Motor Reversing pumping unit

MotorReversing pumping unit is a high efficiency and low energy consumption product. It employs the intelligent analog and digital control and uses the switched reluctance motor as the prime mover, ofwhich 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, realizing the reversion of the motor. 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 that of conventional beam pumping unit. Its system efficiency reaches to 50%, and energy saving rate is about 46%. The product is an ideal pumping unit to replace conventional beam pumping unit.
