The invention provides a self-adjusting consumption-reducing energy-saving device of a pumping unit, and relates to the technical field of oil field pumping units. The self-adjusting consumption-reducing energy-saving device comprises a back-crank pumping unit composed of a base, a main motor, a speed reducer, a crank, a balance block, a connecting rod, a walking beam, a horse head, a beam hanger, a support, a support shaft and a control cabinet; the middle of the support is connected with the middle of a balance beam through a middle shaft, a roller is arranged at the right side of the balance beam and abuts against the lower end face of the walking beam, and a balance device is installed at the left side of the balance beam. The self-adjusting consumption-reducing energy-saving device has the following beneficial effects that the distance between the roller of the balance beam and the support shaft changes in a reciprocating manner to change the arm of force of reverse balance torque, a torque sensor measur
