Embodiment Construction

[0017] figure 1 Among them, 9 is the front donkey head, 10 is the rear donkey head, 11 is the beam, 12 is the sucker rod, 8 is the steel wire rope, 7 is the connector, 6 is the bracket, 5 is the Christmas tree, R is the rotation radius of the front donkey head, R=6m, r is the radius of the back donkey head, r=1.2m, β M is the maximum rotation angle, β M =95.5°, Δβ=5.5°. Wherein O point is the supporting point of the beam, obviously the back donkey head pulled by the oil cylinder 13 makes the beam rotate around the vertical plane, so that the front donkey head 9 pulls the sucker rod 12 to move up and down by the wire rope 8 to achieve the oil pumping purpose. But front donkey head 9 will enter support 6 part when reaching bottom dead center. Among them, point O is 12m above the ground.

[0018] Hydraulic system of the present invention sees figure 2 . Among them, 13 is an oil cylinder, 14 (power on), 15 (power off), 19 (power off) is an electromagnetic reversing valve, a...

Abstract

The invention discloses a fourth-generation efficient long-stroke long-life intelligent mechanical electrical and hydraulic oil pumping unit which is composed of a long-stroke framework, an efficienthydraulic system and an optimized electronic control system. The stroke is 10m, the surface efficiency is 72%, and the service life can reach 10 years; the pumping unit can work at + / -40 DEG C withoutheating and cooling; the stroke and the times of stroke are subjected to stepless adjustment and balancing weight-free type precise balance; in addition, the pumping unit is further provided with anoverloaded, load-breaking, liquid level, automatic temperature perception and halt alarm system; moreover, the pumping unit can operate in an optimized oil extraction manner of faster ascending and slower descending and improve the oil extraction efficiency of a downhole pump.

Description

Technical field [0001] The present invention relates to the fourth-generation high-efficiency, long-stroke and long-life intelligent electromechanical-hydraulic pumping unit. and electronic control system. Background technique [0002] Due to lack of good cooling device and short service life of the hydraulic mechanism, low efficiency and short stroke, the present hydraulic pumping units are still unable to meet the needs of the oil field, so there are few users. The invention can make the ground efficiency of the hydraulic pumping unit up to 70-72%, the stroke up to 10m, and the service life up to 10 years, and make the hydraulic pumping unit light in weight, and the stroke and stroke times can be continuously adjusted, and can also be fast up, slow down and Overload, off load can automatically stop and alarm. In addition, the patent of the present invention also provides the optimized complete machine circuit, the concrete structural diagram and the size of the long-stro...
