Compound balance beam pumping unit on the basis of the conventional beam pumping unit is increased under the barbell rigid device, reduce the torque changes smoothly, not only to reduce the peak torque power saving effect, and greatly improved the working conditions of pumping unit reducer, increased the ability to work, prolong the service life of equipment. It integrates all the advantages of the conventional beam pumping unit, with reliable performance, the characteristics of simple structure, convenient operation and maintenance.
