Rotary positive displacement hydraulic device and hydraulic driving type petroleum production oil pump

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.

Description

1. Technical field: [0001] The invention relates to a rotary volumetric hydraulic device, in particular to a working chamber volume change formed by a matching component in a uniformly distributed groove on the outer circumference of the rotor during the rotor's rotary process to form a volume change in the working chamber to complete the work, including a hydraulic pump, a hydraulic motor, A hydraulic device including a hydraulic transmission also relates to a hydraulic transmission oil extraction pumping unit closely related to the device. 2. Background technology: [0002] The closest background technology with the present invention is: my application number is 02143041.1, the publication number is CN1415860A, and the publication date is May 7th, 2003, and the name is called "rotary volume type hydraulic transmission device and hydraulic transmission oil extraction pumping unit" The technical solution proposed in the invention patent application. This background technica...

AI Technical Summary

Problems solved by technology

[0003] Compared with the corresponding products currently in use, hydraulic pumps, hydraulic motors, and hydraulic actuators constructed according to the background technology have obvious advantages in terms of comprehensive economic effects, but the difficulty in realizing the manufacturing process of the products is still relatively high. The working reliability and working life of finished products are still relatively low

Compared with the existing pumping units in use, the hydraulic transmission oil extraction pumping unit constructed according to the background technology has the advantages of simple structure, low manufacturing and use costs, and energy saving. In addition, the composition of the stroke and stroke control system is slightly complicated, and the working reliability is also insufficient.
