摘要
采用ADRE for Windows数据采集和处理系统对某300MW火电机组二次风机振动频谱及相位数据进行采集,在此基础上对振动故障进行诊断,通过动平衡试验确定了振动故障的特征为共振,提出了增强设备连接刚度的消振措施,实施后风机运行恢复正常,取得了良好的效果。
A model ADRE for Windows data acquisition and processing system is used to collect the vibration frequency spectrums and phase data in 300MW thermal power unit secondary air fan, diagnosis is carried out to the vibration on this basis, according to the dynamic balance testing to make sure the character of vibration is vibration resonance, taking measure to strengthen the connection stiffness of equipment to remove vibration, fan is running back to normal after repairing and achieved good results.
