Straight-line balance type long stroke energy-saving oil pumping machine

The utility model discloses a linear balance energy-saving oil pumping unit, which is a novel energy-saving oil pumping unit which adopts a scale-typed balanced principle to implement a balance, adopts a high frame supporting to implement a long stroke and adopts the driving of a switch electromagnetic resistance motor (a switch electromagnetic resistance speed adjusting steering motor) to implement the reciprocating motion of an oil pumping rod so as to reach an aim of oil extraction. The utility model mainly consists of a base, a main frame (a high frame), an upper platform (an upper driving platform), a power driving component arranged on the upper platform, a counterweight box and an electric control cabinet. The utility model is mainly characterized in that the lower part of the oil pumping machine is fixed on a ground foundation; the upper end of the main frame is connected with the upper driving platform; under the control of the electric control cabinet, the driving system drives the oil pumping rod and a balance box to reciprocate up and down in order to implement the oil extraction from an oil well. The utility model has the advantages of implementing long stroke, energy-saving, high efficiency and durability.
