Problems solved by technology

Due to the fact that the test is carried out in a specific sand and dust atmosphere, whether it is a power system driven by a motor or a power system driven by a hydraulic pressure, there are problems that are prone to equipment failure, making it difficult to continue the test
[0006] More importantly, none of the existing friction and wear test devices can realize the stable and flexible sand and dust environment-friction and wear test in a low-cost and easy-to-control manner under loading, let alone the sand and dust environment-friction and wear test. Real-time switching between waveform loading and linear loading during the test
[0007] In addition, after the friction and wear test is carried out in the sandblasting atmosphere using the existing method, it often takes half an hour or even longer to clean the test device and its surrounding areas, otherwise, the test device will easily fail when it is turned on after a few days of inactivity

Embodiment 1

[0044] like Figure 1 to Figure 8 As shown, a sand-dust environment-friction and wear dynamic test device includes a box that can be completely closed, a power system and a sandblasting system arranged in the box, the power system is connected to a friction and wear component, and the upper part of the friction and wear component is connected to a loading system, There is a sand return system below the friction and wear components; the inner cavity of the box is divided into four independent closed spaces by a partition plate, the loading system is set in the upper space, the friction and wear components are set in the middle space, and the sand return system is set in the lower space , the dust collection system 61 is arranged in the side space, and the dust collection system 61 communicates with the central space. like Figure 8 As shown in the figure, the box is made by combining the library plate and the frame, the outside is the library plate, the inside is the frame, th...

Embodiment 2

[0060] A kind of sand and dust environment-friction and wear dynamic test device, with reference to embodiment 1, the main difference between it and embodiment 1 is embodied in software, specifically, the processor of the computer control device implements the following steps / functions when executing the program:

[0061] S1, control the servo motor 13 of the loading system to run in the forward direction, and control the servo motor 13 to stop when the loading force fed back by the pressure sensor 20 reaches the preset value;

[0062] S2, controlling the drive motor (ie the servo motor 71 ) of the power system to rotate at a preset rotational speed, thereby driving the sliding seat 32 and the lower clamp 33 to reciprocate at a preset frequency in the horizontal direction;

[0063] S3, control the servo motor 13 of the loading system to run alternately forward and reverse according to the preset frequency;

[0064] S4, control the sand blasting system and the dust collection s...

Abstract

The invention provides a sand dust environment-frictional wear dynamic test device. The sand dust environment-frictional wear dynamic test device comprises a power system and a sand blasting system which are arranged in a box body, the power system is connected with a frictional wear assembly, the frictional wear assembly is connected with a loading system, and a sand returning system is arranged below the frictional wear assembly; an inner cavity of the box body is divided into four mutually independent closed spaces by partition plates, the loading system is arranged in the upper space, the friction and wear assembly is arranged in the middle space, the sand sweeping system is arranged in the lower space, the dust collection system is arranged in the side space, and the dust collection system is communicated with the middle space. Not only can the sand dust environment-friction wear test be stably and flexibly carried out in a low-cost and easy-to-control manner in a loading state, but also the real-time switching of waveform loading and linear loading in the sand dust environment-friction wear test process can be realized; and high-frequency axial tremor and radial offset of the loading rod in the test process can be self-adapted and eliminated, and stable, smooth and flexible operation of the loading system and core components thereof can be ensured.

Description

technical field [0001] The invention belongs to sand-dust environment accelerated test equipment, and specifically relates to a sand-dust environment-friction and wear dynamic test device, which is used for carrying out sand-dust environment-friction and wear dynamic tests on high-end equipment and core components on the apparatus. Background technique [0002] Existing document CN207169760U discloses a new type of sand and dust test box, including a closed test box body provided with an observation window, a blast device for controlling the air circulation in the test box, and a sand blasting device that communicates the blast device and the test box body. The device, the sand and dust recovery device and the control system are arranged below the test box and connected with it, and the sand and dust suction device is provided at the end of the pipeline of the sand and dust recovery device. However, this kind of sand and dust test chamber cannot be used to carry out friction...
