PU2R1-19-L-R 变量叶片泵直销

变量叶片泵直销PU2R1-19-L-R叶片泵，是转子槽内的叶片与泵壳(定子环)相接触，将吸入的液体由进油侧压向排油侧的泵。

因为历史的叶片泵根据中类型的不同有两种

一）专门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）或其他特殊的泵。

这类泵产品一般不会叫叶片泵。但作为专著，叶片泵几乎全部是指离心泵、混流泵、轴流泵等(一级建造师2014《机电工程与管理实务》中称这三类为叶轮泵)。

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。

变量叶片泵工作原理编辑

变量叶片泵的定子内表面是一个圆形，转子与定子间有偏心距，在配油盘上只开有一个吸油窗口和一个压油窗口。当转子在电动机驱动下按图示箭头方向旋转时，叶片经定子下半部时，在离心力的作用下，从叶片槽中伸出，两叶片间的密封容积增大，实现吸油；叶片经定子上半部时，被定子内表面逐渐压入叶片槽内，密封容积减少，实现压油。泵的转子每转一转，每个密封容积吸、压油各一次。改变定子和转子间的偏心量，便可改变泵的排量，故称为变量叶片泵。
