Abstract
This paper presents an alternative method for obtaining the flow rate characteristics of all types of pneumatic components. The proposed method determines flow rate characteristics by measuring pressure response in an Isothermal Chamber during discharge into the atmosphere. Expansive flow rate expression is used to satisfy various pneumatic components including valve, silencer, speed controller, etc. The paper also establishes a practical calculation technique for flow rate characteristics. Measurement results show the effectiveness of the proposed method. In addition, the proposed method is able to achieve a shorter measurement time and less air consumption than the ISO discharge method. The proposed method has the same precision as the ISO discharge method but it offers higher productivity.
