Abstract: In view of the deficiencies of traditional pumping units, this paper proposes a concept of multiple compound balance and conducts test and verification. It is proved that the new method has better counterbalance effect. This paper gives an introduction about the use, structure, technical descriptions, operating principle, technical characteristics, pilot manufacturing and testing, and field application of the new pumping unit, and points out its range of application. It has been awarded with multiple national patents.
