Problems solved by technology

[0003] The present invention provides a power balance digital automatic control oil pumping method and an oil production robot, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problems of existing beam beams The pumping unit cannot automatically adjust the balance and the stroke times, resulting in a low balance rate and a mismatch between the stroke times and the oil production of the oil well, resulting in the problems that the pumping unit is prone to failure, it is difficult to achieve the maximum production capacity of the oil well, and the production cost is high.

Abstract

A method for power-balanced, digitized, automatically-controlled oil pumping, and an oil-pumping robot comprising a main engine (15), a decelerator (8), a crank (9), a connecting rod (6), a walking beam (3), a balance arm (7), a derrick (5), a counterweight (2), a base (12), brake equipment (13), a wireline (1), a load sensor (17), a stroke measurer, a safety stop device, and a digital control box (14). Also disclosed is an oil-pumping robot. The present method is safe and reliable and allows for pump self-optimized adjustment of balance and stroke, thus optimizing oil well production, enhancing pump system efficiency, allowing seamless integration with oilfield computer networks, remote data delivery and remote control, simplified operation, convenience, economies of manpower and energy, and greater economic efficiency.

Description

technical field [0001] The invention relates to the technical field of beam pumping units, and relates to a power balance digital automatic control oil pumping method and an oil extraction robot. Background technique [0002] The existing beam pumping units mainly include: conventional beam pumping unit, front beam pumping unit, offset beam pumping unit and special-shaped beam pumping unit, etc. The beam pumping unit generally includes a donkey head, a beam, a bracket, a connecting rod, a base, a crank, a balance device, a reducer, a brake, a motor and a rope hanger, and a bracket, a reducer, a brake, Motor and control cabinet, etc., the beam is hinged on the bracket, the crank is fixed on the output shaft of the reducer, one end of the connecting rod is hinged on the crank, and the other end of the connecting rod is hinged on the beam, thus forming a four-bar linkage Mechanism, the donkey head is installed on the front end of the beam, the rope hanger is installed on the d...
