Description of drawings
Be in conjunction with the accompanying drawings and embodiments specific embodiments of the present invention to be described in detail below.
Fig. 1 is the vertical view of vertical type sucker rod centralizer friction wear testing machine;
Fig. 2 is the front view of vertical type sucker rod centralizer friction wear testing machine;
Fig. 3 is the charger structural drawing.
Embodiment
Vertical type sucker rod centralizer friction wear testing machine involved in the present invention, mainly by motor 1, cycloidal-pin wheel speed reduction unit 2, eccentric wheel 3, fuel tank 4, oil pump 5, oil pipe 6, wellbore hole simulator 7, crank pin 8, down angle sheave 9, adhesive tape 10, go up angle sheave 11, go up fixed bar 12, charger 14, fixed bar 15, weight 16 etc. are formed down.
Propulsion system drive eccentric wheels 3 rotations by motor 1 through cycloidal-pin wheel speed reduction unit 2 as shown in Figure 1, and eccentric wheel 3 is by centralizer 13 to-and-fro movements between crank pin 8 and adhesive tape last fixed bar 12 of 10 drives that is fixed thereon and the following fixed bar 15.As shown in Figure 2, on the polished rod in the middle of centralizer 13 is fixed on by last fixed bar 12 and following fixed bar 15, the polished rod of last fixed bar 12 and following fixed bar 15 and centre is to be threaded.The last action edge of centralizer is provided by propulsion system, and following action edge is provided by the weight 16 of following fixed bar 15 bottoms
Shown in 3, half oil pipe 18 is fixed on the support column 17 by screw 21, is fixing back-up block 20 by screw 19 between support column 17 and half oil pipe 18, changes the centralizer that different back-up blocks 20 can be adapted to different size.In order to accelerate the process of the test of rubbing wear, need between half oil pipe and centralizer, apply certain radial force.The radial load of centralizer is provided by charger 14, weight 29 is added in load by steel cable 28 upper end of lever 26, by leverage, apply bigger acting force for crossbeam 25 in the lower end of lever 26, load post 24 and support column 17 and half oil pipe 18 is fixed together by screw thread, radial load is affacted the outer cylinder surface of centralizer 13 by half oil pipe 18.Charger can load on the centralizer both sides simultaneously about the centralizer symmetric arrangement.For the ease of the radially adjustment of support column 17, by the fixing ball 23 of gland 22, can guarantee in centralizer wearing and tearing back compensation radial play automatically in support column 17 top and bottom, constant to guarantee the radial load that is added on the centralizer.
