Sucker Rod Guides are for pumping well anti-abrasion. They are suitable for pumping well and directional well which above of sucker rod middle point, under the middle point of sucker rod, the rod body with nylon centralizer is working better. 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 increase production life of pumping unit. The centralizer is connected with the sucker rod, the outside diameter of the centralizer is bigger than the coupling outer diameter, so that can make the function of centralizing. 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.
