偏轮游梁抽油机是一种新型长冲程高效节能抽油机 ,该抽油机与常规游梁抽油机相比的结构特点是游梁尾部装有一个偏轮 ,在偏轮与游梁中心支架之间增加了操纵杆 ,游梁尾部、横梁、操纵杆与偏轮之间用轴承联接而成。通过计算出悬点的位移、速度和加速度并绘制出各曲线 ,对该抽油机运动分析表明 ,最大加速度明显减小及加速度的变化率减小。 Partial beam beam pumping unit is a new type of long-stroke energy-efficient pumping unit, the pumping unit compared with the conventional beam pumping unit structure is characterized by a tail beam beam, The center of the beam between the bracket increased joystick, beam tail, beam, lever and wheel coupling between the bearings made. By calculating the displacement, velocity and acceleration of the hanging point and plotting the curves, the motion analysis of the pumping unit shows that the maximum acceleration is obviously reduced and the rate of change of acceleration is reduced.
