关于可倾瓦轴承油膜涡动和油膜振荡的实例与探讨

Examples and Discussions on Oil Film Whirl and Oil Film Oscillation of Tilting Pad Bearings

离心压缩机长期安全稳定运行直接关系到企业的生产效率和效益,而保证离心压缩机安全稳定运行的其中一项关键指标就是振动。通过监测振动值,可知设备运行是否正常。当振动发生异常时,对振动故障的有效的诊断和处理就显得尤为重要。油膜涡动和油膜振荡是较为严重的离心压缩机振动故障,一般多发于圆瓦轴承和椭圆瓦轴承。文章结合一例实际案例,针对可倾瓦轴承油膜涡动和油膜振荡故障进行了相关分享与探讨。

The long-term safe and stable operation of centrifugal compressors is directly related to the production efficiency and efficiency of enterprises,and one of the key indicators to ensure the safe and stable operation of centrifugal compressors is vibration.By monitoring the vibration value,it can be determined whether the equipment is operating normally.When the vibration is abnormal,effective diagnosis and treatment of vibration faults are particularly important.Oil film vortex and oil film oscillation are more serious vibration faults of centrifugal compressors,usually occurring in round and oval pad bearings.This article combines an actual case to share and explore the relevant issues of oil film vortex and oil film oscillation faults of tilting pad bearings.
