螺杆泵抽油杆防脱器
本技术提供的是螺杆泵抽油杆安全装置,具体地说是螺杆泵抽油杆防脱器。
技术介绍
螺杆泵上端连接有抽油杆,通常在抽油杆上装置防脱器,现有的防脱器只能起到防止抽油杆与螺杆泵之间脱落的作用,不能实现螺杆泵杆柱系统卡泵以及断脱时进行扭矩释放,防止伤人事故发生。现有防脱器的结构,抽油杆转轴通过端盖安装在筒体的筒体内孔内,其内设有阿基米德曲线壁,在穿入筒体内孔位置的转轴一侧通过弹簧安装有键,在筒体的另一侧设有连接孔,在连接孔的环周壁上设有连接孔内螺纹。
技术实现思路
为了解决螺杆泵抽油杆防脱和能量释放的问题,本技术提供了螺杆泵抽油杆防脱器。该防脱器通过在扭矩释放轴与筒壳内轴肩设置扭矩调整环,解决螺杆泵抽油杆防脱和能量释放的技术问题。本技术解决技术问题所采用的方案是:筒壳为圆管形,一端设有筒壳端盖,另一端设有螺杆泵连接螺纹,在筒壳内设有扭矩释放轴腔,扭矩释放轴腔内设有扭矩释放轴渐开线槽;具有抽油杆变扣接头连接螺纹和抗扭轴扳手空间的抗扭轴设有密封槽,在密封槽内装有密封环,并且装有圆锥滚子轴承;扭矩释放轴另一端连接有转动轴,转动轴通过单向推力球轴承装在筒壳内,转动轴通 ...
