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。
The shafting throw of vertical pumping units is main characteristics data that reflect the lateral vibration of water pumping units. The lumped parameter model of shafting of vertical pumping units is established based on on-site measurement throw data of pumping units. By using geometry decomposition and calculation methods, the deformation shapes of water pump shaft section and electromotor shaft section are defined respectively and then four basic shapes of shafting throw are defined. Based on the measurement data of No. 1 pumping unit in Niulanjiang-Ganhe Pump Station, the calculation steps and method of shafting throw shape are presented. The results show that the proposed method can visually reflect the deformation of water pump shafting, and provide more valid analysis tool for shafting vibration.
