油膜涡动 meaning in English
oil whirl
Examples
- The vibration signals analytical result of rotating machinery mass imbalance and oil film turbulence fault verified its feasibility and validity
旋转机械质量不平衡和油膜涡动故障的振动信号分析结果进一步验证了这种方法的可行性和有效性。 - A new phenomenon is found numerically and experimentally : even if the rotating speed of the rotor is lower , the subharmonic vibration of the rotor - bearing system may be occurred under great disturbance ( unbalance )
通过理论计算和分析发现：提出了即使在较低转速的情况下，只要外激励(不平衡量)足够大，也有可能导致转子出现油膜涡动或者失稳的现象。 - This thesis measured the vibration signals of 1 # and 2 # running turbine - generator sets in a generating plant and their vibration signals that are indispensable to the study are gained . firstly , the low frequency faults of machine stand in generator side , rotor unbalance , misalignment , oil whirl , oil whip are diagnosed by fft analysis . secondly , applying wavelet theory to probing the instantaneous abnormal phenomena of the signals and to show their components
首先应用fft分析诊断出1 #和2 #汽轮发电机组存在的发电机侧机座松动、转子失衡、不对中、油膜涡动、油膜振荡等故障，再运用小波分析探测信号中的瞬态反常现象并展示其成分，比较精确地诊断出了该发电厂运行中的1 #和2 #汽轮发电机组存在的碰摩故障。
