing pad crashing and unsteady is turbine coupling running aberrancy and blower rotor local crack. This paper describes the sign of failure aiming at the peculiar vibration of this unit and puts forward the methods of vibration and fault eliminating.
