Introduction of Oil Driller
Beam-pumping unit is widely used in the oil industry. Beam-pumping unit is a modified four-bar linkage, the whole structure just like a balance, one side is pumping load, and another side is the counterweight load for balancing. If the pumping load and the counterweight load have the same torque or their torque change consistently, then the oil driller can work continuously with a small external power. That means the balance performance is the key factor of energy saving. If the balance ration is 100%, the power from motor only used to lift 50% weight of liquid column and overcome the friction force, the lower of the balance ratio, the bigger power from the motor is required. The pumping load is changed all the time, but the counterweight cannot make the same change together with the pumping load.
