Abstract: Solar driving auto-balance beam pumping unit was designed and developed to solve the unbalancing conditions of beam pumping unit and reduce the labor intensity of balance-adjusting work. A special tail beam assembly part is installed at the tail of the beam pumping unit that is driven by solar energy and able to adjust the balance weight automatically. The tail beam assembly part includes the solar-driven vernier counterweights and control system. The control system can collect the real-time parameters to figure out the degree of balance and move the counterweights forward and backward according to the degree of balance and adjust the balance of beam pumping unit by means of the wireless transmission method. With a wide scope for balance adjustment, high automation and a modular and plug-in design, this product is highly adaptable for the environments, reliable in safety and stability, and convenient for assembly and calls for a small amount of work for renovation of the work site. It plays an active role in improvement of the field management and reduction of energy consumption.
