Zusammenfassung: | The invention discloses a rapid determination method for a non-typical power frequency fault of a rotor-elliptic tile bearing. An axis location graph is used as a main analysis frequency spectrum; calculation is carried out to obtain a location changing value of the center of a shaft neck in an elliptic tile bearing; and thus unstability of a rotor-elliptic tile bearing is deduced to be a main factor causing a vibration fault rapidly. Therefore, the blindness and arbitrariness of vibration fault diagnosis and treatment are avoided, the troubleshooting time of the set is shortened substantially, the number of times of fault treatment is reduced, the maintenance cost of the enterprise is saved, and a phenomenon that immeasurable economic losses are caused to the clients due to the long repairing time or incomprehensive repairing is avoided.
本发明公开了种转子-椭圆瓦轴承非典型工频故障的快速判别方法,利用轴心位置图作为主要分析频谱,通过计算得出轴颈中心在椭圆瓦轴承中的位置变化量的大小,可快速推导出转子-椭圆瓦轴承失稳是引起振动故障的主因;避免振动故障诊断与处理的盲目性和随意性,大大缩短机组故障排查时间,减少了故障处理次数,节约了企业的检修成本,避免因检修时间过长或检修不彻底,给客户 |
