Abstract
A hollow sucker rod of composite fiber consists of sucker rod body and metal connector. It features that sucker rod body is ring form rod body prepared by compounding multiple - bundle carbon fiber, super high - intensity glass fiber and PPTA composite material with base of resin, metal connector is bound or wedged on each end of said rod body.
Description
One, technical field:
The present invention relates to the composite fiber hollow rod that a kind of oil exploitation is used.
Two, background technology:
Sucker rod is requisite easily-consumed products in the oil exploitation, and steel sucker rod quality is heavy, increases oil pumper load, and is easily to the oil pipe wearing and tearing, perishable, easily broken taking off.The sucker rod of composite fiber mixing pultrusion has excellent properties such as intensity height, density are little, corrosion-resistant, endurance than traditional sucker rod, can become the renewal product of common steel sucker rod in the oil exploitation.
Three, summary of the invention:
The objective of the invention is provides a kind of with carbon fiber, glass fiber, aramid fiber composite material and matrix resin composite fiber hollow rod from the sucker rod configuration aspects.Overall tensile strength, fatigue resistance, interface binding power, the corrosion-resistant intensity that improves sucker rod, integral body alleviate the sucker rod quality, save electric power.
Technical scheme of the present invention realizes in the following manner:
The present invention is made up of the sucker rod body of rod, metal joint, wedge mechanism, it is characterized in that the sucker rod body of rod is that a cross section by multi-beam carbon-fiber, glass fiber, aramid fiber and the compound pultrusion of matrix resin is the annular sucker rod body of rod.Two ends at the annular sucker rod body of rod are provided with metal joint, and metal joint bonds together securely by the cementing agent and the sucker rod body of rod, or links together by wedge type mechanism.
The two ends metal joint of the sucker rod body of rod also can clamp the sucker rod body of rod by a wedge mechanism, wedge mechanism comprises metal joint, wedge shape box cupling and wedge shape jacketing, male thread is established in the metal joint upper end, the spanner rib is established in the male thread bottom, male thread is established in spanner rib bottom, this male thread bottom is made as the bullet of reducing, bullet is provided with the gingival cyst of mucous gland in the newborn button, wedge shape box cupling upper end is provided with box thread, wedge shape jacketing is embedded in the wedge shape box cupling, and the ring type boss of hollow rod upper end is pressed in the upper end of wedge shape jacketing.
Pultrusion method of the present invention is that usefulness such as carbon fiber wire, superhigh intensity glass fiber, aramid fiber its a kind of or two kinds and above sucker rod are become assignment system.Two kinds and above prescription: carbon fiber+glass fiber and other fiber+matrix resin=100: 60-75: 25～40, matrix resin: curing compound: the ratio preparation of release agent=100: 0.5～10: 0.5～10, glass fiber and carbon fiber are arranged in proportion to be put on the guide frame, two fibers enter steeping vat by the collection filament plate in proportion, come out to enter the mould that is heating and curing from steeping vat, come out to enter the back curing oven from the mould that is heating and curing, pull out with tractor, through sawing machine is the sucker rod body of rod of 813～11328 millimeters long, two ends fit on metal joint the sucker rod of carbon fiber and glass fiber mixing pultrusion.
The mould that is heating and curing adopts three sections or four sections heating, and each section temperature remains between 80 ℃～160 ℃, and back curing oven adopts two sections or four sections heating, and every section temperature remains between 80 ℃～160 ℃.
Pultrusion speed is 0.2-2m/min.
Compared with the prior art the present invention has the following advantages:
1, tensile strength height, fatigue resistance height, interface binding power are good, corrosion-resistant.
2, in light weight, reduce oil pumper load, saves energy.
3, alleviated the friction of oil pipe and the resistance that oil is flowed.
