Therefore, airtightness is a core indicator for ensuring safe operation. Traditional airtightness detection methods have the following technical limitations: technicians cannot quickly locate minute leaks manually, and the high cost of infrared detection equipment affects the test results of the pressure vessel's sealing performance.
