It is recommended that centralizers be used on the rods for reduction of rod string and oil well tubing wear. The centralizers can be fixed; they can be installed directly on the rod body by pressure die casting method. The rotating centralizers are located between the locks on the rod body and can rotate on the same. Apart from ensuring wear protection, centralizers prevent deposits formation inside oil well tubing and increase the time between well overhauls.
The sucker rod moves up and down in the tubing, due to the elastic deformation of sucker rod, rod and oil tube wall is easy to make friction, ti makes sucker rod break off easily, sucker rod centralizer has strong flexibility, touched with the tubing wall can reduce the friction of rod and tube, and can be increase production life of pumping unit. The centralizer is connected with sucker rod , the outsid diameter of centralizer is bigger than coupling outer diameter,so that can make the function of centralize. The centralizer is made of high strength wear-resistant material, and touched with the tubing to reduce the abrasion to achieve the purpose of anti-abrasion.
