摘要： A multi-stage vane-type positive displacement pump used for lifting fluid from oil wells has stages disposed on a common shaft. Each stage has a rotor, a stator, separating vanes, working chambers, a lower cap with inlet ports, and an upper cap with outlet ports. The rotor is in the form of a cam. The stator is formed from two concentric sleeves situated on a base and having an annular gap therebetween. Slots are provided in the inner sleeve and in the base for the movement of the vanes. The vanes are connected to one another by a synchronizing element. The ports are situated opposite the chambers, either side of the vanes. The end faces of the caps of adjacent stages are conjoined to form an annular cavity, which communicates with the gap of the preceding stage. The aim is to increase the reliability of the pump, to simplify the design and to reduce the manufacturing cost thereof while enabling the pumping of fluids with a high content of abrasive particles.
摘要翻译：用于从油井提升流体的多级叶片型容积式泵具有设置在公共轴上的阶段。每级具有转子，定子，分离叶片，工作室，具有入口端口的下盖和带出口的上盖。转子是凸轮的形式。定子由位于基座上的两个同心的套管形成，并在其间具有环形间隙。插槽设置在内套筒和底座中用于叶片的运动。叶片通过同步元件相互连接。这些端口位于与叶片相对的两侧。相邻级的盖的端面被结合形成环形腔，其与前一级的间隙连通。目的是提高泵的可靠性，简化设计并降低其制造成本，同时能够泵送具有高含量磨料颗粒的流体。
