And the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic pipe production, in particular to a hydraulic pipe air tightness detection device and an operation method thereof. Background technique [0002] At present, in the process of hydraulic pipe processing, hydraulic pipes with cracks, micro-holes and other damages are mixed into qualified products because they are not easily recognized by the naked eye of operators, resulting in a decrease in the qualified rate of hydraulic pipes. The existing hydraulic pipes are mostly tested with water The air pressure detection device is used for air pressure detection. For example, the patent with the application number of 201821254236.8 discloses a hydraulic pipe air tightness detection device, which solves the problem that the surface of the hydraulic pipe is wet after the detection. During the testing process, the sealing performance is poor, multiple hydraulic pipes cannot be tested at the same time, and the...
