Torsion Anchor

The torque anchor should be installed as close as possible to the stator of the screw pump, and turn the pipe column 3-5 times after reaching the predetermined depth, because the slip under the elastic action of the spring plate, the edge of the slip tooth and the casing wall are in reverse contact, and the effective pipe string is reversed torque caused by the rotation of the rotor on the stator, so as to avoid the pipe string trip.
