我国目前普遍应用的抽汲设备是筒状抽汲胶筒和胶皮密封的防喷盒 ,以钢丝绳为抽汲绳。由于纲丝绳表面有较深的凹槽 ,靠胶皮密封不可能使出井的抽汲绳保持清洁 ,而且筒状抽汲胶筒不能控制载荷 ,往往给设备增加危险 ,同时漏失严重。而ＦＨＥ工具抽汲心轴采用“Ｖ”型胶筒 ,在流体 At present, the pumping equipment commonly used in our country is a tube-shaped spray-proof box with a rubber-sealed barrel and a rubber seal, and a wire rope is a draw-rope. Due to the deep groove on the surface of the wire rope, it is impossible to clean the pumping line of the well by the rubber seal, and the tube can not control the load, which often adds danger to the equipment and causes serious leakage.
