Abstract
A hydraulic petroleum pumping unit with secondary balance weight structure comprises a base, a walking beam, a bracket, a connecting bar, a connecting bar weight, a hydraulic cylinder, a supporting bearing, an upper cross beam, a connecting bearing, an upper connecting bar and a small horsehead. The unit is characterized in that the tail of the walking beam is connected with the small horsehead and the small horsehead is connected with the upper cross beam, the upper connecting bar, the connecting bar and a weight box in order. A cross beam is installed on the connecting bar and a parameter-adjusting beam is installed between the cross beam and the weight box. The hydraulic cylinder is installed below the parameter-adjusting beam. The connecting bar and the weight box form a whole and the supporting bearing is installed at the turn-over point of the connecting bar and the weight box. A weight piece is installed in front of the walking beam. The unit is hydraulically driven, has the characteristics of low power, little wasted energy, few traditional components, little abrasion, long service life, good safety property, good capability of reducing power by over 1/3 and the like and can be widely applied to petroleum extraction process.
