Embodiment 1

[0025] Embodiment 1 A kind of test method of sealing ring friction and wear, comprises the following steps:

[0026] 1) Fix the lower test piece on the lower fixture, and keep the central axis of the semi-cylindrical groove of the lower test piece consistent with the movement direction of the horizontal reciprocating device;

[0027] 2) After inserting the upper test piece into the arc-shaped receiving groove between the upper fixture seat and the clamping cover, control the axial compression rate of the upper test piece by adjusting the adjusting bolt and fix it on the upper fixture; adjust the two-dimensional adjustable The position of the moving table is such that the central axis of the semi-cylindrical end face of the upper fixture and the central axis of the semi-cylindrical groove of the lower specimen are in the same vertical plane;

[0028] 3) Add the test medium into the medium tank and set the test temperature, normal load and friction frequency through the control ...

Embodiment 2

[0030] Example 2 A test device constructed according to the test method described in Example 1, including a machine base 1, a medium tank 2, an upper fixture 3, a lower fixture 4, a temperature console 5, a horizontal reciprocating device 6, and a two-dimensional adjustable moving Platform 7 and data acquisition control system, the two-dimensional adjustable mobile platform 7 is fixed on the upper part of the base 1, and the lower part of the two-dimensional adjustable mobile platform 7 is equipped with a two-dimensional force sensor 71; The two-dimensional mechanical sensor 71 fixedly clamps the upper fixture 3 of the upper test piece 31; the medium tank 2 is installed above the horizontal reciprocating device 6, and the medium tank 2 is fixed to clamp the lower test piece. The lower fixture 4 of the part 41, the test medium 21 is filled in the medium tank 2; the horizontal reciprocating device 6 is fixed on the base 1; the two-dimensional adjustable mobile table 7, the The h...

Abstract

The invention discloses a frictional wear test method and a frictional wear test device for a sealing ring. The method comprises the following steps of: 1) fixing a lower test piece on a lower clamp; 2) embedding an upper test piece into a cambered accommodating slot, and adjusting an adjustment bolt to control the axial compression rate of the upper test piece; 3) adding a test medium into a medium slot, and setting test temperature, a normal load and a friction frequency; and 4) controlling a bidimensional adjustable mobile table and a horizontal reciprocating motion device, and calculating a friction coefficient between the upper test piece and the lower test piece. The device comprises a machine seat, the medium slot, an upper clamp, a lower clamp, a temperature control console, a horizontal reciprocating motion device, the bidimensional adjustable mobile table and a data acquisition control system, wherein the bidimensional adjustable mobile table, the horizontal reciprocating motion device and the temperature control console are electrically connected with the data acquisition control system. The frictional wear test method and the frictional wear test device have the beneficial effects that a working condition of the sealing ring is really simulated; in a test process, the friction is synchronously and dynamically acquired; and the friction interface damage evolution property and the influence rule of the sealing ring are accurately analyzed.

Description

technical field [0001] The invention relates to a test method for friction and wear of a sealing ring and a test device thereof. Background technique [0002] The reliability and stability of sealing technology has become a key factor for the safe and stable operation of modern process industry equipment. According to whether there is relative movement between the sealing coupling surfaces, the seal can be divided into static seal and dynamic seal; and according to the role of the seal in the sealing device, there are main seal and auxiliary seal. However, no matter it is used as the main seal or the auxiliary seal, the dynamic seal must not only bear the pressure of the medium, but also withstand the friction and wear caused by relative motion, so as to ensure a certain sealing performance and meet the requirements of motion performance. For example, the hydraulic pressure as the main seal, the seal between the piston and the cylinder in the pneumatic cylinder, the seal be...
