Product Description
Motor reversing pumping unit
- Motor reversing 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 of 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 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.
