Energy-saving Optimization Study of Direct Pressure Airtightness Testing System
摘要
Abstract
Airtightness testing is a crucial technical measure to ensure the specific pressure chambers sealing performance.The direct pressure testing method is widely adopted in the manufacturing of such chambers due to its simple principle and convenient operation.However,its energy consumption issues have not received sufficient attention.To address energy waste caused by direct emission of compressed air after single-use in conventional direct pressure testing,a detection gas recovery and reuse method based on recycle air tanks is proposed,aiming to design an energy-saving direct pressure testing system that integrates high-precision detection and one-click start-stop functionality.A human-machine interface is developed via programming software to achieve solenoid valve switching control and real-time pressure monitoring during testing.The results demonstrate that the gas recovery and reuse scheme significantly reduces compressed air consumption,achieving a 16.2%reduction in energy consumption per test,which provides theoretical foundations and engineering references for energy optimization in direct pressure airtightness testing.关键词
