【Abstract】 The main problems in research and design pumping jacks are: how to adjust pumping jacks balance effect in order to save energy and improve its balance and longevity and how to solve the problem of high depletion and low efficiency. It advanced the method of joint and partnership between two pumping jacks and fully analyzed it. Torque diagram of brace-shaft was shown, according to the balance of the joint and partnership between two pumping jacks by computer, comparing with beam pumping units of out-of-phase and routine, the displacement. After researching the graphs, a conclusion can be reached: negative torque could be diminished basically, peak value of torque decreased, capacity of electromotor lowered and cost decreased and the disadvantages of beam pumping jack, such as high depletion and low efficiency, could be solved. Thus, this can realize direct transmission of energy, decrease maximum of torsional moment and loss of energy, and improve the efficiency so that pumping jacks’ work-condition can be improved.更多还原
