Dual Horsehead Pumping Unit

The pumping unit with dual horsehead is a new type unit developed on the basis of conventional unit, which has features of low stroke, low power consumption and high efficiency as well as feature of conventional units.

Features

1. The pumping unit with dual horsehead is a new type unit developed on the basis of conventional unit, which has features of low stroke, low power consumption and high efficiency as well as feature of conventional pumping units.
2. A rear horsehead of which curvature radius is variable is designed at the rear end of walking beam. Flexible connection is designed between the rear horsehead and equalizer so that the pumping unit is a variable four-bar linkage to change torque curve of load on the polished rod for better congruence with the balanced torque curve. This will reduce the net torque peak value of gear reducer, eliminate minus torque and lower motor power.
3. Flexible linkage eliminates 90° "dead angle constraint" occurring on the conventional unit and faxed four-bar linkage. The pivot angle of walking beam increases by a factor of 30%~50%.
4. There are two working styles: the rotor angle of crank in upstroke is bigger than that in downstroke when the cranks rotate clockwise; and the rotor angle of crank in downstroke is bigger than that in upstroke when the cranks rotate counterclockwise so that the upward speed is faster than the downward speed.
