The new intelligent hydraulic pumping unit consists of two parts: the main engine and the hydraulic cylinder (bracket). The main engine and the hydraulic cylinder are connected by hydraulic oil pipes to form a complete working unit for two oil wells. The main engine includes servo hydraulic power motor, bidirectional quantitative pump, hydraulic oil cylinder and other devices.

After starting up, the servo hydraulic power motor drives the bidirectional quantitative pump, which directly drives the cylinder body to move. The downward acceleration causes the cylinder rod of one hydraulic cylinder to move downward, and at the same time drives the cylinder rod of another hydraulic cylinder to move upward, just like the lever movement of a seesaw.

During the descent of the hydraulic cylinder rod and the pumping rod, energy is released under the action of downward acceleration, and is transferred to the rising hydraulic cylinder through the hydraulic oil through the bidirectional quantitative pump to drive the cylinder rod to rise. Through this original "hydraulic seesaw" principle, the energy required for the cylinder rod to rise is greatly reduced, thereby achieving the purpose of energy saving.
