摘要
一种已经获得国家发明专利授权的新型摆动导杆式抽油机由电动机、减速器、曲柄、滑块、摆动导杆、机架和钢绳等构成,通过曲柄上的滑块在导杆导轨上的滑动,带动导杆以机架为支点做上下摆动,从而实现抽油机的上下冲程。由于滑块在导杆导轨上的滑动,使得曲柄对导杆作用力随悬点载荷大小的变化而自行调整,曲柄轴净扭矩始终处于最佳状态,净扭矩曲线非常平缓,载荷不均匀系数CLF趋近于1,大大降低了电动机的装机功率,电动机输出功率均匀性得到了极大的提高。
A new mode swing crank-slide bar beam pumping unit which has been awarded a national patent composes of motor, reducer ,crank, slider, guide rod ,frame and wire rope. Up and down stroke is performed by slider moving along guide rod guide apparatus resulting guide rod up and down movement against supporting point of pumping frame. Crank automatically adjusts torque according to the changes of hanging point loading when slider moves along guide rod. This maintains the net torque of brace axis always at its best condition. The net torque curve is very smooth and uneven loading factor CLF value approaches one. The new mode swing crank-slide bar beam pumping unit dramatically decreases electromotor installed power and obviously improves the evenness of electromotor output power.
