The invention discloses an air tightness detection system, which is characterized in that the system comprises a parameter acquisition and control platform and an air tightness big data processing subsystem, and the system realizes air tightness parameter detection, processing and air tightness grade classification of a detected object. The system is advantaged in that due to problems of low efficiency, inaccuracy and the like of the existing air tightness detection technology, influence on the performance of the building and the mechanical product is caused by imperfect air tightness detection on the building and the mechanical product, an air tightness detection problem of the existing building and the mechanical product is effectively solved.
Description
technical field [0001] The invention relates to the technical field of airtightness detection automation equipment, in particular to an airtightness detection system. Background technique [0002] With the development of industrial technology, the requirements for air tightness in construction, machinery, aerospace vehicles, air conditioners and gas appliances are getting higher and higher. Air tightness testing is one of the important means to ensure the quality and safety performance of construction and mechanical products. First, the detection of air tightness is gradually required to be intelligent, and it is required to be applicable to online detection. Among the air tightness detection methods, the traditional "wet method", pressure drop method and flow measurement method have low detection accuracy, and these methods are not suitable for mass production inspection of building and mechanical seals. The differential pressure method is widely used in the air tightness ...
