【摘要】:分析了在液压缸活塞端部加工变形唇边实现压力补偿自适应变间隙密封的密封机理,并基于ANSYS有限元仿真软件对活塞唇边不同受载情况下的变形规律进行了仿真分析。设计了以高精度压力变送器和流量计进行压力和流量实时监测,以Lab VIEW编程和数据采集卡进行数据实时采集、处理并记录的液压缸内泄漏量测试系统。结果表明测试稳定可靠,验证了在活塞端部采用唇边式压力补偿自适应变间隙密封结构是解决当前常规恒间隙密封液压缸内泄漏量大的可行有效的办法。
[Abstract]:This paper analyzes the sealing mechanism of the pressure compensated adaptive variable clearance seal by machining the deformed lip at the end of the piston of the hydraulic cylinder. Based on the ANSYS finite element simulation software, the deformation law of the piston lip under different loads is simulated and analyzed. A high precision pressure transmitter and Flowmeter are designed for real-time monitoring of pressure and flow, and Lab VIEW programming and data acquisition card are used for real-time data acquisition, processing and recording. The results show that the test is stable and reliable, and it is proved that the lip pressure compensation adaptive variable clearance seal structure is a feasible and effective method to solve the large leakage in the hydraulic cylinder of the conventional constant clearance seal at present.
