文章对其几何尺寸与平衡参数进行了优化设计，证实该机型曲柄轴的均方根扭矩比异相型减少了31.2％，最大扭矩减少了35.3％，平衡效果显著。

The geometric dimensions and balance parameters of the beam pumping units are optimized. As a result, Me is re- duced 31.2% and Mnmax is reduced 35.3% than phased balance.

但净扭矩曲线存在负值，建议增加曲柄二次平衡，设计成复合平衡型抽油机。

But net torque curve of crankshaft exists negative . The compound balance beam pumping units is put forward.
