Description

technical field [0001] The invention relates to the technical field of hydrogen leak detection in hydrogenation stations, in particular to a leak detection platform for hydrogenation equipment and a leak detection method thereof. Background technique [0002] Sealing performance is one of the most important detection indicators for hydrogen refueling station equipment, which is directly related to the safety and reliability of the entire hydrogen refueling station. [0003] Among the existing technologies, most of the sealing performance testing of hydrogenation station equipment leaves the factory by relying on the "soap bubble method" for testing, that is, applying leak detection fluid at potential leak points of the equipment. When leakage occurs, the leak detection fluid can be observed to produce The "bubble" of the device can be used to qualitatively judge whether there is leakage in the equipment. Moreover, the "soap bubble method" needs to manually apply leak detect...
