The invention relates to a torque-balance beam pumping unit comprising a base, a support, a walking beam, a crossbeam, a connecting rod, a crank, a speed reducer, a motor, a beam hanger and the like. The torque-balance beam pumping unit is characterized in that the back part of the base is provided with a balance rod support, the upper part of the balance rod support is provided with a support shaft, one end of a balance rod is articulated with the support shaft, the other end of the balance rod is provided with a balance block, and a groove is arranged on the balance rod. The lower part of the connecting rod is provided with a roller wheel mechanism, and a roller wheel on the roller wheel mechanism is arranged in the groove on the balance rod; the force arm of the roller wheel, on the right side of an output shaft of the speed reducer, is lengthened during a down stroke, and the balance rod and the balance block are uplifted by using smaller force; the force arm of the roller wheel, on the left side of the output shaft of the speed reducer, is shortened during an upstroke, the balance gravities of the uplifted balance rod and the uplifted balance block, acting on the roller wheel, are increased to reduce a torque, therefore, the torque-balance beam pumping unit achieves an obvious energy-saving effect.
Description
1. Technical field [0001] The invention relates to a pumping unit, in particular to a beam pumping unit with variable torque balance. 2. Background technology [0002] At present, most of the pumping units used in mechanical oil recovery in oilfields are conventional beam pumping units with a balance block on the crank. The advantages of this type of pumping unit are solid, durable and reliable, but the disadvantages are large torque and large energy consumption. In recent years, there have been many models with improved balance methods, such as diameter-adjusting and variable-torque beam pumping units, downward-biased barbell beam pumping units, etc., which have a certain energy-saving effect, but the energy-saving range is not large, and the effect is not good. Very ideal. 3. Contents of the invention: [0003] Purpose of the invention: In order to overcome the disadvantages of large torque and high energy consumption of the conventional beam pumping unit with a balance...
