Using the detailed process that the leakage detection apparatus of the present embodiment carry out high efficiency leak detection it is:
Step one, the size according to the in part 6 to be checked first port 61 to be checked and the second port 62 to be checked, select corresponding chi Very little active joint 44 and integrated adaptor 4, active joint 44, first leak detection unit and the second leak detection unit are quickly assembled in On integrated adaptor 4.
Step 2, by the first fast joint 11, the second fast joint 12 quick by first hunt leak unit, the second leak detection unit with Helium filling retracting device is connected, and the first port to be checked by active joint 44, anchor tip 45 corresponding insertion part 6 to be checked 61 and second in port 62 to be checked, is screwed into the first fixing hole 43 by fixing bolt 5, in the second fixing hole 63, by integrated switching 4 are fixed on part 6 to be checked, form whole car air-conditioner leak detection system.
Step 3, block helium fill retracting device and second leak detection unit between path, control helium filling reclaim Helium is noted in the pipeline connecting with the first port 61 to be checked by device, and cooperation helium mass spectrometer leak detector detects whether described pipeline is let out Leakage, controls helium filling retracting device by helium recovery after the completion of detection.
Step 4, block helium fill retracting device and first leak detection unit between path, control helium filling reclaim Helium is noted in the pipeline connecting with the second port 62 to be checked by device, and cooperation helium mass spectrometer leak detector detects whether described pipeline is let out Leakage, after the completion of detection, integrated adaptor 4 is dismantled by control helium filling retracting device by helium recovery, rather loose fixing bolt 5.
Step 5, repeat step one to four detect to port subsequently to be checked.
The car air-conditioner leakage detection apparatus of a kind of high detection efficiency described in embodiment 1 and method, structure is simple, versatility By force, two groups of leak detection units are become one it is achieved that once detect the purpose of two-way pipeline simultaneously, detection efficiency is high, is easy to Popularization and application.
Below schematically the present invention and embodiments thereof are described, this description does not have restricted, institute in accompanying drawing Show is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area Art personnel enlightened by it, in the case of without departing from the invention objective, designs and this technical scheme without creative Similar frame mode and embodiment, all should belong to protection scope of the present invention.
