自调平衡游梁式抽油机的研制

Development of Beam Pumping Unit for Automatic Balance Adjustment

通过接收随机安装的抽油机平衡监测仪器的指令,使具有电驱动调平衡装置的游梁式抽油机可以实现自动平衡调节。自调平衡装置采用齿轮齿条传动,实现了游梁配重相对游梁的前后移动,从而对井口载荷的变化进行平衡调节,使抽油机达到最佳的平衡效果,达到节能的目的。

Through the instruction of instrument which is monitoring the balance of pumping unit,the beam pumping unit achieved the automatic balance adjustment,which has a balance device driven by a motor.The device uses the gear and rack to realize the beam counterweight to move forward and backward compared with the beam,then to balance the change of the well-load,so the pumping unit realized the best balance effect and achieved energy saving.
