油管旋转器延长了油管的使用寿命油管旋转器由地面设备和井下设备构成，由抽油机发动机直接驱动。用旋转油管悬挂器代替固定的地面油管悬挂器，安装在游梁上的转换减速装置能把抽油机的往复运动转变成旋转运动，通过驱动缆绳把这种旋转运动提供给由齿轮传动的旋转油管悬挂...
Tubing rotator prolongs tubing life Tubing rotators consist of surface and downhole equipment driven directly by the pumping unit’s engine. Instead of a fixed floor tubing hanger with a rotating tubing hanger, a transfer decelerating device mounted on the beam converts the pumping unit’s reciprocating motion into a rotating motion, which is provided by the driving cable to a geared rotation Tubing hanging ...
