摘要：振动值异常是大型旋转机械常见故障，振动故障诊断对于机组的长期稳定运行尤为重要。本文借助CSI2130振动分析仪对内蒙古国华准格尔发电有限责任公司发生的2起典型辅机振动异常故障进行分析，运用故障诊断技术理论并结合工作经验，确定振动异常的原因分别为泵的出口逆止门不严密及刚度不同而引起的不同共振，对此分别及时采取了更换出口逆止门及对给水泵的润滑油管道加装补偿器的措施，消除了设备隐惠。事实证明，CSI 2130振动分析仪在振动故障诊断分析中效果明显，可为实施状态检修和优化检修提供服务。

Abstract: Abnormal
vibration fault diagnosis is particularly important for long term stable operation. 2 typical abnormal vibration cases in Inner Mongolia Guohua Zhungeer power Generation Co.,Lid. are analysed by CSI 2130, using the application technology of fault diagnosis theory and combined with the working experience, the author successly found out the causes, in which
lax and stiffness difference caused by different
the power consumption rate of outlet was
resonance. Thus the author took timely and appropriate measures of replacing the power consumption rate and adding compensator to eliminate the hidden trouble of equipment. The facts show that CSI2130 vibration analyzer to dealing with fault diagnosis is effective, which can provide services for state maintenance and maintenance optimization.
