CHARACTERISTICS MEASUREMENT OF PNEUMATIC ELEMENTS USING ISOTHERMAL CHAMBER

Kenji Kawashima; Toshinori Fujita; Toshiharu Kagawa; Jiseong Jang

In this study, methods for the characteristics measurement of pneumatic elements using isothermal chamber, the methods for the flow rate and dynamic characteristic measurement of pneumatic control valve, are proposed. An isothermal chamber is a chamber in which the steel wool is stuffed and isothermal condition can almost be realized. Therefore, the instantaneous flow rate could be measured only from the pressure response using the state equation of gas. Effectiveness and simplicity of the proposed method are confirmed by comparing the measured results obtained by proposed methods with the methods defined JIS and the ISO standards.
