针对抽油机运行过程中,抽油机的底座安装与调整很难完全实现光杆轴线与井口轴线的重合,使得抽油机在运转过程中光杆产生横向随机偏移的实际情况,在对多年来开发系统降低盘根偏磨的做法进行技术检索和分析的基础上,研制出了一种《随动对中抽油井口密封装置》,从根本上解决了盘根单侧偏磨的问题,盘根寿命有了较大幅度的延长,取得了较好的节电降耗效果,具有较好的现场推广应用价值。 In the process of pumping unit operation, the installation and adjustment of the base of the pumping unit is difficult to fully realize the coincidence of the rod axis and the wellhead axis, which makes the pumping rod produce a lateral random offset during operation. In the past years Development system to reduce the partial wear of the packing method for technical retrieval and analysis based on the development of a “follow-up pumping wellhead sealing device,” fundamentally solve the problem of partial unilateral partial wear disk Root life has been more substantial extension, and achieved better energy saving effect, with good site promotion and application value.
