科里奥利力学原理粉体计量秤补偿技术研究

Compensation technology of Coriolis mechanics powder weigher

依据科里奥利力学原理的粉体质量计量秤都采用三相异步电机作为驱动装置,但其测量盘转速会随负载变化而变化,这必然给计量结果带来偏差。针对这一技术难题,提出了"补偿技术"概念;并简述了补偿技术的必要性,详实描述了补偿技术的研究过程。其中建立的失速补偿数学模型,已经过试验验证并取得了理想的实际应用效果。

Powder weigher based on Coriolis mechanics usually has three-phase asynchronous motor as driving device, but its measur- ing wheel＇s speed will change with load, which inevitably brings deviation to measuring results. Aiming at this technical problem, idea of ＂compensation technology＂was advanced, and the necessity and study process was introduced. The compensation mathematical mod- el has been tested and obtained ideal practical application.
