Sliding sleeve sucker rod centralizer
The underground petroleum machinery of the righting sucker rod reduces the friction between the rod and the tube and enhances the oil recovery life of the pumping unit.
The sliding sleeve sucker rod centralizer consists of a core rod, a sliding sleeve and a joint.
1. Spray a thick metal lubrication film on the surface of the centralizer by spray welding.
2. The material of the metal lubricating film is nickel-based alloy powder with a nickel content of 60% and other components such as chromium, boron, silicon, and the like.
3. With three wear-reducing surfaces, the line contact of the traditional centralizer is changed to face contact. The contact is more complete and the anti-bias effect is more obvious.
