Abstract
The utility model provides a tubular tool for the underground of oilfields and a miniature horizontal tension and compression test device for the tests of other miniature tubular tools, which adopts the art that the hydraulic station is connected with the high pressure hydraulic pipelines, and two fixed chucks are welded on the experiment bench, two movable chucks are connected with the guiding axle through the axle groove of the fixed chucks to form the miniature horizontal tension and compression test device, thereby solving the tension and compression test problem of tubular tool for the underground of oilfields and other miniature tubular tools. The technical proposal of the utility model is that axle holes and axle grooves are arranged inside the fixed chucks, and bar clasps for adjusting the inner diameters of the chucks are used to assemble specimens with different diameter. The utility model is mainly characterized in that the structure is simple, the cost is lower, experimental expense is lower, and the utility model can be widely used for the tension and compression test of tubular tool for the underground of oilfields and other miniature tubular tools.
Description
Technical field:
The utility model relates to a kind of horizontal small tension and compression testing device that a kind of oil field down-hole tubular tool and other small-sized tubular tool test are used.
Background technology:
Domestic existing tensile and compression testing machine generally all is large-scale or medium-sized stronger specificity all being arranged or can only carry out single stretching or compression test at present, and test specimen is had relatively high expectations.Existing tensile and compression testing machine can not be applicable to the tension and compression test of down-hole, oil field tubular tool.Employed down-hole tubular tool is different from the component of machine of other industry in the existing oil play, these instrument external forms are elongated, length and vary in diameter scope are bigger, underground work inclement condition, the tension and compression testing device of a kind of suitable down-hole of urgent need development tubular tool.
The utility model content:
Can not satisfy of the requirement of down-hole, oil field tubular tool in order to overcome existing tensile and compression testing machine to the tension and compression test, this just requires to develop a kind of small-sized tension and compression test instrument of transporting be convenient to flexibly, the utility model provides a kind of horizontal small tension and compression testing device, this test unit not only is fit to the tension and compression test of down-hole, oil field tubular tool, also be fit to the tubular tool tension and compression test of other industry, this test unit can well be tested the physical strength of tubular tool, especially tensile and compressive strength, and it is accurate to detect data.
The technical scheme that its technical matters that solves the utility model adopts is: with the high-pressure and hydraulic pipeline Hydraulic Station is connected with fluid cylinder in this device, and fixedly chuck I and fixedly chuck II be welded on the experimental stand, fixedly chuck inside is provided with axis hole and axle sleeve is housed, the chuck axis cover is connected on the axis of guide by axially passing fixedly for movable chuck I and movable chuck II, between the two apart from constant, with fixing chuck gap variable.Also have the clip of regulating the chuck internal diameter in addition, clip is contained in the chuck outside when doing tension test, is contained in the test specimen that the inboard is used for assembling different-diameter when doing compression test.During test according to test specimen length, diameter and draw, pressure condition is contained in test specimen on the chuck, open the Hydraulic Station switch, promote reversal valve handle (draw, press oppositely), treat to regulate when test specimen is stressed surplus valve (not unclamping the reversal valve handle) and observe tensimeter, reach predetermined pressure, after voltage stabilizing (time is by the decision of test specimen performance) test is finished, open surplus valve, oppositely promote the reversal valve handle, make system decompression, take off test specimen.
The beneficial effects of the utility model are, this apparatus structure is simple, and cost is low, and the specimen test expense is low, and the sample dimensions scope that this device is suitable for is bigger, and adjustable in pressure is convenient to field test.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Among the figure 1, Hydraulic Station, 2, fluid cylinder, 3, movable chuck I, 4, fixing chuck I, 5, fixing chuck II, 6, movable chuck II.
Embodiment:
In Fig. 1, Hydraulic Station 1 is connected with fluid cylinder 2 usefulness high-pressure and hydraulic pipelines, and fixedly chuck (I) 4 and fixedly chuck (II) 5 be welded on the experimental stand, fixedly chuck (I) 4 and fixedly chuck (II) 5 inside be provided with axis hole and axle sleeve be housed, the chuck axis cover is connected on the axis of guide by axially passing fixedly for movable chuck (I) 3 and movable chuck (II) 6, between the two apart from constant, with fixing chuck gap variable.Also have the clip of regulating the chuck internal diameter in addition, the test specimen that is used for assembling different-diameter is tested.
