美国VICKERS威格士叶片泵45V60A1A22R

美国VICKERS威格士叶片泵45V60A1A22R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。叶片泵转子旋转时，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。

叶片泵的管理要点除需防干转和过载、防吸入空气和吸入真空度过大外，还应注意：

1．泵转向改变，则其吸排方向也改变叶片泵都有规定的转向，不允许反。因为转子叶槽有倾斜，叶片有倒角，叶片底部与排油腔通，配油盘上的节流槽和吸、排口是按既定转向设计。可逆转的叶片泵必须专门设计。

2．叶片泵装配 配油盘与定子用定位销正确定位，叶片、转子、配油盘都不得装反，定子内表面吸入区部分较易磨损，必要时可将其翻转安装，以使原吸入区变为排出区而继续使用。

3．拆装 注意工作表面清洁，工作时油液应很好过滤。

4. 叶片在叶槽中的间隙太大会使漏泄增加，太小则叶片不能自由伸缩，会导致工作失常。
