振动异常,vibration anomaly
1)vibration anomaly振动异常
1.By studying vibration trends,waveform frequency spectrum,axis trajectory map,down load and vibration the diagram,as well as oil temperature,oil pressure and vibration the diagram,it is found that the device main air compressor motorvibration anomaly is due to lower oil temperature,oil pressure caused by the changes,which led to the oil whip.兰州石化公司300万t/年重油催化裂化装置主风机组电机振动突然由50多μm增加到100μm,甚至有时达到160μm,而且有较大的波动,通过研究、分析振动趋势图、波形频谱图、轴心轨迹图、降负荷与振动的关系图以及油温、油压与振动的关系图,发现该装置主风机组电机振动异常的原因是由于油温的降低引起油压的变化,进而引起了油膜振荡。

点振子振动和点电极振子振动分子式：CAS号：性质：又称点振子振动和点电极振子振动。振动能量绝大部分集中在点电极范围内，形成“能量封闭”的振动模式。振子电极面远小于压电陶瓷片的总面积，且与厚度有适宜的匹配关系。在交变电场作用下，沿厚度方向产生振动，其振幅随着至电极中心距离的增加，呈指数式衰减。谐振频率与压电陶瓷片的厚度有关。为提高频率通常将压电陶瓷片磨得很薄，有时考虑到压电陶瓷自身强度太低，可用特制的陶瓷片作垫片来防止压电陶瓷片损坏。常用于高频场合。
