【摘要】：随着自动化工业的发展,尤其是气动行业的快速发展,气动电磁阀的应用日渐广泛。作为气动系统中重要的一类元件,其动态特性直接影响到整个系统的性能及控制精度,直接反映气动电磁阀动态响应性能的参数是电磁阀的切换时间,本文将对电磁阀切换时间的测试标准进行深入的研究。目前国内外气动行业对电磁阀动态特性——切换时间的测试标准是ISO12238:2001《Pneumatic fluid power—Directional control valves—Measurement of shifting time》,在实际测试中,经常出现的一些亟待解决的问题。本课题通过对标准ISO12238：2001测试内容以及测试方法的深入研究与分析,针对这一系列问题,探究相应的解决方案,并在此基础上搭建了测试系统,经过大量试验研究,对标准作出修正与补充。这对气动电磁阀切换时间的测试工作、测试标准的修正与研究有重要的指导意义。第一章概述了电磁阀的发展历史,引用并分析了大量国内外电磁阀切换时间的测试标准,详细总结了国内外测试标准的现状及发展方向。最后提出了本课题的研究意义及主要研究内容。第二章从气动电磁阀的基本结构及工作原理出发,分析了电磁阀切换时间产生的原因,并详细介绍气动电磁阀切换时间测试标准ISO12238《Pneumatic fluid power—Directional control valves—Measurement of shifting time》的内容。第三章通过对标准ISO12238测试内容与测试方法的深入研究与分析,对标准中需要补充与修正的内容作了详细的理论研究。第四章提出了气动电磁阀切换时间测试系统的设计方案,并分析了系统的硬件设计、电路系统以及软件模块功能的实现等,在此基础上搭建了试验台。第五章对标准中需要补充与修正的内容,进行了相关的试验研究。第六章在前面几章的基础上,对标准进行了系统的修正与补充,并明确了测试气路图、测试条件、测试方法等。第七章对全文的主要研究工作进行了总结,并展望了后续的工作。附录为课题补充修正后的气动电磁阀动态特性——切换时间的测试标准。
[Abstract]:With the development of industrial automation, especially the fast development of pneumatic industry, application of pneumatic solenoid valve is widely. As a kind of important element in pneumatic system, its dynamic characteristics directly affect the performance and control precision of the whole system, directly reflects the dynamic response performance of the gas parameters is the switching time of the electromagnetic valve pneumatic solenoid valves the test standard of solenoid valve switching time for further study.
At present at home and abroad of the electromagnetic valve dynamic characteristics test standard switching time is ISO12238:2001, in the actual test, some problems often arise. Through in-depth study and analysis of the standard ISO12238:2001 test contents and test methods, aiming at this a series of problems, explore the corresponding solutions, and on this basis to build a test system, after a lot of experiments, the amendment and supplement to the standard. The pneumatic test of switching time of the electromagnetic valve, has the important guiding significance of revision and testing standards.
In the first chapter, the development history of solenoid valve is summarized, and a large number of test standards for solenoid valve switching time at home and abroad are cited and analyzed. The status and development trend of test standards at home and abroad are summarized in detail. Finally, the research significance and main research contents of the subject are put forward.
The second chapter from the basic structure and working principle of pneumatic solenoid valve, analyzes the reasons of switching time of the electromagnetic valve is generated, and introduces the pneumatic switching time of the electromagnetic valve testing standard ISO12238.
In the third chapter, through in-depth research and analysis of standard ISO12238 test contents and testing methods, detailed theoretical research is made on the contents that need to be supplemented and corrected in the standard.
The fourth chapter puts forward the design scheme of the pneumatic electromagnetic valve switching time test system, and analyzes the hardware design, the circuit system and the realization of the software module function. Based on that, a test rig is built.
The fifth chapter carries out the related experimental research on the content that needs to be supplemented and amended in the standard.
In the sixth chapter, on the basis of the previous chapters, the standard revision and supplement system, and define the test gas roadmap, test conditions, test methods and so on.
The seventh chapter summarizes the main research work of the full text, and looks forward to the follow-up work.
The appendix is a test standard for the dynamic characteristics of the pneumatic solenoid valve after the supplementary revision of the subject, the switching time.
