AI Technical Summary
Existing pressure gauge sealing detection devices cannot accurately locate minute leaks, cannot simulate different temperature conditions, resulting in low detection accuracy and unsuitability for high-temperature and high-pressure environments. Furthermore, existing devices cannot adapt to pressure gauges of different specifications.
It employs a pressure storage buffer tank, quick connectors, infrared thermal sensors, gas source components, and a PLC controller module, combined with heating and cooling components, to detect the sealing performance of pressure instruments through gas pressurization and infrared thermal imaging technology, adapting to pressure instruments of different temperatures and specifications.
It enables precise testing of the sealing performance of pressure instruments, can simulate actual working conditions at different temperatures, adapts to pressure instruments of different specifications, improves testing accuracy and efficiency, and avoids damage to the instruments by liquid media.
