Problems solved by technology

No matter what kind of driving method the screw pump adopts, it does not match the power driving method of the currently used pumping unit, which means that countless pumping units will be scrapped, resulting in an increase in the investment cost of the enterprise, increasing the cost and wasting resource

Abstract

A straight driving reciprocal rotary screw pump comprises a rotor, a stator, a pump base under the rotor, a fuel inlet valve (1) and a fuel outlet valve (2) on the pump base, and an universal coupler, a connecting axle (1), a connecting axle, (2), a screw couple, and a spline couple which are distributed from up to down. The universal coupler is connected with the upper end of the rotor, the universal couple is arranged with the pump base around, the pump base is disposed with the valve (2) and the valve (1), the screw couple comprises a screw axle, a screw muffle, a rotation ball block, and a ball, and the spline couple comprises a spline axle, a spline muffle, a ball block, and a spline ball. The invention has high producing efficiency and wide application.

Description

technical field [0001] The invention relates to the power driving mode and the structure of the pump body of the screw pump when the screw pump is used in oil field production. Background technique [0002] The screw pump is a new type of internal meshing rotary positive displacement pump, which has the advantages of high efficiency, strong self-priming ability, and wide application range, and has been widely used in oil fields. As the core equipment in oilfield production, the pumping unit has many "three-pumping" pumping wells at home and abroad, including beam pumping units, beamless pumping units, and friction lift pumping units. Pumps and linear motor-driven pumping units, etc., are all driven by the pumping unit to make up and down reciprocating linear motions of the sucker rod, thereby driving the rod plunger pump to work. With the continuous development of major oilfields in my country, the difficulty of oilfield development is increasing, and heavy oil with high sa...
