Description

Technical Field

[0002] In the process of in-depth research on the friction characteristics of mechanical parts, the influence of the gas environment is crucial. By precisely controlling and changing the gas environment, the friction response of parts under different atmospheric conditions can be understood more accurately. The use of inert gases such as nitrogen and argon can effectively prevent oxidation reactions on the surface of the material, which is particularly critical for analyzing the friction behavior of metal parts. In addition, precise environmental control can also help eliminate the interference of impurities and moisture that may exist in the air on the experimental results, ensuring the stability and repeatability of the experimental conditions. By conducting friction studies in a gas environment, the performance of mechanical equipment parts in different working environments can be more comprehensively evaluated, providing scientific and reliable data support for optimizing design and improving engineering practices.

[0003] In friction experiments, the design of the device for controlling the gas environment must be carried out according to the specific experimental needs and conditions. The key lies in the precise control and measurement of various parameters of the gas. The current controllable gas environment devices include gas environment chambers, gas flow control systems, vacuum chambers, and atmosphere control chambers. At present, the gas environment chamber faces several significant problems in practical applications: gas leakage may occur during operation, which may be caused by imperfect sealing or pipeline connection problems, which in turn affects the stability and accuracy of the experimental environment; insufficient gas mixing is another common challenge, sometimes caused by improper mixing chamber design or mechanical problems during the mixing process, which may lead to uneven gas composition in different areas, affecting the reliability and reproducibility of the experimental results; the mixing method of existing gas environment chambers is usually relatively single, which is difficult to meet the needs of multiple gas combinations under complex experimental conditions, limiting its flexibility and applicability in different experimental settings.

[0038] The working principle of the above-mentioned gas environment chamber is:

[0039] Before starting the gas environment chamber, firstly, it is necessary to carefully check each device to ensure that they are operating normally and well connected, including checking the status and function of the heating device 3, humidifying device, sensing device 6 and dynamic sealing film 2; then, gently place the friction test device such as friction pair 7 into the gas environment chamber to ensure that the placement position is appropriate and will not affect the normal operation of other equipment or pipelines; then, use the dynamic sealing film 2 composed of a rubber sleeve to carefully seal the gas environment chamber to ensure that the gas environment in the chamber can be maintained stably. Turn on the sensing device 6 to monitor and record important parameters such as temperature and humidity in the chamber. Subsequently, turn on the air intake device in turn, and start the humidifying and heating device 3 at the same time. These steps need to be adjusted step by step to ensure that the gas composition and conditions in the chamber meet the requirements and settings of the experiment. After the experiment reaches the required predetermined conditions, the formal experimental operation can be started.
