Torque anchor
Torque screw anchor is designed specifically for anti-off tool, the torque anchor consists of anchor body, the card block, card sets, centralizers and other components. Go down the screw anchored to the lower end of the torque when the screw pump, the positive torque produced by rotation of the fixture block, the block and the casing of the card under the action of friction, the card block inversion, the screw stator and the casing wall anchor; when screw stops working, the positive torque disappears under the action of the reverse torque, anchor released automatically. So as to solve the anchoring screw hole Y2 11 type often used in load torque is small packer assemblies during production tubing often tripping problem. Structure is simple, easy to use.
Torque anchor technical parameters as follows, and its connection thread according to contract manufacturing.
