Abstract

The utility model relates to a tube and rod wear resistance tester for simulating field eccentric wear motion of tubes and rods, which is applicable to wear resistance tests of couplings in any size by replacing a connector of a lever with a coupling. The tube and rod wear resistance tester mainly comprises a transmission conversion mechanism (a crank and a connecting rod), a pressurizing mechanism, a spray mechanism and the like, wherein the transmission conversion mechanism realizes linear reciprocation of a tube or a rod, the pressurizing mechanism can be utilized to apply vertical radial force to the tube or the rod, and when friction heat temperature is too high in the process of friction, the spray mechanism can automatically start a pump to spray oil-gas mixture to the tube or the rod for cooling. An automatic stoppage control portion is further designed, frequency of friction stroke can be preset on demand, and wear condition can be tested accurately according to a digital display device. The tube and rod wear resistance tester is simple and reasonable in structure, easy in production and manufacture, simple and safe in operation, high in automation level, and realer and more accurate in testing results, and has fine popularization and application value.

Description

Pipe bar abrasion wear test machine
Technical field
The utility model relates to a kind of check sucker-rod coupling rub proofness testing machine, particularly a kind of eccentric wear exercise test device of real simulation field pipes bar.
Background technology
Along with the arrival of oil well high water-cut stage mining phase, the friction factor of pipe bar surface of contact significantly increases, the eccentric wear aggravation.The workload that eccentric wear increases accounts for 20% ~ 30% of the whole maintenance workloads of oil well, has caused the significant wastage of human and material resources.Therefore the wearing quality that increases sucker-rod coupling becomes and reduces one of way of managing the bar maintenance capacity.Because box cupling is various in style, the material otherness is bigger, therefore to the higher requirement of having researched and proposed in its wearing and tearing serviceable life.In the present friction wear testing machine, have kind of testing machine can only do left and right sides straight reciprocating motion, what kind was mainly carried out in addition is the rotation wear test, and its test specimen is for rotatablely moving.These two kinds of wear-resisting machines can not accurately be simulated the state of reciprocating type side-abrasion of rod string.
Summary of the invention
Goal of the invention:In order to overcome problems of the prior art, real simulated field condition more, the utility model provide a kind of debugging flexibly, the novel more accurately pipe bar abrasion wear test machine of check.
Technical scheme:The technical scheme that its technical matters that solves the utility model adopts is: this utility model is mainly by the cooperatively interact to-and-fro movement of real simulation pipe bar of transmission throw-over gear, pressing mechanism, spraying mechanism, pressing mechanism is connected with the pressurization lever at the two ends, the left and right sides of main frame, and the end that the round nut of regulating pressing mechanism can drive the lever that pressurizes upwarps or presses down.Thermopair has been installed on the tubing wall to be connected with temperature controller.Can be to applying radial force between box cupling and the oil pipe in the friction by the debugging pressing mechanism, real simulation the eccentric wear phenomenon of pipe bar; When the varying in size of box cupling, can change the joint of pressurization lever and box cupling; Adopt spraying mechanism, when the oil pipe temperature surpasses behind setting, the thermopair on the tubing wall can be passed to temperature controller with information, and temperature controller can start the water pump cooling of spray structure automatically, and unnecessary oil water mixture can flow back to oil tank and recycles.This testing machine also can carry out Based Intelligent Control, can set the spurt number of times in advance, and can auto stop when reaching given jig frequency.
Beneficial effect:By pressing mechanism, eccentric wear that can real simulated pipe bar; By changing the joint of lever and box cupling, can make this testing machine be suitable for various box cuplings; By spraying mechanism, can prevent that heat of friction is too high and box cupling is out of shape under the eccentric wear state, the too high actual environment that does not also meet the motion of pipe bar of temperature; By control system, can control different box cuplings and under equivalent environment, under the equal jig frequency, rub.The result who records like this can be more accurate.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further introduction, but not as to qualification of the present utility model.
Crank 1 and connecting rod 2 pass to roller 3 then with the to-and-fro movement that is in line of the movement conversion of motor sense of rotation.Before the startup, make 4 liftings of oil pipe test specimen come to contact with box cupling 7 according to the box cupling 7 debugging handwheel 5 that varies in size.Turn round nut 16 during the debugging pressing mechanism earlier, up by screw rod 17 power transmission sleeve pipes 19, an end that drives pressurization lever 23 upwarps, like this, axle center with roller 3 is that fulcrum applies radial force between box cupling 7 and oil pipe 6, its support reaction is pressed to the ground backing plate by spring 20, spring born work arbor 21, roller 22, and downward modulation round nut 18 is with required pressure locking.Thermopair 11 is housed in the oil pipe 4, and temperature controller can start pump 15 coolings of stand 12 belows when heat of friction surpasses setting value, and unnecessary oil water mixture can flow to circulating oil tank 6 and flow back to oil tank 14 along recirculatory pipe 10 and recycle.This device can also carry out auto stop control, and control section is equipped with sensor for countering and numeric display unit, can show the friction jig frequency, and can auto stop when reaching given jig frequency.
