Embodiment Construction

[0021] As shown in Fig. 1, it is an embodiment disclosed by the present invention. The power unit is driven by the motor cycloid reducer 25 through the shaft coupling 26, the transmission shaft 27, and the eccentric wheel 23 rotates, and the eccentric wheel 23 drives the connecting rod 21 through the crank pin 22 for plane movement (see Figure 2). The other end of the connecting rod 21 is connected with a guide block connector 20 to make it move linearly on the guide rail 19 . The connecting rod 21 drives the pull rod 17 and the carrying slide 15 to reciprocate on the roller 12 through the slider pin 18 on the guide block connector 20 (see FIG. 3 ). 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 is connected by screw, and connecting rod 21 links to each other with support 46 through bearing and bearing pin 44 (see Fig. 6 ). Because the roller 12 sits on the casing through the beari...

Abstract

The invention relates to a device for carrying friction and abrasion test of centralizer with various dimensions by applying mechanical radial loading applied method. It is characterized in that the power device (24) is connected with eccentric wheel (23) by crank pin (22) and connecting rod (21); the connecting rod (21) drives pulling rod (17) and bearing slipping plate (15) move to and fro on rolling shaft (12); half oil pipe (14) is fixed on the upper of bearing slipping plate (15); the centralizer (11) is fixed on the centralizer fixture (10); the centralizer fixture (10) is connected with support column (8) by transverse pin (9); the support column (8) is centralized and guided by guiding sleeve (7); loading device (1) applies load to the place between the centralizer (11) and the half oil pipe (14) by loading lever (5), support column (8) and centralizer fixture (10). The project is provided with simple structure, easy operation, low cost and easy extension. It can be set in laboratory as the quick evaluation method in developing process of centralizer.

Description

technical field [0001] The invention belongs to the technical field of friction and wear testing of petroleum machinery, in particular to a device for performing friction and wear tests of centralizers of various sizes by using a mechanical radial load application method. technical background [0002] As the major oilfields in eastern my country have successively entered the medium-high water-cut development period, oilfield exploitation is becoming more and more difficult. In order to improve oil recovery, polymer flooding technology has been rapidly developed in my country's oilfields in recent years. Practices over the past few years have shown that polymer flooding has achieved significant oil-increasing and water-increasing effects, but the non-Newtonian nature of the produced fluid causes severe eccentric wear of the sucker rod string and tubing, and the phenomenon of rod breakage increases significantly. Significantly shortened. In order to avoid eccentric wear betwe...
