Based on such problems as cracking and breaking of walking beam in running,a type of resistance measuring technology is used to make static and dynamic stress measurement for leading components such as walking beam and rear horsehead,and the results show that the walking beam is subjected to a tensile stress by driving holes.
双驴头抽油机是油田广泛采用的一种节能型抽油机,针对运行中产生的与后驴头连接处的游梁裂纹、断裂问题,利用电阻应变测量技术对该型抽油机游梁、后驴头等主要承载构件进行了现场静、动态应力测试。
The auxiliary balancing device for beam pumping units is a movable counterbalance installed on the walking beam,which reciprocates along the back arm of the beam under the action of the linkage and results in good balancing effect.
游梁式抽油机的移动式游梁辅助平衡装置是在游梁上安装一个可移动的平衡块，通过抽油机连杆及辅助连杆（拉杆）带动平衡块沿游梁后臂往复运动，改变平衡块在游梁后臂上的位置，从而获得较好的平衡效呆。
