Description

Technical Field

[0001] This invention relates to the field of online material performance testing instruments, and in particular to a micro-wear device for a water vapor environment. Background Technology

[0002] With the continuous optimization and adjustment of energy construction and application structures, nuclear power has become an important direction for current and future development. Pipelines and materials used in the nuclear power field need to operate under water vapor and complex loads, placing special requirements on their performance. Fretting wear testing equipment in water vapor environments is used to characterize the wear performance of samples by simulating specific service scenarios. In practical applications, existing water vapor fretting wear testing equipment has the following shortcomings: 1. Low testing efficiency: only one sample can be simulated and tested at a time. Due to the long testing process, material testing and analysis requiring multiple data points necessitates lengthy experiments; 2. Complex sample loading: to reduce the adverse effects of unavoidable positional errors during sample loading, complex loading procedures are required, but the results are not ideal; 3. Poor equipment versatility: to improve testing accuracy, the testing equipment has specific limitations on the sample shape, requiring targeted fixture design based on the sample shape, resulting in high selectivity for the sample shape.

Figure 3 This is a schematic diagram of the structure of the multi-load clamping module in the fretting wear device for a water vapor environment according to an exemplary embodiment of the present invention, as shown below. Figure 2 and Figure 3 As shown, as an optional example, the multi-load clamping module 3 includes a clamp loading plate 31 and multiple clamps 32. The clamp loading plate 31 includes a loading plate body 311 and multiple loading tubes 312 that are integrally connected to the loading plate body 311 and are distributed in a ring on the outer side of the loading plate body 311. The loading plate body 311 is generally ring-shaped, and multiple loading plate assembly slots 3111 are evenly arranged on the outer side of the loading plate body 311.

[0023] Figure 4 This is a partial cross-sectional schematic diagram of the loading disk body in the fretting wear device for a water vapor environment according to an exemplary embodiment of the present invention. Figure 5This is a partial cross-sectional schematic diagram of the loading pipe in a fretting wear device for a water vapor environment according to an exemplary embodiment of the present invention. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the loading tray body 311 has an annular fluid channel 3112, multiple first radial fluid channels 3113, and multiple second radial fluid channels 3114 inside. The multiple first radial fluid channels 3113 and the second radial fluid channels 3114 are distributed along the axial circumference of the loading tray body 311.

[0024] Figure 6 This is a schematic diagram of the fixture in the fretting wear device for a water vapor environment according to an exemplary embodiment of the present invention. Figure 7 This is a cross-sectional structural diagram of the clamp in the fretting wear device for a water vapor environment according to an exemplary embodiment of the present invention, as shown below. Figure 6 and Figure 7 As shown, the clamp 32 includes a clamp body 321 and a clamping end 322 integrally connected to the clamp body 321. Multiple fixing protrusions 323 are arranged annularly on the outer side of the end of the clamp body 321. Multiple positioning posts 324 are correspondingly arranged on each fixing protrusion 323, and the positioning posts 324 match the positioning holes 3123 of the loading tube 312. Multiple curved through grooves 325 are arranged annularly on the clamping end 322, and the inner wall of the clamping end 322 is wavy.

[0025] It should be noted that the clamp 32 in this embodiment can be quickly fixedly assembled in the loading tube 312 of the loading tray body 311, and can be quickly pulled out from the loading tube 312. Specifically, the fixing protrusion 323 of the clamp 32 holding the sample is aligned with the clamp assembly groove 3121 arranged in an annular shape inside the loading tube 312. Then, the clamp 32 is pushed into the bottom of the loading tube 312. In this embodiment, the total height of the fixing protrusion 323 and the positioning post 324 is not greater than the height of the positioning cavity 3122 provided at the end of the loading tube 312 near the loading disk body 311. That is, the fixing protrusion 323 and the positioning post 324 can rotate in the positioning cavity 3122. By rotating the clamp 32, the positioning post 324 is slid into the positioning hole 3123 of the loading tube 312, thereby achieving the fixed assembly of the clamp 32.

In this embodiment, the inclined plate 781 of the third collection box 78 facilitates the discharge of solid particles through the filter residue channel 782.

[0032] The application principle of the fretting wear device in a water vapor environment according to an exemplary embodiment of the present invention is as follows: The test specimen is held by clamp 32 and assembled in clamp loading plate 31. The wear module 4 is adjusted to be directly below the multi-load clamping module 3 by activating the second cylinder 51. The position of the multi-load clamping module 3 in the vertical direction is adjusted by the first cylinder 22 to meet the processing requirements. Simultaneously, the feed pump 62 and circulation pump 74 are activated. The feed pump 62 feeds the test water in the material tank 61 into the clamp loading plate 31 through the second material pipe 64, the liquid distribution plate 65 and the third material pipe 66, and then into the annular fluid channel 3112 through the first radial fluid channel 3113, and into the loading pipe 312 through the second radial fluid channel 3114, acting on the specimen held by clamp 32. Then, the first motor 24 and the second motor 41 are activated simultaneously to start the water vapor environment fretting wear on the specimen. In this embodiment, the wear rate of the specimen can be controlled by controlling the rotation speed of the first motor 24 and the second motor 41 to achieve wear on multiple specimens. It should be noted that in one exemplary application scenario, when the multi-load clamping module 3 is adjusted to the processing position, the first motor 24 can be turned off and the second motor 41 can be turned on to test a single sample clamped by the multi-load clamping module 3. In another exemplary application scenario, the second cylinder 51 can be turned on simultaneously with the first motor 24 and the second motor 41, causing the wear module 4 to reciprocate linearly under the action of the auxiliary drive module 5, thereby realizing the wear module 4 to perform linear and circumferential composite wear on the sample clamped by the multi-load clamping module 3. The test water and the solids generated by wear can form a mixed fluid, which is filtered, separated and circulated by the circulation filter module 7, so that the solid particles are discharged and the liquid flows back to the water vapor supply module. It should be noted that the water vapor environment micro-motion wear device of this embodiment has the characteristics of high efficiency, accuracy and versatility, and is especially suitable for online linkage and batch testing scenarios.

[0033] The water vapor environment micro-motion wear device of this embodiment achieves rapid clamping of multiple samples in a water vapor environment through the multi-load clamping module 3. The main drive module 2, wear module 4 and auxiliary drive module 5 are set to achieve linear and circumferential composite wear, which is suitable for a variety of test scenarios.
