4.Working Principle

●Setting: Run the tubing to the scheduled depth, rotate the tubing left, owing to the friction between the centralizer spring and the casing, the center tube and the slip carrier rotate relatively, the upper cone and the lower cone move face to face through the square screw of the center tube, the slip move radial and anchor the casing.

●Releasing: Rotate the tubing right, the upper cone and the lower cone move in the opposite position through the square screw of the center tube, the slip move radial and release the anchoring with the casing by the elastic force of the slip spring.

●In addition: The straight pull emergency shear release provides release force adjustment with shear pins if the catcher cannot be retrieved normally.

5.Product Feature

●Operate simply, the left rotation to set the catcher and right rotation to release it.

●The double-grip slip anchors the tubing to prevent upward and downward movements, increases pump efficiency and lowering maintains costs.

●The large inner diameter provides access for wireline tools and other equipment.

●The straight pull emergency shear release provides release force adjustment with shear pins if the catcher cannot be retrieved normally.

●Prevent the fatigue fracture of the tubing, reduces fishing costs.

●Compact, maintain easily.
