Abstract Pneumatic technology is a rapidly developing and widely used in industrial automation, pneumatic components, flow characteristics of an important technical indicators. Pneumatic control systems and improve product quality pneumatic components model accurate understanding of flow characteristics, China pneumatic industrial development is of great significance. The flow characteristics of pneumatic components and clarifying the meaning and the relationship between them are essential in several ways to facilitate the flow characteristics and significance of understanding the relationship between the conversion parameters. Now the characteristics of the test process and a more traditional testing methods, test efficiency and low precision, therefore, a convenient design, high-precision test system has become an important issue. This article on the above issues, in-depth analysis of pneumatic components flow characteristics, and on this basis, the design flow characteristic test system, using isothermal container flow characteristics of the new test method than the ISO6358 save time and gas by using isothermal container deflated curve to measure pneumatic solenoid valve sonic conductance C and critical pressure ratio b, to further promote the actual process of the isothermal container. Thesis is pided into five chapters: the first chapter introduces the pneumatic flow characteristics test the status quo, and then introduced the flow characteristics of pneumatic components significance test system. The second chapter is the analysis and study of flow characteristics of pneumatic components of several test methods, highlighting the advantages of energy saving isothermal containers. Chapter III describes the flow test system hardware design, component selection. The fourth chapter describes the hardware design flow test system software design, interface design and operation of observation methods. Chapter V is the full text of the summary and outlook , introduced their work and research some of the conclusions and flow characteristics did some prospect.
Keywords: Test system design; Test Guidelines; pneumatic components characteristic flow; flow characteristic parameters
