Abstract

Today, pneumatic equipment is increasingly used for automation in various industrial field. Therefore net work of air pipelines to send compressed air that is made by compressor are stretch around factory and compressed air is supplied to pneumatic equipment within each machines. Diameter of pipe in the network of pipeline is designed to reduce a pressure drop, however fluctuation of flow rate changes is not considered in case numerous machines are operated. Besides in case new machine is set up and operated and change of design.Therefore it is necessary to exactly know pressure change of each points in network of air pipelines.In this paper, we establish network of air pipelines models which are containing receiver, valves and branches, and makes dynamical performance analysis. Air pipelines model treats as distribution parameters, this paper simulates pressure change of each points in network of air pipelines, and compares the experimental results with its simulated results and calculation results of Equivalent Effective Area Method, besides confirms usefulness of its simulation.
