Abstract
Description
technical field
[0001] The invention relates to the field of bellows airtightness detection, in particular to an airtightness detection system. Background technique
[0002] Bellows are commonly used elastic elements. Such as figure 1 As shown, the entire pipe body is composed of several crests 12 connected end to end, and notches 11 are respectively provided at both ends of the corrugated pipe 1 in the length direction. The seam 11 is used to connect with other components.
[0003] The corrugated pipe 1 is usually used for the transportation of fluids. Therefore, after the corrugated pipe 1 is actually produced, it is necessary to perform an airtightness test on the corrugated pipe 1 . Qualified products that pass the test can be sold and used.
[0004] The airtightness test of bellows often adopts "color difference method".
[0005] The specific steps of the color difference method are as follows:
[0006] First, the staff seals one end of the corrugated pipe to be t...
