Description

technical field [0001] The present invention relates to a test system and method for studying the ignition of sulfur under friction conditions, specifically, a sulfur friction behavior research test system and its test method, which can monitor the sulfur friction behavior in a relatively closed environment. During the process, the temperature near the surface of the friction surface, the change of friction force, the amount of wear of the sample and the gas generated. Background technique [0002] Sulfur is an important chemical raw material, flammable and explosive. Its combustion product sulfur dioxide has great harm to human health and the environment. In the process of sulfur production, storage and transportation, there are many friction pairs, and sulfur will catch fire under the action of friction pairs. However, this phenomenon has been ignored by people all the time. What is the mechanism of sulfur burning under frictional conditions, what are the factors that af...

Problems solved by technology

[0003] However, due to the limitations of the equipment itself, the relevant test equipment for researching sulfur friction ignition requires manual operation of the ratio, and is not equipped with an exhaust gas absorption module. After the test, toxic and harmful gases will still be released into the atmosphere; only a The air inlet shared with the feeding mechanism does not involve the air supply device, and the influence of the speed of the supply air on the heat dissipation of the test equipment is unknown, which seriously affects the research on the frictional ignition behavior of sulfur
