3． 故障处理建议及非常规处理 根据上述诊断分析得出：（1）不平衡故障是引起低压转子轴振动超标的主要原因，须进行高速动平衡；（2）高增齿轮副及轴瓦磨损，需更换；（3）高增齿轮磨损及轴颈磨损可能导致不平衡，高压转子本身也可能存在不平衡，是高压转子首端轴振动偏高的
3. Troubleshooting suggestions and unconventional treatment According to the above diagnosis and analysis: (1) unbalanced failure is caused by low-voltage rotor shaft vibration exceeded the main reason for the need to carry out high-speed dynamic balance; (2) increased by gear and bearing wear, to be replaced ; (3) High-rise gear wear and journal wear may lead to imbalance, high-pressure rotor itself may also be imbalanced, high-pressure rotor shaft vibration is high
