Examples

Referring to fig. 1 and 2, the present embodiment provides a detection system 100 (hereinafter referred to as a detection system 100) for performing a tightness test on a floating ring seal assembly, which includes a floating ring seal general purpose tester 1, a controller 2, a cooling device, an air supply device, an oil supply device, a driving device, and a camera device 3. The following description is with reference to the orientation of fig. 1.

The floating ring seal universal tester 1 (hereinafter referred to as tester 1) is a key component of the whole detection system 100, and a workpiece to be detected is arranged in the floating ring seal universal tester to simulate the actual working condition of the workpiece, so that the detection is completed. In this embodiment, the floating ring seal universal tester 1 is mounted on a chassis 9.

Referring to fig. 3, 4 and 5, the floating ring seal universal tester 1 includes a tester body 10 and a main shaft 11; the tester body 10 is provided with a test cavity 1011 (shown in FIG. 4), and the spindle 11 is rotatably arranged on the axis of the test cavity 1011; the interior of the test cavity 1011 is also provided with a taper sleeve 12 and an adapter ring 13.

Referring to fig. 5, the taper sleeve 12 is detachably sleeved at the front end of the main shaft 11 and is synchronously and rotatably connected with the main shaft 11; the adapter ring 13 is fixed on the periphery of the taper sleeve 12, and the outer ring wall of the adapter ring 13 is tightly attached to the inner cavity wall of the test cavity 1011 to be connected in a sealing manner.

A floating cavity (not marked in the figure) for mounting a workpiece to be tested is formed between the outer cylindrical surface of the taper sleeve 12 and the inner annular wall of the adapter ring 13; the taper sleeve 12 and the adapter ring 13 can be replaced to match workpieces to be measured with different sizes.

The workpiece to be detected is a floating ring sealing assembly F to be detected, exemplarily, the floating ring sealing assembly comprises two floating rings which are oppositely arranged along the same axis, and an elastic part, such as a wave spring, is compressed between the two floating rings. The floating ring seal assembly F is a conventional seal product in the art, and the specific structure and specifications thereof are well known and will not be described herein.

The floating cavity formed between the taper sleeve 12 and the adapter ring 13 actually simulates the working condition of a workpiece to be detected, so that the sealing performance of the floating ring sealing assembly F can be detected before leaving a factory, and the basic function of the invention is realized.

The taper sleeve 12 and the adapter ring 13 can be replaced to match workpieces to be detected with different sizes, that is, the thickness of the taper sleeve 12 and the thickness of the adapter ring 13 have different specifications, so that a floating cavity formed by the taper sleeve 12 and the adapter ring is changed along with the thickness of the adapter ring 13, and the floating ring sealing assembly has different sizes, so that the floating ring sealing assembly F with different sizes can be matched and subjected to sealing detection.

When detecting the floating ring seal assembly F of different sizes, only need with taper sleeve 12 and adapter ring 13 dismantle the replacement can, need not to change other parts or whole tester 1, compare in prior art and can only detect the floating ring seal assembly F of a certain specific size, the tester 1 of this embodiment has stronger commonality. The taper sleeve 12 and the adapter ring 13 in the embodiment are detachably mounted, and replacement is also extremely convenient.

Referring to fig. 5, preferably, the taper sleeve 12 is in taper fit connection with the main shaft 11.

Specifically, the front end of the main shaft 11 is a conical surface, the inner surface of the conical sleeve 12 is also a conical surface, and the matching cone angles θ of the two conical surfaces are consistent and range from 7 ° to 12 °.

There are two considerations in setting the angular range:

firstly, under the condition that the self-locking taper angle of the steel part is smaller than 7 degrees, namely the fit taper angle theta is smaller than 7 degrees, the taper sleeve 12 and the main shaft 11 can have a self-locking phenomenon, and the taper sleeve and the main shaft are combined too tightly to be convenient for disassembly, so the fit taper angle theta between the taper sleeve and the main shaft cannot be smaller than 7 degrees;

secondly, if the fitting taper angle θ exceeds 12 °, the taper sleeve 12 and the spindle 11 are not firmly joined, and it is not ensured that the two are always concentric in a high-speed motion, and the two are easily loosened, so that the fitting taper angle θ cannot exceed 12 °.

Specifically, the shaft end of the main shaft 11 is further provided with a screw hole, when assembling, the taper sleeve 12 is sleeved at the front end part of the main shaft 11, the two taper surfaces are tightly connected, and the two are firmly connected together through a fastening screw 121; preferably, a compression ring 122 is padded between the fastening screw 121 and the taper sleeve 12.

It should be understood that the spindle 11 and the taper sleeve 12 are not limited to the above-mentioned taper fit connection, and for example, the spindle 11 and the taper sleeve 12 may be connected by a spline structure, so that the spindle 11 and the taper sleeve 12 can be detachably connected without affecting the concentricity of the spindle and the taper sleeve.

Specifically, in the present embodiment, the tester body 10 includes a main housing 101, an inner cover 102, and an outer cover 103, and the outer cover 103 is fixedly covered on the front end surface of the main housing 101.

Specifically, a stepped hole penetrating through the front surface and the rear surface of the main housing 101 is formed in the main housing 101, the stepped hole includes a large-diameter section and a small-diameter section (as shown in fig. 4), the large-diameter section forms the test cavity 1011, and the front end portion of the main shaft 11, the taper sleeve 12 and the adapter ring 13 are all installed in the test cavity 1011; the small diameter section is used for installing the right end of the main shaft 11, a bearing 104 is respectively installed at the front and rear positions of the small diameter section, and the main shaft 11 is installed on the bearing 104 (as shown in fig. 6).

When assembled, the inner cover 102 abuts the outer side of the adapter ring 13 for fixing the axial position of the adapter ring 13.

Referring to fig. 7, preferably, the inner hole wall of the inner cover 102 extends to one side to form a ring of flange 108, and the flange 108 is inserted into the inner hole of the adapter ring 13 during assembly, so as to provide better fixing effect. Of course, the inner hole wall of the adapter ring 13 may be adaptively configured, for example, a circle of groove is formed, and the depth of the groove is consistent with the thickness of the flange 108, so as to ensure that the flange 108 is just embedded into the groove during assembly.

The adapter ring 13, the taper sleeve 12 and the main shaft 11 are fixed in position and are in a concentric position relation; after the floating ring sealing assembly F is installed in the floating cavity, the initial position of the floating ring sealing assembly F is not 100% concentric with the three parts, and the floating ring sealing assembly F falls down due to the self gravity, the circle center position of the floating ring sealing assembly F is slightly lower than the circle centers of the three parts, and the root of the falling is that the inner hole of the floating ring sealing assembly F is slightly larger than the outer diameter of the taper sleeve 12. When the main shaft 11 rotates at a high speed, the floating ring seal assembly F is kept in a floating state separated from the main shaft 11, and the floating ring seal assembly F keeps a concentric position relation with the main shaft 11.

In the starting and stopping stages of the tester 1, friction is generated between the outer cylindrical surface of the taper sleeve 12 and the inner cylindrical surface of the floating ring sealing assembly F, and the outer cylindrical surface of the taper sleeve 12 is damaged in the long term, so that a wear-resistant layer is formed by spraying tungsten carbide or chromium oxide on the outer cylindrical surface of the taper sleeve 12, the wear resistance of the taper sleeve 12 can be improved, and the service life of the taper sleeve is prolonged. Generally, the inner cylindrical surface of the floating ring sealing component F is made of carbon graphite materials, and the floating ring sealing component F is high in hardness and strong in wear resistance.
