曲柄行星轮式抽油机定轮的优化设计

曲柄行星轮式抽油机是一种新型无游梁抽油机,在保持高可靠性的前提下,可缩小体积、节约占地,满足长冲程、大载荷的工况要求,并获得显著的节电效果。定轮的曲线形式决定着该抽油机的节能效果。通过对阿基米德螺线、偏心圆曲线和双圆弧曲线的对比,确定了该抽油机定轮的最佳曲线型式。对比得出,曲柄行星轮式抽油机的运动和动力特性均优于双驴头抽油机。

Optimized Design of Fixed Wheel Pumping Unit Using Crank Planetary Gear

Using Crank planetary gear in pumping unit is the new type which has no Beam.On keeping the advantage of high reliability,it can reduce volume,save area,fulfill the working condition of long stroke and big load,and obtain the effect of saving electricity.The curve shape on the fixed wheel which was mounted on the pumping unit determined the effect of energy saving.Based on the comparison Archimedes solenoid,eccentric circular curve and double circular curve,the best curve of the fixed wheel was obtained.By ...
