Abstract

An oil pumping unit is characterized in that it includes a frame, and guide slides are arranged on both sides of the frame, and the directional slide with guide wheels cooperates with the guide slides, and the frame is provided with two There are two pulleys, the upper and lower ends of the directional slide plate are respectively connected with steel cables, the upper end of the steel cable contacts the two pulleys and is connected with the counterweight, and the lower end of the steel cable is connected with the sucker rod to form a reciprocating lifting and pumping mechanism; on the frame There is a driving shaft connected with the electric reducer, sprockets are respectively fixed at both ends of the driving shaft, and the two sprockets are respectively connected to the double sprocket through the chain, and the two double sprockets are respectively connected to the double sprocket through the chain. In addition, the sprockets are connected, and the two chains are fixed with a bridge shaft, and the pulley matched with the notch of the directional slide plate is mounted on the bridge shaft to form a driving device. It has the advantages of long sucker rod stroke, high oil pumping rate, compact structure, small size, light weight, energy saving, low manufacturing and operating costs, etc. This machine can also be used for pumping water, or as a power source for other machinery.

Description

Technical field [0001] The invention relates to an oil pumping unit related to an oil extraction operation machine. Background technique [0002] The existing pumping unit for oil production is mainly composed of a crank, a connecting rod, a walking beam, a donkey head, and a steel cable driven by a motor and a reducer. Its shortcomings are that the whole machine is large and heavy, consumes a lot of steel, the reciprocating stroke of the sucker rod is small, the pumping efficiency is low, and the manufacturing and operating costs are high. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an oil pumping system that can enlarge the stroke, long sucker rod stroke, high pumping efficiency, compact structure, small volume, light weight, saving steel, energy saving, and low manufacturing and operating costs. machine. This pumping unit can also be used for pumping water; or as a ...
