双作用变量叶片泵的数字化研究

Abstract This article introduced a digital double acting variable vane pump which applies stepper motor as electromechanicalconversion device and single chip as controller. On the basis of the analysis on its structure and operational principle we established amathematical model of variable mechanism and analyzed the relation between output flow and regulation parameters in the variable process.This article comes to a conclusion that the digitization improvement of double acting variable vane pump is feasible.院双作用式变量叶片泵 数字式 工作原理 数学模型 调节参数Key words double acting variable vane pump digital operating principles mathematical model regulation parameters中图分类号院TH31 文献标识码院A 文章编号院1006-4311（2014）01-0064-030 引言随着我国工业现代化建设的快速发展，能源短缺日益严重，合理的利用能源变得更加重要。在流体传动及控制技术领域，节能技术同样必不可少。开展流体传动节能技术的研究不仅可从现有液压设备的节能技术改造中获得巨大经济效益，而且也是我国在先进制造业上赶超国际先进水平的需要1。在工业生产中变量泵是实现液压系统高效 节能的基础，因此研发性能优良的变量泵是流体传动节能技术研究的重要课题之一。
