三维轴心轨迹法在输油泵机组状态评价中的应用

The Application of State Evaluation of Pump Set Based on Three-dimensional Axle Centre Trail

定性分析了输油泵机组转子在不同状态下轴心轨迹的运行状况,提出了融合相位及轴心轨迹半径两个指标的多测点、三维轴心轨迹法,从整机角度对输油泵机组进行了整体评价,并定量提取了多个评价指标。通过现场检测试验证明了该状态评价方法的有效性,并分析了运行变化趋势。

Based on the axle centre trails in different operation situation of oil pumps, and a method of the multi-measuring point and three-dimensional axle centre trails which syncretized two indexes information, axle centre trail radius and phase,are refined. This method can be used to evaluate the unit in unitary. Some evaluation indexes are refined quantitatively. At last, the evaluation method usability is proved in further through some field examination examples,and analyzes the operation change tendency as well.
