一种磁力复位棘爪的棘轮式超越离合器,加装在游梁式抽油机上,通过超越动作自动追踪和适应抽油机光杆载荷与配重间的动态变化,实现了抽油机的动态平衡。超越动作与动态平衡的结果是:管柱震荡减弱,凡尔性能改善、柱塞有效行程增加,出现超冲程、超冲次,由此达到增加油井产液量、提高泵效的目的;同时,有功能耗降低,系统效率提高。这些结果已经被河南油田的现场应用实例所验证。

A ratchet-type overrunning clutch with magnetic resetting pawl is installed on the beam pumping unit, and the dynamic balance of the pumping unit is realized by automatically tracking and adapting the dynamic change between the load of the sucker rod and the counterweight through the overtaking action . Beyond the action and dynamic balance of the results are: the weakening of the tubing string, the performance of the Vernier improve the plunger effective stroke increases, the emergence of over-stroke, overshoot, thereby increasing the production of oil wells to improve pump efficiency purposes; the same time, Reduced power consumption, system efficiency. These results have been verified by field application examples in Henan Oilfield.
