Products Description
This belt-driven pumping unit utilizes a heavy-duty belt for power transmission. The belt’s inherent elastic buffering effect effectively reduces reversing impact during operation, ensuring smooth and stable movement of the sucker rod.
With a torque arm length of only 0.46 meters, the unit significantly lowers torque requirements, allowing for the use of a smaller motor and gearbox. Compared to conventional pumping units, this design achieves energy savings of 10% to 40%, contributing to substantially reduced production costs.
Operational safety is enhanced by the integration of two independent braking systems and an automatic braking device, providing reliable protection under various working conditions.
