3、53893706摘 要 限压式变量叶片泵作为液压元件之一，在实际生产中得到广泛的应用。限压式变量叶片泵能按负载大小自动调节流量，功率利用合理，可减少油液发热，故常用于执行元件有快慢速要求或有保压要求的场合。快速时负载小，压力低。慢速进给时，负载大，压力高，流量小，泵自动转换到特性曲线段。保压时，在近点工作，提供小流量以补偿系统泄漏这种限压式变量叶片泵的额定压力为6.3pa，从另外一方面来说，叶片泵作为液压系统的动力源，对液压系统的好坏起绝对的作用，有着巨大的影响。因此，限压式变量泵性能测试的工作台的建设很重要；本文重点讲述了限压式变量叶片泵的分类，工作原理以及在实际当中的应用，对限压式变量叶片
