摘要： A rotating breech lock rotates tubing to distribute wear caused by a rotating or reciprocating rod of an artificial lift system. The rotating breech lock has a spool that disposes on a wellhead. A bowl element disposes in the spool's bore, and a hanger fits into the spool and lands on the bowl element with a thrust bearing. Above the hanger, a load ring fits against the hanger with a bearing, and a hold-down sleeve and locking pins hold the load ring against the hanger. The spool has a worm that mates with a wheel defined about the hanger so turning the worm by a ratchet or other mechanism rotates the hanger. Internally, the hanger has a bore with opposing shoulders separated by gaps. A mandrel couples to the tubing and disposes up into the hanger. Protrusions or keys on the hanger can selectively align with the gaps and the shoulders depending on how the mandrel is rotated in the hanger bore.
摘要翻译：旋转后膛锁旋转管道以分配由人造举升系统的旋转或往复杆引起的磨损。旋转后膛锁具有置于井口上的阀芯。碗形元件配置在卷轴的孔中，并且衣架装配到卷轴中并且用推力轴承落在碗形元件上。在衣架上方，一个负载环用一个轴承装在衣架上，一个压紧套和一个锁定销把负载环固定在衣架上。阀芯具有与围绕吊架限定的车轮匹配的蜗杆，因此通过棘轮或其它机构转动蜗杆使衣架旋转。在内部，衣架有一个孔，相对的肩膀被间隙分开。芯棒连接到管道上并放置在衣架中。吊架上的突起或钥匙可以根据心轴如何在衣架孔中旋转而选择性地与间隙和肩部对准。
