Our company's novel product, protected by a national invention patent, features an innovative structure representing a major technological breakthrough compared to conventional beam pumps.
Its energy-saving performance surpasses existing energy-efficient pumping units, achieving an average electricity savings rate of 21% per ton of liquid produced per 100 meters.
The machine retains the operational principles of a four-bar linkage pumping unit, ensuring safety and reliability equivalent to conventional pumping units.
High suspension point projection accuracy and slow packing wear in the blowout preventer extend packing service life.
During repair and maintenance operations, the front deflection wheel can be adjusted via the connecting rod to make way, eliminating the need to move the donkey head. This ensures convenient operation and enhanced safety.
The entire machine operates smoothly with stable current fluctuations, and its gearbox torque fluctuations outperform existing conventional beam pumping units.
Structural components are largely identical to front-mounted pumping units, ensuring installation, operation, and maintenance procedures align with conventional units for user-friendly operation.
Crank pins, bearing housings, and other components are interchangeable with conventional pumping units, offering high versatility and facilitating future maintenance.
This model is suitable for long-stroke, low-cycle applications.
