Conventional beam pumping unit

The beam pumping unit is a deformed four link mechanism, with a structural feature similar to a balance, where one end is the pumping load and the other end is the balanced heavy load. For the bracket, if the torque formed by the pumping load and the balanced load is equal or changes uniformly, then the pumping unit can work continuously with a small amount of power.

Foldable irregular beam pumping unit

The special-shaped beam pumping unit series includes models such as double donkey head pumping units, curved beam pumping units, and energy-saving retrofits for conventional beam pumping units.

The special-shaped beam pumping unit is a new model developed based on the conventional pumping unit. It adopts a variable diameter circular arc shaped beam rear arm, and a flexible component connection structure is used between the beam and the crossbeam. The main structure has the characteristics of simple, reliable, and durable conventional beam pumping units. It is easy to achieve long strokes in performance and has outstanding energy-saving characteristics.
