摘要:

介绍了一种定量分装秤。在现场应用的基础上，通过实际数据分析研究了产生分装误差的原因。研究发现分装误差由测量误差和出料控制误差2部分构成。研究表明：通过合理设置A/D7730的工作方式，兼顾量化误差和测量滞后误差，可使两误差值之和最小；对分装秤采取减震措施，改进推进螺旋使其回转半径向出口方向逐渐减小，使空中量稳定，并用隔离变压器给控制装置供电，进而抑制高次谐波的干扰，这些措施是提高分装精度的有效手段。

Abstract:

A kind of loading scale was introduced. The causes loading error were analyzed using data of field application. It was founded that the loading error is composed of measurement error and control error. It was concluded that the effective measures to improve loading precision are 1) setting work ways of A/D7730 reasonably, which considers the quantization error and measurement lag error can reduce the sum of the two errors to the minimum value; 2) using shock absorption measures; 3) reducing the radius of pushing spiral to the exit gradually to keep stability of the volume in the air; 4) supplying power to controlling device by using the isolated transformer to restrain the interference of high harmonics waves.

Key words: loading error loading precision quantitative error flour loading
