| 摘 要： | 透平膨胀机是低温法空分设备及气体分离和液化装置中的重要部机之一,在实际生产中,膨胀机处于高速运转中,最常见也是最易发生的故障大多是由转子—轴承系统振动所引起。分析叶轮轴向窜动、转子不平衡振动、轴承自激振动、喘振和液击现象等振动故障的原因,提出改进措施,以保证空分设备稳定和安全运行。

| Abstract: | The turbine expander is one of important devices of the low-temperature process air separation plant and the gas separation and liquefaction equipment. During actual production,the expander runs at high speed,and thus the most common and most liable trouble is usually resulted from vibration of rotor-bearing system. The causes for axial displacement of impeller,unbalanced vibration of rotor,self-excited vibration of bearing,surge,and liquid hammer are analyzed,and for safe and steady run of air separation plant the improving measures are proposed. |
