Motor Reversing Pump Jack

The motor reversing pump jack is a high efficiency and low energy consumption product. It uses the intelligent analog and digital control and uses the switched reluctance motor as the prime mover which the power factor is cosΦ≈1. As the transmission of the friction wheel is the working mechanism, the mechanical transmission line is short and the efficiency is high. The starting reversion is stable with low impact. The stroke and stroke frequency can be regulated independently and steplessly. The velocity of the up stroke and down stroke of the polished rod can be controlled respectively. Its mechanical efficiency is about two times of the conventional beam pumping unit, its system efficiency reaches to 50%, and energy saving rate is 46%. The product is an ideal pumping unit to replace conventional beam pumpjack.
