Testing Principles

By evacuating the vacuum chamber, the sample immersed in water is subjected to an internal and external pressure difference, and the gas leakage inside the sample is observed to determine its sealing performance; By evacuating the vacuum chamber to create an internal and external pressure difference in the sample, observing the expansion of the sample and the recovery of its shape after releasing the vacuum, the sealing performance of the sample can be determined
