Description
technical field [0001] The invention relates to the technical field of detection of fluid delivery pipelines, in particular to an airtightness detection system and detection method for complex fluid pipelines based on a bubbling method. Background technique [0002] In the fields of aerospace, automobiles, ships, etc., due to the long-term operation of the fluid pipeline system in harsh environments such as high temperature, high pressure, and severe vibration, safety accidents caused by pipeline leakage and rupture occur frequently. In order to ensure the working reliability of the fluid pipeline, its quality reliability must be tested before it is put into use. With the development of fluid limit technology, the compactness of fluid machinery is getting higher and higher, which leads to the development of the fluid pipeline involved in the direction of high distortion, variable cross-section, complex configuration, and micro-scale. This brings technical difficulties to ai...
