Embodiment
Be illustrated in figure 1 as the disclosed embodiment of the utility model.By shaft coupling 26, transmission shaft 27,23 rotations of drive eccentric wheel, eccentric wheel 23 is made the plane motion (see figure 2) by crank pin 22 drivening rods 21 to propulsion system by motor cycloidal-pin wheel speed reduction unit 25.Connecting rod 21 other ends are connected with orienting lug web member 20, make its moving linearly on guide rail 19.Connecting rod 21 drives pull bar 17 and carrying slide plate 15 reciprocating (see figure 3) on roller bearing 12 by the slide block bearing pin on the orienting lug web member 20 18.Wherein, guide rail 19 links to each other with support 49 by screw, and linear slider 47 and bearing 46 are installed on the support 49, and by screw attachment, and connecting rod 21 is by bearing and bearing pin 44 (see figure 6) that links to each other with bearing 46.Because roller bearing 12 is seated on the casing by bearing 35 and bearing seat, can reduce friction, prolong the serviceable life of part.It is reciprocating that carrying slide plate 15 drives half oil pipe 14 of portion fixed thereon, realizes the mutual friction mutually between half oil pipe 14 and the centralizer 11.
Centralizer 11 is fixed on the centralizer anchor clamps 10, centralizer anchor clamps 10 link to each other with support column 8 by cotter axle 9, support column 8 is set upright guiding by orienting sleeve 7, orienting sleeve 7 is sitting on the bearing 6, charger 1 is added to load between centralizer 11 and half oil pipe by support column 8, centralizer anchor clamps 10 by loading lever 5, realizes that different load loads.The cross section be trapezoidal slide rail 29 by screw retention on clamp body 39, and (see figure 4) in the dovetail groove of embedding slide block 30, slide block 30 middle parts are with the screw swivel nut that is being connected, swivel nut and leading screw 37 form transmission, and the two ends of leading screw 37 are screwed (see figure 4) on clamp body 39 by bearing 42 and bearing seat 38; Fixing addendum cone 36 by nut in slide block 30 bottom holes, when clockwise rotating leading screw 37, two swivel nuts drive slide block 30 and addendum cone 36 and move to the centre and clamp centralizer 11; When rotating counterclockwise leading screw 37, two swivel nuts drive slide block 30 and addendum cone 36 and move to both sides and unclamp centralizer 11.
A supporting positive cover 42 respectively is housed up and down in the orienting sleeve 7, and to 8 centralizing function (see figure 5)s of support column, supporting positive cover 42 is connected with orienting sleeve 7 by holding screw 41, and supporting positive cover 42 adopts high-abrasive material, and is convenient to change.Adopt clearance fit between supporting positive cover 42 and the support column 8, can move down the wearing and tearing of automatic compensation centralizer.The support column 8 tops fore-set 40 that has been threaded, fore-set 40 upper ends contacts with loading lever 5, and fore-set 40 highly can pass through threaded adjusting, to adapt to the centralizer of different size.Two bolts are housed in the hole on fore-set 40 tops, are convenient to carry the centralizer anchor clamps 10 of support column 8 and its underpart.Loam cake 4 is left and right sides two halves structure, is convenient to dismounting.When changing centralizer, removable half loam cake on the left side down rotates counterclockwise 37, two swivel nuts of leading screw and will drive slide block 30 and addendum cone 36 and move to both sides and unclamp centralizer 11.
During test, can adopt screw pump to provide the liquid that contains heterogeneity and temperature (see figure 7) according to the actual production fluid of different oil wells, comprise a certain proportion of oil, gas, water, husky potpourri are provided by lubricating oil pipe line 3, and be heated to the temperature that needs, make test as far as possible near the oil well actual condition.
Owing to work as the down-hole oil tube size not simultaneously, just correspondingly adopt the centralizer of different size, thereby, for the centralizer of different size, should change the oil pipe of corresponding size during test.Can dismantle the gib screw of briquetting 31 in this device, take off briquetting 31,, realize the centralizer of different size is carried out friction-wear test with regard to half oil pipe 14 of replaceable different size and the semicircle support ring 32 of corresponding internal diameter.
Embodiment of the present utility model is not limited to this example, and other for example various elements are installed, fit system, and the different situations such as select for use of charger all can adopt other mode.In a word, for those of ordinary skills conspicuous substitute and conversion all in protection domain of the present utility model.
