摘要
介绍了一起因透平膨胀机转子旋转失速而导致连续多次损坏膨胀叶轮故障的案例。对故障的原因及故障处理过程作了详细的分析与说明,同时,对振动频谱分析方法在旋转设备故障诊断过程中的实践应用作了充分论述。
Rotary stalling of turbo-expander rotor caused many times’ damege of expansion impeller.The fault causes and the fault treatment are analyzed and explained in detail.At the same time,the application of the vibration spectrum analysis method in dignosis of rotary equipment faults are discussed thoroughly.
