齿轮泵工作原理

液压泵是靠密封容腔容积的变化来工作的.原动机带动泵旋转时,通过一定机构使泵内的密封工作腔的容积发生变化,由配流装置使密封工作容积轮流和吸油口或压油口相通,从而使泵进行吸油和排油.

密封容积大→泵吸油 输入: 转矩和转速

密封容变小→泵压油 输出: 压力和流量

基于.上述工作原理的液压泵叫做容积式液压泵,液压传动中用到的都是容积式液压泵。

液压系统的组成及其作用
一个完整的液压系统由五个部分组成,即动力元件、执行元件、控制元件、辅助元件(附件)和液压油。
动力元件的作用是将原动机的机械能转换成液体的压力能,指液压系统中的油泵,它向整个液压系统提供动力。液压泵的结构形式一般有齿轮泵、叶片泵和柱塞泵。
