Abstract
The utility model relates to a mill micron antiseptic pumping rod, which comprises a body. Heads are arranged on two ends of the body, and outer screws for connecting are arranged on the head. Mill micron antiseptic coating with metal mill micron powder is arranged on the outer of the body and head. Metal mill micron powder is arranged in the mill micron antiseptic coating. Mill metal micron powder, whose grain diameter is dozens of mill microns, has special medical, physical and mechanical properties. The grain diameter of metal mill micron powder is little. The mill micron antiseptic coating has the advantages that impermeable ability is strong, adhesive force is high, and corrosion resistance and anti-scaling are good. A compact composite bed is formed on the surface of the body and head on the pumping rod. Therefore, the pumping rod, which comprises the mill micron antiseptic coating with the metal mill micron powder, has the advantages that impermeable ability, wear preventive, anti-scaling and wax deposition-proof are all excellent, and service life is long.
Description
Technical field
The utility model relates to a kind of sucker rod, particularly a kind of composite bed of sucker rod body of rod outer wall surface.
Background technology
Sucker rod is the vitals of sucker rod pumping equipment, and it gives the transmission of power of oil pumper the oil well pump of down-hole.Sucker rod has the body of rod, and there is the bar head at the two ends of the body of rod, has on the bar head to connect to use external screw thread.Sucker rod will contact the well liquid in the oil well when the oil pumping operation, contain H in the well liquid in the oil well

2The corrosion of O, mould and other comprehensive corrosion factors, after use a period of time, sucker rod can lose efficacy because of being denuded and corroding.In order to improve the performance of the corrosion-resistant of sucker rod and abrasion, when making sucker rod at the body of rod of sucker rod and the compound one deck composite bed of outer wall surface of bar head, in order to improve the erosion resistant and the corrosive nature on sucker rod surface.In the prior art, the compound metal level of the useful electric plating method of composite bed of the body of rod of sucker rod and bar head outer wall surface, the amorphous alloy layer that the method for useful hot spraying is compound, the also compound nickel-phosphorus alloy coating of the method for useful chemical plating.Corrosion-resistant and the abrasion performance of these composite beds is not very high, along with oil well is more and more darker, the environment of down-hole is more and more harsher, and these composite beds can not satisfy the requirement for anticorrosion of present sucker rod, make that the corrosion-resistant of these sucker rods and abrasion performance are not high, reduce the application life of sucker rod.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of excellent corrosion-resistant and long nano anti-corrosive sucker rod of abrasion performance, application life that has.
The utility model is realized with the following method.
The nano anti-corrosive sucker rod has the body of rod, and the two ends of the body of rod have the bar head respectively, has on the bar head to connect to use external screw thread, is compounded with the nano anticorrosive coating layer with metal nano powder at the body of rod and bar head outer wall surface.
At the body of rod of sucker rod and the method for bar head outer wall surface composite nano-coating layer be: with the method for sandblast the body of rod and the bar head outer wall surface of sucker rod are carried out processing of rust removing earlier, according to the cleaning method of steel surface preliminary treatment standard before the application, the body of rod and the bar head outer wall surface of sucker rod are carried out oil removal treatment again; Method with spraying, brushing or dip-coating is compounded with the nano anticorrosive coating layer with metal nano powder in the body of rod and the bar head outer wall surface of sucker rod then.
The utility model has metal nano powder in the used nano anticorrosive coating of compound tense.As everyone knows, the particle diameter of metal nano powder is in tens nanometers, have special chemistry, physical and mechanical property, the metal nano powder particle diameter is minimum, the composite bed that the nano anticorrosive coating of making can form the densification of excellent performance in the body of rod and the bar head outer wall surface of sucker rod, make the compound sucker rod with nano anticorrosive coating layer of metal nano powder of the body of rod and bar head outer wall surface have excellent corrosion-resistant and abrasion performance, application life is longer.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the schematic diagram of nano anti-corrosive sucker rod;
Fig. 2 is the A-A schematic cross-section of Fig. 1.
The specific embodiment
Among Fig. 1, Fig. 2, the nano anti-corrosive sucker rod has the body of rod 1, and the two ends of the body of rod have bar head 2 respectively, has on the bar head to connect with external screw thread 3, is compounded with the nm-class Ti polymer paint layer 4 with nano-ti powder at the body of rod and bar head outer wall surface.
Titanium is the extraordinary metal material of a kind of corrosion resistance, and above-mentioned nm-class Ti polymer paint is the new function material that carries out chemical bonding and chemisorbed formation with titanium nano powder and organic polymer.Have that the impermeabilisation ability is strong, adhesive power is high, characteristics such as corrosion resistance and good, anti-scaling property are good.The sucker rod that the body of rod and bar head outer wall surface are compounded with nm-class Ti polymer paint not only has excellent corrosion-resistant and abrasion performance, and application life is longer, also has the performance of good antiscale property and anti-wax deposition.
Claims (2)
