Non-metallic hydraulic anchor
Non-metallic hydraulic anchor
Work / Adjustment Principle：
The working principle is to apply a certain pressure from the liquid inside the oil pipe, the anchor claw compresses the spring, so that the anchor claw extends radially, and the anchor claw is firmly stuck on the inner wall of the casing, generating strong frictional resistance and playing the role of anchoring the oil pipe; releasing the liquid pressure inside the oil pipe, the anchor claw is automatically withdrawn and unstuck.
Technical characteristics：
• The non-metallic hydraulic anchor FJSM FZ 114*50mm is different from the traditional conventional metal hydraulic anchor in that the core of the anchor claw is made of oil- and acid- and alkali-resistant rubber with integral vulcanization. The anchor claw overcomes the spring force under the action of liquid pressure and extends radially, generating strong frictional resistance through the contact between the rubber and the inner wall of the casing, thus playing the role of anchoring the pipe column. Since the contact with the inner wall of the casing is non-steel, it will not damage the inner wall of the casing, which effectively extends the service life of the casing and greatly reduces the production cost.
•The non-metallic hydraulic anchor FJSM FZ 114*50mm is set with tensile limit, when abnormalities occur, the upper part of the anchor claw can be pulled off by the limit tonnage, thus reducing accidents such as stuck wells.
