| description | The utility model discloses a hydraulic energy storage balancing long-stroke pumping unit which comprises a winch assembly, a hydraulic energy storage balancing device, a fixed pulley, a steel wire rope, a pumping rod, a first coupler, a base, a winch assembly seat and a fixed pulley frame. The winch assembly comprises a motor, a speed reducer and a roller. The hydraulic energy storage balancing device comprises a transmission device, a second coupler, a gear rack mechanism, a plunger type cylinder and a hydraulic energy accumulator. The winch assembly providing power drive is arranged on the base, long stroke can be achieved without depending on a high tower, only a longer steel wire rope needs to be wound on the roller, stability and reliability are improved, and maintenance is facilitated. A hydraulic energy storage balancing device is adopted, and gravitational potential energy released by a sucker rod is converted into hydraulic energy in a hydraulic energy accumulator to be stored during down stroke; an |
