Problems solved by technology

[0003] However, in the above scheme, the piston of the reciprocating pump hits the valve core to switch the direction of movement of the liquid, thereby realizing the reciprocating motion of the piston; in this process, the valve core directly transmits the impact force of the piston to the pump body, and due to The reciprocating motion of the piston is relatively fast, so there are impacts from two different directions on the pump body, which is easy to cause the natural vibration (resonance) of the pump body, which will cause a crash and cause the entire system to fail to work

Embodiment Construction

[0051] The present invention will be further described below in conjunction with specific examples.

[0052] Such as Figure 1 to Figure 9 As shown, the hydraulic double-acting rodless oil recovery pump in this embodiment includes a cylindrical pump body 1 and supporting pipelines axially arranged in the pump body. Composed of tailstock 4;

[0053] The supporting pipeline includes an uplink signal pipeline 51, a downlink signal pipeline 52, a liquid inlet pipeline 53, a liquid return pipeline 54 and an oil pump pipeline 55, and a main pipeline 58 is arranged at the center of the functional section. All other pipelines are arranged around the main pipeline, that is, each pipeline is set at a phase angle of 60 degrees with the main pipeline as the axis; figure 1 As shown, the uplink signal pipeline 51 and the downlink signal pipeline 52 are arranged symmetrically on both sides of the main pipeline; after being separated by a phase angle of 60 degrees, the liquid inlet pipeline...

Abstract

The invention discloses a hydraulic double-acting rodless oil extracting pump and a system, and aims at solving the problem that natural oscillation is easily generated in the prior art. Through additional arrangement of a signal valve component in a main pipeline, the possibility that piston collision is transferred to a pump body is decreased, thus the problem of natural oscillation is overcome.

Description

technical field [0001] The invention relates to a hydraulic double-acting rodless oil recovery pump. Background technique [0002] In order to overcome major mechanical accidents such as eccentric wear and rod drop that are easy to occur when the existing equipment is pumping heavy oil; Chinese Patent No. ZL200820110494.9 discloses a hydraulic double-acting rodless oil production pump. This kind of rodless oil production pump uses the ground power pump to transfer the pressurized hydraulic flow down the power fluid pipe to the liquid inlet pipeline of the hydraulic double-acting rodless oil production pump. It is converted into mechanical energy and reciprocates up and down to make the reciprocating pump reciprocate, so that the pump chamber drives the crude oil pipeline to achieve oil suction and lifting. This kind of rodless oil production pump has no pump rod, can adapt to highly inclined wells and horizontal wells, and can prevent major mechanical accidents such as ecce...
