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 tensionmechanism 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

1. Technical field: [0001] The invention relates to an oil pumping unit, in particular to a finely balanced energy-saving beam pumping unit with double donkey heads. 2. Background technology: [0002] In the process of oil recovery in an oil field, the pumping unit is one of the main oil extraction equipment in the oil extraction operation. The existing beam pumping unit is large in size, has many consumables, and consumes a lot of energy. Although the vertical pumping unit occupies a small area, it is energy-saving on the surface; however, the impact load is relatively large, and the damage to the sucker rod and the pump is relatively large. The load of the oil well pump cannot be changed uniformly during the oil pumping cycle. 3. Contents of the invention: [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a double-donkey head precision balanced energy-saving beam pumping system with reason...
