Abstract

A kind of cornering positive displacement hydraulic unit that includes the hydraulic pump,the electrical motor, the driver and its fluid drive is the movement of a kind of double acting fluid drive oil production beam pumping unit. The basic configuration of the hydraulic unit is near to the paddle pump and the electrical motor, the fan component of the paddle pump and the electrical motor are replaced with a kind of bearing segment component, and it has the float side panel and the confess liquid static pressure bush bearing structure, and drives the rotator running through the bearing segment radial moving to and for in the cannel of the rotator and presses the treatment fluid or the pressure liquid, its structure is simple and failsafe. This beam pumping unit fulfills the conversation, the adjustment and the command of the driving stroke through the coordinated control system of the field chopper,the liquid, the electricity, the driving stroke can continually adjusted greatly, and its structure is simple, the cost is low,the range of use is extent.
