SHENYANG ZIWEIHENG TESTING EQUIPMENT CO.,LTD

?Test items? Gas Thermal Cycling Test Machine is a special testing machine developed for GMW14191-2010, which can realize high temperature, normal temperature and pressure temperature shock test of medium gas. ?Technical parameters? Number of test cycles: 3000 cycles Compressed air temperature: 49±0.5°C Intake air pressure: 100 ± 5kPa Frequency: 0.083HZ (12 cycles/hour) ?Test methods? Test method 1: The temperature of the intake air is raised from 49 ± 0.5°C to 160 ± 5°C in 1 minute and maintain at 160 ± 5°C for two minutes. After that, the temperature is lowered from 160 ± 5°C to 49 ± 0.5°C in 1 minute, and maintain at 49 ± 0.5°C for 1 minute, and the leakage is automatically judged. Test method 2: The temperature of the intake air is raised from 49 ± 0.5°C to 200 ± 5°C in 1 minute and maintain at 200 ± 5°C for two minutes. After that, the temperature is lowered from 200 ± 5°C to 49 ± 0.5°C in 1 minute, and maintain at 49 ± 0.5°C for 1 minute, and the leakage is automatically judged.
