【摘要】：针对现有磁性液体视密度测量装置在实际测量过程中的繁琐及实验误差较大的弊端,设计了一台磁性液体悬浮性能测试智能装置,并以此通过计算机界面在线显示磁性液体悬浮性能的测试过程和规律曲线。结果表明,悬浮性能与磁场强弱、磁场梯度大小相关,磁场越强,梯度越大的液层,磁性液体悬浮性能越强。智能装置使纳米磁性液体悬浮性能的整个测试过程和测试方法更加简单直观,整体实验误差较小。通过对其影响因素所进行的理论分析,可为磁性液体在矿山选矿、物质分离等方面的潜在应用提供理论基础。
[Abstract]:In view of the disadvantages of the existing magnetic liquid apparent density measurement device in the actual measurement process and large experimental error, a magnetic liquid suspension performance test intelligent device is designed. The test process and regular curve of magnetic liquid suspension performance are displayed online by computer interface. The results show that the suspension property is related to the magnetic field and the magnetic field gradient. The stronger the magnetic field is, the stronger the magnetic liquid suspension performance is. The intelligent device makes the whole testing process and testing method of the suspension performance of nanometer magnetic liquid more simple and intuitive, and the overall experimental error is smaller. The theoretical analysis of the influencing factors can provide a theoretical basis for the potential application of magnetic fluids in mineral dressing and material separation in mines.
