摘　　要：应用波动方程描述抽油杆柱的振动 ,考虑地面传动机构的传动效率对复合平衡游梁式抽油机各节点功率的影响 ,建立了地面各单元分效率与电动机实耗功率的计算机仿真方法 .仿真计算结果表明 ,与单独的曲柄平衡游梁式抽油机相比 ,在满足平衡条件的前提下 ,由于四杆机构的平均运行效率随游梁平衡重质量的增加而增大 ,其节电率也随游梁平衡重质量的增加而增加 ,故复合平衡游梁式抽油机具有一定的节电效果 .由于复合平衡游梁式抽油机不能明显减小曲柄轴转矩波动 。The vibration of the rod string is described by the wave equation, and the computer simulating method of various unit efficiencies and the power consuming of the motor have been set up based on the effect of driving efficiency of various mechanisms on the power of various joints of a compound balance beam pumping unit. The results show that compound balance beam pumping unit can reduce the electric energy consumption of the unit compared with a crank balance beam pumping unit. At the balance state, the electric energy saving ratio becomes higher with the beam balance weight heaved when the average running efficiency of the four\|bar linkage mechanism is getting higher with the weight of a beam balancing weight raised. Because the varying extent of the net torque of the crankshaft of a compound balance beam pumping unit can be not reduced greatly, compound balance beam pumping unit can not reduce the rated power of the motor.
