In fact, the working principle of pumping unit is same to the pumping well at home. It also use swabbing action of piston rod (sucker rod) to pump the oil. Then send away the oil through the buried pipeline. The only difference is that the action of the pull rod is driven by an electric motor.

At present, there are many kinds of forms of pumping unit. The common seen on the TV is a machine with a big fan of iron that, and move back and forth.

The appearance design of the pumping unit is not to save energy, but to reduce the influence of the power grid. Because we know that when the sucker rod is falling, the motor is not working, while electricity back. There are too many pumping unit in oilfield, and the power of these feedback can make the power grid has a serious distortion. So nowadays the pumping unit is equipped with a feedback brake or a variety of ways such as inverse feedback.

After the introduction of variable speed drive, the stroke frequency of the oilfield pumping unit can be adjusted and lower stroke can be adjusted respectively according to the downhole condition and the speed of the upper. It can improve the pump's full coefficient and reduce the leakage of the pump to get the maximum oil output.
