DTA torque anchor
1 Application
Torque anchor is a kind of anchor tool which specially designed for screw pump, simple structure,
easy to use.
2 Structures
It is mainly consists of upper sub, anchor, centralizer, reed and mandrel etc. When the screw pump
rotates, torque anchor can effectively avoid the tubing rotate. It has the characteristics of simple
structure, simple installation, working flexible, safe anchoring, widely used in anchoring of screw
pump and anchor of tubing of tubular pump
.
3 Working principle
When the screw pump rotates, the rotor rotates thus drive the stator, upper sub and mandrel to
rotate, anchor opens, anchors on the casing, anchoring completed. When the screw pump stops,
stator releases energy under spring action, anchor closes under the contractility of reed, releasing
completed.
