武汉翔升达机电长期备有原装力士乐PV7系列叶片泵:
叶片泵分为双作用泵和单作用泵:
双作用泵工作原理:它由定子、转子、叶片和配油盘等组成。定子内壁近似椭圆形。叶片安装在转子径向槽内并可沿槽滑动,转子与定子同心安装。当转子转动时,叶片在离心力的作用下压向定子内表面,并随定子内表面曲线的变化而被迫在转子槽内往复滑动,相邻两叶片间的密封工作腔就发生增大和缩小的变化。叶片由小半径圆弧向大半径圆弧处滑移时,密封工作腔随之逐渐增大形成局部真空,于是油箱中油液通过配油盘上吸油腔吸入;反之将油压出。转子每转一周,叶片在槽内往复滑移2次,完成2次吸油和2次压油,并且油压所产生的径向力是平衡的,故称双作用式,也称平衡式。
单作用式叶片泵工作原理:主要由定子、转子、叶片和配油盘等组成。定子的内表面是一个圆柱形,转子偏心安装在定子中,即有一个偏心距e,叶片装在转子径向滑槽中,并可在槽内径向滑动。转子转动时,在离心力和叶片根部压力油的作用下,叶片紧贴在定子内表面上,这样相邻两片叶片间就形成了密封工作腔。在其中一边,叶片逐渐伸出,密封工作腔逐渐增大,形成局部真空,形成吸油;反之,另一边,形成压油。转子每转一周,叶片在滑槽内往复滑移1次,完成1次吸油1次压油。油压所产生的径向力是不平衡的,故称单作用式,也称不平衡式叶片泵。
