In order to solve the technical problem, the technical scheme adopted by the utility model is as follows: wear-resisting paraffin removal special sucker rod centralizer of sulfur-proof includes: the metal rod body and the cylindrical synthesis of rotation setting on the metal rod body are right the body the spiral discharge orifice of three interior water conservancy diversion evenly is provided with on the inner wall of the body is right in the cylindrical synthesis evenly be provided with a plurality of cylindrical flat bosss on the body surface is right in the cylindrical synthesis.
In order to better solve the technical problem, the further technical scheme adopted by the utility model is as follows: the cylindrical synthetic centralizing body is prepared by mixing and injection molding of high-molecular polyethylene and carbon fiber.
In order to better solve the technical problem, the further technical scheme adopted by the utility model is as follows: and a wear-resistant and oxidation-resistant metal powder coating is arranged on the surface of the metal rod body.
The utility model has the advantages that: above-mentioned special sucker rod centralizer of wear-resisting paraffin removal of sulfur-proof, synthetic body of rightting adopts cylinder overall structure, has evenly distributed's little boss on the cylinder, clears away oil pipe inner wall wax stone when the sucker rod up-and-down motion of being convenient for. The spiral discharge orifice of interior water conservancy diversion that has designed three evenly distributed on the body inner wall is right in the synthesis, and when the crude oil that spills over passed through from the spiral discharge orifice of interior water conservancy diversion, helical structure can produce the revolving force, and the body is right in the promotion is rotatory on the metal body of rod, reaches the inner wall and does not have the dead angle paraffin removal, when lightening the effect of resistance from top to bottom of the sucker rod, can also guarantee to right the body and evenly wear. The surface of the metal rod body is provided with the wear-resistant and oxidation-resistant metal powder coating, so that the ultrahigh strength of the metal rod body is ensured, and the metal rod body is prevented from breaking and falling off due to the rotary wear of the centering body; the cylindrical synthetic centralizing body is prepared by mixing and injection molding of high-molecular polyethylene and carbon fiber, and the high-molecular polyethylene is used, so that the high-temperature resistance and corrosion resistance of the cylindrical synthetic centralizing body are obviously enhanced, the thermal deformation temperature of the cylindrical synthetic centralizing body reaches 390 ℃, and the cylindrical synthetic centralizing body is insoluble in acid-base H2S has stronger corrosion resistance and can contain H in acid and alkali2S and high-temperature well conditions are safe to use, the wear resistance is 3-5 times of that of a metal material, the composite centralizing body has lubricating property, the friction coefficient of the cylindrical composite centralizing body is 0.011-0.015, and the elongation at break is more than or equal to 750 percent. The carbon fiber is used, so that the tensile strength of the cylindrical synthetic centralizing body can reach 1600MPa, the strength is higher than that of a metal material, the fiber flexibility and fatigue resistance are realized, the effect of removing wax deposited on the inner wall of the oil pipe is better, and the oil pipe cannot be embrittled, broken and detached. The injection-molded cylindrical synthetic centralizer has extremely high strength and wear-resistant self-lubricating performance, so that wax blocks on the inner wall of the oil pipe can be efficiently removed, the oil pipe cannot be excessively abraded, the service life of the centralizer is prolonged, and the centralizing failure and disconnection accidents caused by the abrasion of the centralizer are prevented.
