Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of hollow rod anti-wear erosion protection system, can effectively prevent the abrasion and corrosion of hollow rod, extends repair time and the application life of hollow rod.
The anti-wear erosion protection system of a kind of hollow rod, mainly be comprised of rubber seal, internal thread box cupling, steel pipe, zinc-aluminium-cadmium alloy pipe, external screw thread box cupling five parts, described internal thread box cupling is provided with the first female adapter, internal thread box cupling boss and the second female adapter; The external screw thread box cupling is provided with the first male connection, external screw thread box cupling boss, the second male connection and sealed groove; Each integral body naturally of described internal thread box cupling and external screw thread box cupling is threaded connection, and passes through rubber seal rings for seal; Steel pipe and zinc-aluminium-cadmium alloy pipe is installed between internal thread box cupling and external screw thread box cupling.
Above-mentioned steel pipe and zinc-aluminium-cadmium alloy pipe box is in the second female adapter, the first male connection and the second female adapter are threaded connection together, by being arranged on the rubber seal rings for seal on sealed groove, zinc-aluminium-cadmium alloy pipe and steel pipe strap are between internal thread box cupling boss and external screw thread box cupling boss.
Above-mentioned the first female adapter and hollow rod male connection are threaded connection together, by being arranged on the rubber seal rings for seal on sealed groove, the second male connection and hollow rod female adapter are threaded connection together, by being arranged on the rubber seal rings for seal on sealed groove.
The beneficial effects of the utility model are: the anti-wear erosion protection system of hollow rod has successfully solved the serious problem of hollow rod erosion corrosion, corrosion and the wearing and tearing of hollow rod have been reduced, extend the application life of hollow rod, reached the purpose of expection; And the anti-wear erosion protection system of this hollow rod can freely be assembled, freely dismantle, and anti-wear anticorrosive can be changed, and can extend the application life of the anti-wear erosion protection system of hollow rod.And the dimensional parameters of the internal thread box cupling in the anti-wear erosion protection system of hollow rod and external screw thread box cupling and technical data all dimensional parameters and the technical data with the hollow rod of same specification is identical, the manufacturer of hollow rod can oneself produce the internal thread box cupling and the external screw thread box cupling is assembled, a set of equipment both can be produced hollow rod, can produce again internal thread box cupling and the external screw thread box cupling of the anti-wear erosion protection system of hollow rod, not only convenient but also economical, the convenience of rationally bringing production and using of design.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of internal thread box cupling;
Accompanying drawing 3 is structural representations of external screw thread box cupling;
Accompanying drawing 4 is structural representations of hollow rod;
In upper figure: rubber seal 1, internal thread box cupling 2, steel pipe 3, zinc-aluminium-cadmium alloy pipe 4, external screw thread box cupling 5, the first female adapter 6, internal thread box cupling boss 7, the second female adapter 8, the first male connection 9, external screw thread box cupling boss 10, the second male connection 11, sealed groove 12, hollow rod female adapter 13, hollow rod male connection 14.
The specific embodiment
1-4 by reference to the accompanying drawings, the anti-wear erosion protection system of hollow rod that the utility model is mentioned is further described:
The anti-wear erosion protection system of a kind of hollow rod, mainly be comprised of rubber seal 1, internal thread box cupling 2, steel pipe 3, zinc-aluminium-cadmium alloy pipe 4, external screw thread box cupling 5 five parts, described internal thread box cupling 2 is provided with the first female adapter 6, internal thread box cupling boss 7 and the second female adapter 8; External screw thread box cupling 5 is provided with the first male connection 9, external screw thread box cupling boss 10, the second male connection 11 and sealed groove 12; Each integral body naturally of described internal thread box cupling 2 and external screw thread box cupling 5 is threaded connection, by rubber seal 1 sealing; Steel pipe 3 and zinc-aluminium-cadmium alloy pipe 4 is installed between internal thread box cupling 2 and external screw thread box cupling 5.
Wherein, steel pipe 3 and zinc-aluminium-cadmium alloy pipe 4 is enclosed within the second female adapter 8, the first male connection 9 and the second female adapter 8 are threaded connection together, by being arranged on rubber seal 1 sealing on sealed groove 12, zinc-aluminium-cadmium alloy pipe 4 and steel pipe 3 are stuck between internal thread box cupling boss 7 and external screw thread box cupling boss 10.Zinc-aluminium-cadmium alloy pipe prevents the corrosion of hollow rod by anode loss protection; the outside dimension of steel pipe is greater than the maximum outside diameter size of hollow rod; in the moving up and down of hollow rod, steel pipe and tube inner wall friction prevent the hollow rod wearing and tearing.
In addition, the first female adapter 6 is threaded connection together with hollow rod male connection 14, by being arranged on rubber seal 1 sealing on sealed groove 12, the second male connection 11 is threaded connection together with hollow rod female adapter 13, by being arranged on rubber seal 1 sealing on sealed groove 12.
During use, first assemble the anti-wear erosion protection system of hollow rod, then female adapter and hollow rod male connection are linked together, male connection and hollow rod female adapter are linked together, and the anti-wear erosion protection system of hollow rod just is connected between two hollow rods like this.due to the external diameter of steel pipe greater than the maximum outside diameter of hollow rod (hollow rod maximum outer through to locate be exactly female adapter place of hollow rod), when so hollow rod moves up and down in oil well, the steel pipe that the surface is sprayed with nickel molybdenum high-abrasive material replaces hollow rod female adapter and tube inner wall friction, effectively prevent the wearing and tearing of hollow rod, zinc-aluminium-cadmium alloy pipe prevents the corrosion of hollow rod by anode loss protection in fluid, both are in conjunction with effectively having prevented the abrasion and corrosion of hollow rod, extended the application life of hollow rod, reached the purpose of expection.And the anti-wear erosion protection system of this hollow rod can freely be assembled, freely dismantle, anti-wear anticorrosive can be changed, can extend the application life of the anti-wear erosion protection system of hollow rod, namely facilitate and saved again resource, bring huge economic benefit.
