摘　　要：常规游梁式抽油机存在负扭矩、能耗大、效率低的问题。本文设计了二次平衡装置,对抽油机的二次平衡作了深入的理论分析,给出了通过抽油机扭矩曲线信号叠加,实现抽油机净扭矩的正值化的方法,同时降低一次平衡曲柄轴净扭矩的两个峰值,从而降低了电机的功率,提高了电机的效率,节能达到15%～20%。该技术具有很好推广价值。Conventional beam pumping unit exists problems of negative torque, energy consumption and low efficiency. This paper designs a second balancing device, and theoretically analysis the second pumping unit balance deeply, in this paper signal superposition of pumping torque curve is given, achieved the method of positive net torque, and reduced the two peaks of balanced crank shaft net torque, while reducing the efficiency of motor power, enhancing the efficiency of the motor, ultimately 15% -20% of energy is saved. The technology has a good value of promotional.
