| 摘 要： | 为了平抑电动机扭矩负荷曲线的波峰和波谷，减小配置电动机的额定功率，提高抽油机系统的工作效率，提出了一种同轴二次曲柄平衡游梁抽油机方案，在常规游梁抽油机一次曲柄平衡的基础上，增加一个同轴不同转速的二次曲柄平衡结构，不仅解决了二次平衡曲柄的安装空间问题，而且还能充分发挥二次平衡效果。对CYJ10-3—53HB型抽油机的计算表明，可以使输出轴峰值扭矩降低38％，节电33．7％。

| Abstract: | In order to stabilize wave crest and trough of torque curve of the electric motor, the matching power of electric motor was decreased to raise work efficiency of the beam pumping unit system, a concept of balanced coaxial second crank was proposed, that is a coaxial secondary counterbalancing structure with different rotation speed was added on the basis of ordinary beam pumping unit. It could not only solve the problem of the second crank installation space, but also improved the efficiency of the secondary crank counterbalancing. The calculation of the CYJ10-3-53 beam pumping unit showed the decrease of torque peak value by 38% and the energy consumption by 33.7%. |
