变量液压泵的结构区别
1.在变量液压泵中,当叶片处于压油区时,叶片底部通压力油,当叶片处于吸油区时,叶片底部通吸油腔,这样,叶片的**部和底部的液压力基本平衡,这避免了定量液压泵在吸油区定子内表面严重磨损的问题.如果在吸油腔叶片底部仍通压力油,叶片**部会给定子内表面以较大的摩擦力,以致减弱了压力反馈的作用。
2.叶片也有倾角,但倾斜方向正好与定量液压泵相反,这是因为变量液压泵的叶片上下压力是平衡的,叶片在吸油区向外运动主要依靠其旋转时的离心惯性作用.根据力学分析,这样的倾斜方向更有利于叶片在离心惯性作用下向外伸出。
3.变量液压泵结构复杂,轮廓尺寸大,相对运动的机件多,泄漏较大,轴上承受不平衡的径向液压力,噪声较大,容积效率和机械效率都没有定量液压泵高;但是,它能按负载压力自动调节流量,在功率使用上较为合理,可减少油液发热。

液压泵因为历史的液压泵根据中类型的不同有两种
一）指容积泵中的滑片泵。
二）指动力式泵的三泵（离心泵、混流泵、轴流泵）或其他的泵。
这类泵产品一般不会叫液压泵。但作为专著，液压泵几乎全部是指离心泵、混流泵、轴流泵等。
根据其每转的理论排量是固定值还是可变值，可以分为叶片式变量泵和叶片式定量泵。
工作原理编辑液压泵转子旋转时，叶片在离心力和压力油的作用下，尖部紧贴在定子内表面上。这样两个叶片与转子和定子内表面所构成的工作容积，先由小到大吸油后再由大到小排油，叶片旋转一周时，完成两次吸油与排油。
