Embodiment 1

[0034] A plurality of 12K bundles of T300 carbon fiber filaments are drawn out from the wire drawing frame 1. Driven by the traction of the traction device 9, the T300 carbon fiber bundles enter the dipping tank 2 to fully impregnate the glue solution. The traction speed of the traction device is 1000mm / min. The surface of the T300 carbon fiber tow fully impregnated with epoxy resin glue is covered with a narrow glass fiber tape under the action of the glass fiber tape coating device 3, and under the power of the traction device, it enters the sucker rod body forming mold 4 together for the initial Curing, curing and molding temperature according to the order of entering and exiting the mold: 140°C\160°C\200°C, molding time is 2 minutes, and the diameter of the final formed carbon fiber composite sucker rod is 8mm. The formed carbon fiber composite continuous sucker rod that has been cured for the first time enters the secondary curing furnace 5 for secondary curing molding. Th...

[0036] A plurality of 12K bundles of T700 carbon fiber filaments are drawn out from the wire drawing frame 1. Driven by the traction of the traction device 9, the T700 carbon fiber bundles enter the dipping tank 2 to fully impregnate the glue solution. The traction speed of the traction device is 600mm / min. The surface of the T700 carbon fiber tow fully impregnated with epoxy resin glue is covered with a narrow glass fiber tape under the action of the glass fiber tape coating device 3, and under the power of the traction device, it enters the sucker rod body forming mold 4 together for the initial Curing, curing molding temperature according to the order of entering and exiting the mold: 150 ° C \ 170 ° C \ 210 ° C, the molding time is 3 minutes, and the diameter of the carbon fiber composite sucker rod body after the final molding is 9 mm. The formed carbon fiber composite continuous sucker rod that has been cured for the first time enters the secondary curing furnace 5 for se...

Embodiment 3

[0038] A plurality of 6K bundles of T700 carbon fiber filaments are drawn out from the wire drawing frame 1. Driven by the traction of the traction device 9, the T700 carbon fiber bundles enter the dipping tank 2 to fully impregnate the glue solution. The traction speed of the traction device is 300mm / min. The surface of the T700 carbon fiber tow fully impregnated with polyurethane resin glue is covered with a narrow glass fiber tape under the action of the glass fiber tape coating device 3, and under the power of the traction device, it enters the sucker rod body forming mold 4 for initial curing , the curing molding temperature according to the order of entering and exiting the mold is: 155 ° C \ 175 ° C \ 200 ° C, the molding time is 2.5 minutes, and the diameter of the carbon fiber composite sucker rod body after the final molding is 8 mm. The formed carbon fiber composite continuous sucker rod that has been cured for the first time enters the secondary curing furnace 5 for...

Abstract

The invention discloses a sucker rod with a composite spiral abrasion-resistant layer, a manufacturing device and a manufacturing method. The abrasion-resistant layer made of fiber reinforced thermoplastic resin-matrix composite materials covers the surface of the sucker rod, reinforced fibers of the abrasion-resistant layer are aramid fibers or ultrahigh molecular weight polyethylene fibers, resin matrixes of the abrasion-resistant layer are made of one of polyethylene, polyamide, polyphenyl ether, polysulfone, polyphenylene sulfide, polytetrafluoroethylene, polyoxymethylene or polyether ether ketone; the reinforced fibers can be wound on the surface of the sucker rod in such a manner that narrow bands made of two-dimensional fabrics are wound on the surface of the sucker rod. The sucker rod, the manufacturing device and the manufacturing method have the advantages that the sucker rod with the structure is excellent in deflection abrasion resistance, the abrasion-resistant layer on the surface of the sucker rod has certain toughness and strength, the problem of crack in sucker rod winding procedures due to poor mechanical properties of pure thermoplastic resin can be solved, micro-pore meshed structures are subjected to strong interface bonding owing to the self-protection layer made of the thermoplastic composite materials and a sucker rod body, and the self-protection abrasion-resistant layer can be prevented from slipping and layering from the surface of the sucker rod.

Description

technical field [0001] The invention relates to oil production equipment and manufacturing technology in the petroleum industry, in particular to a sucker rod with a composite spiral wear-resistant layer, a preparation device and a preparation method. Background technique [0002] Due to the complex and diverse types of oil wells in China, the depth of oil wells and the downhole environment are also deteriorating with the increase of production scale. Therefore, although traditional steel sucker rods have been gradually replaced by composite material sucker rods, this high-performance material The high-quality sucker rod inevitably faces the problems of corrosion and eccentric wear. At present, the composite sucker rods used in China mainly include two types: glass fiber reinforced resin-based composite sucker rods and carbon fiber reinforced composite sucker rods. At present, FRP sucker rods have low fatigue strength and are easy to break, so they cannot adapt to the highl...
