Abstract

The invention discloses a dual horsehead fine balance energy-saving walking beam pumping unit comprising a waling beam assembly, a bracket assembly, a power assembly and a brake assembly. The middle part of the walking beam assembly is articulated with the upper end of the bracket assembly through a central bearing base; the front and rear ends of the walking beam assembly are respectively connected with a front horsehead and a rear horsehead; the front and rear horseheads are respectively connected with one end of a hauling steel rope; the other end of the hauling steel rope is respectively connected with a reel of the power assembly; the front horsehead is provided with a rope hanger, and the rear horsehead is provided with a balance block; the bracket assembly is provided with a tension mechanism assembly and a buffer mechanism assembly; and the steel rope winds through the tension mechanism assembly and the buffer mechanism assembly to realize tension and buffer. The invention solves the problems of much material consumption of the regular beam-pumping unit and large impact load of a vertical pumping unit, and the like, has reasonable design, realizes remote control, monitors the parameter variation of the pumping unit at any time and ensures favorable social and economic benefits.

Description

Technical field [0001] The invention relates to an oil pumping unit, in particular to a double donkey head fine balance beam pumping unit. Background technique [0002] In the process of oil extraction in the oil field, the pumping unit is one of the main oil extraction equipment in the oil extraction operation. The existing beam pumping unit has a large body, a lot of consumables, and a large energy consumption. Although the vertical pumping unit occupies a small area, it is energy-saving from the surface phenomenon; but the impact load is large, and the damage to the sucker rod and the sucker pump is large. During the movement, it moves at a uniform speed. The load cannot be uniformly changed during the working cycle of the oil well pump. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a double donkey head fine balance beam pumping unit with reasonable design, simple and ...
