Abstract
The utility model discloses a prevent splitting carbon fiber continuous sucker rod that resistance to wears, including the carbon fiber sucker rod body of rod, the carbon fiber sucker rod body of rod is the one -way carbon fiber sucker rod body of rod. One -way carbon fiber sucker rod rod body outer wall parcel glass fiber winding layer. The outside parcel form in glass fiber winding layer is to the glass fiber layer. The outside parcel polytetrafluoroethylene wearing layer in one -way glass fiber layer. The utility model provides a sucker rod rise down with the production process in atress splitting, the body of rod problem of wearing and tearing.
Description
Technical field
This utility model relates to sucker rod, a kind of wear-resistant carbon-fiber continuous rod of anti-splitting.
Background technology
Along with going deep into of oil field development, roofbolt is caused greatly to be easily corroded and under oil well pump, the most limited cannot being adapted to corrodes well, deep-well or the requirement of ultradeep well work operating mode owing to conventional steel sucker rod is weak to burn into autologous density.And the generation of carbon fibre pumping rod solves the problems referred to above.But existing carbon-fiber continuous rod easily cleaves owing to reasons in structure exists stress, the problem such as the most wear-resistant.For solving the problems referred to above, the method can found at present has 2 kinds.Method one: add one-way glass fiber and epoxy resin layer outside carbon fiber, this structure plays certain wear-resistant effect, but the problem that the body of rod still suffers from splitting；Method two: join special centering guide, but centralizer is fixing difficult, easy to fall off.Therefore, need to again the structure of carbon-fiber continuous rod be redesigned, to solve the splitting of body of rod stress, the most wear-resisting problem.
Summary of the invention
The purpose of this utility model is to provide a kind of wear-resistant carbon-fiber continuous rod of anti-splitting, solve sucker rod remove with stress splitting in production process, body of rod abrasion problem.
In order to reach above-mentioned purpose, this utility model have employed following technical scheme, a kind of wear-resistant carbon-fiber continuous rod of anti-splitting, and including the carbon fibre pumping rod body of rod, the described carbon fibre pumping rod body of rod is the unidirectional carbon sucker rod body of rod.Described unidirectional carbon sucker rod body of rod outer wall parcel glass fiber winding layer.Described glass fiber winding layer outer wrap one-way glass fibrous layer.Described one-way glass fibrous layer outer wrap PTFE anti-wear layer.
Compared to prior art, this utility model has the advantages that
1, after the body of rod uses glass fiber winding cladding can effectively prevent carbon fiber pressurized, microcrack extends into the whole sucker rod body of rod；
2, glass fibre unidirectional ply can play help carbon beam and bears, insulate and isolate and slow down well immersion and enter to corrode the effect of carbon beam, while can also reduce the cost of sucker rod.
3, outermost layer cladding PTFE anti-wear layer, improves the anti-wear performance of sucker rod.
4, the outer three layers of cladding of carbon fiber bar effectively slow down well immersion and enter speed, improve body of rod decay resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wear-resistant carbon-fiber continuous rod of anti-splitting of the present utility model.
In figure: 1, the unidirectional carbon sucker rod body of rod；2, glass fiber winding layer；3, one-way glass fibrous layer；4, PTFE anti-wear layer.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides reference and purposes of discussion, is not used for being any limitation as this utility model.
According to Fig. 1, a kind of wear-resistant carbon-fiber continuous rod of anti-splitting, a kind of wear-resistant carbon-fiber continuous rod of anti-splitting, including the carbon fibre pumping rod body of rod, the described carbon fibre pumping rod body of rod is the unidirectional carbon sucker rod body of rod 1.Described unidirectional carbon sucker rod body of rod outer wall parcel glass fiber winding layer 2.Described glass fiber winding layer outer wrap one-way glass fibrous layer 3.Described one-way glass fibrous layer outer wrap PTFE anti-wear layer 4.
Being wound around successively and unidirectional cladding two-layer alkali-free glass fibre and a strata tetrafluoroethene wearing layer outside the described unidirectional carbon sucker rod body of rod, wherein winding glass layer plays and prevents the carbon fiber body of rod pressurized from occurring being extended down to the whole sucker rod performance effect of impact of the whole body of rod outside crackle；One-way glass fiber play slow down well immersion enter to corrode carbon beam speed, help carbon beam bear and reduce the effect of body of rod holistic cost；The PTFE anti-wear layer of high tenacity primarily serves the effect improving body of rod anti-wear performance, also functions to the effect preventing the body of rod from corroding simultaneously.
Making of the present utility model and use process be:
(1) first carbon fibre precursor is immersed in epoxy resin and auxiliary agent, forming the unidirectional carbon fibre pumping rod body of rod 1 by pultrusion molding process under uniform temperature (150-250 DEG C), then the body of rod 1 is outer forms glass fibers winding layer 2 and one-way glass fibrous layer 3 by Wrapping formed and unidirectional pultrusion molding process the most respectively；
(2) after the pre-solid molding of carbon fibre pumping rod of cladding three layers, by the body of rod by being soaked with the grinding tool of melted politef, and curing molding process is carried out.Finally the carbon-fiber continuous rod finished product bar of cladding four layers is wrapped on cylinder.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
Claims (1)
1. the wear-resistant carbon-fiber continuous rod of anti-splitting, including the carbon fibre pumping rod body of rod, the described carbon fibre pumping rod body of rod is the unidirectional carbon sucker rod body of rod；Described unidirectional carbon sucker rod body of rod outer wall parcel glass fiber winding layer；Described glass fiber winding layer outer wrap one-way glass fibrous layer；It is characterized in that, described one-way glass fibrous layer outer wrap PTFE anti-wear layer.
