【摘要】：立轴水泵机组的摆度是反映水泵机组横向振动的主要特征数据。利用泵站水泵机组实测摆度数据,构建立式水泵机组轴系摆度形态参数模型,采用几何分解计算和分析方法,定义水泵转轮段和电动机段的轴系变形形态,进而定义了轴系摆度的4种基本形态。以牛栏江-干河泵站1号水泵摆度测量数据为例,对轴系摆度形态的计算方法给出了详细的计算说明。结果表明,上述轴系形态试验计算方法能直观的反映水泵轴系的变形,为轴系振动分析提供更有效的分析手段。
[Abstract]:The pendulum of vertical shaft pump unit is the main characteristic data reflecting the lateral vibration of pump unit. Based on the measured shimmy data of pump unit in pump station, the shafting shape parameter model of vertical pump unit is constructed, and the shafting deformation pattern of pump runner and motor section is defined by geometric decomposition calculation and analysis method. Furthermore, four basic forms of shafting pendulum are defined. Taking the measured data of No. 1 pump of Niulanjiang Ganhe pumping Station as an example, the calculation method of shafting pendulum shape is given in detail. The results show that the above methods can reflect the deformation of water pump shafting directly and provide a more effective analysis method for shafting vibration analysis.
