Development of new test bench for vacuum ejector and vacuum regulator based on ISO standard

Abstract

In this paper, we developed two new test benches for vacuum ejector and vacuum regulator, which based on ISO standards, are suited for the current status of the domestic production of vacuum components. These benches have a simple structure, can be used easily and are designed with a more reasonable circuit. The high-response flow transducer used in the circuit was designed on pneumatic power to make the result more accurate. The bench, not only provides a new platform for characteristic testing of vacuum components, but also greatly facilitates the standardization of the production of vacuum components. © 2012 Springer Science+Business Media B.V.
