Through comparing different driving schemes a structure that combines wrapping connector driving with rigid driving is adopted to obtain a 5 to 8 meter long stroke thus may increase the efficiency of pump and decrease driving motor power at the same time .

对比了各种传动方式，认为采用柔性与刚性相结合的传动方案，可使抽油机获得5～ 8m的冲程，是提高泵效和降低电机功率的有效途径。
