摘要
以某煤矿的气动工具为研究对象,基于井下潮湿环境易导致气动工具密封结构失效的问题,分析高压差作用下材料力学响应、密封间隙对失效风险的定量影响等,以明确气动工具密封结构失效机制。随后提出了气动工具密封结构改进技术,包括密封材料性能强化技术、密封结构参数优化技术等,并开展实验环境模拟,进行压力保持性能测试等,以保障密封结构在高湿环境下稳定运行,增强气动工具的安全可靠性。
Taking pneumatic tools in a coal mine as the research object,based on the problem that the sealing structure of pneumatic tools are easy to fail in the underground humid environment,this paper analyzes the mechanical response of the material under the action of high pressure difference,the quantitative influence of the sealing gap on the failure risk,etc.,to clarify the failure mechanisms of the sealing structure of pneumatic tools.Then,the improvement technologies for the sealing structure of pneumatic tools are proposed,including sealing material performance enhancement technology,sealing structure parameter optimization technology,etc.,and the experimental environment simulation and pressure retention performance test are carried out,so as to ensure the stable operation of the sealing structure in high humidity environment and enhance the safety and reliability of pneumatic tools.
