摘要
调径变矩型抽油机将常轨游梁平衡型抽油机的后臂下偏一个角度,变力臂、变配重,实现了变平衡力矩。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。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。
The beam pumping units with adjustable radius and change moment can change balance moment. 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. But net torque curve of crankshaft exists negative . The compound balance beam pumping units is put forward.
