Leak detection in the nuclear power industry
Application of nuclear fuel rod sealing performance testing.
Using vacuum helium mass spectrometry analysis method, the whole fuel rod is leaked.
Main performance characteristics
1. Automatic leak detection without manual intervention;
2, the accuracy of leak detection is extremely high;
3, with data recording analysis, remote monitoring functions;
Fluorinated Oil Leak Deteciton Device
Helium fluorine oil pressurized leak detection device is a set of automatic leak detection device for the detailed and rough inspection of semiconductor devices, integrated circuits, electronic products and other electronic components. It can be used in conjunction with a helium mass spectrometer leak detector and a heavy fluorine oil heater to perform the entire fine inspection and rough inspection process of electronic components.
1. Helium pressurization fine inspection of components
First put the components in a pressurized sealed container. If the components leak, helium will be pressed into the cavity. After the components are taken out, they are put into a vacuum container, and the helium quality is used for leak detection.
2. Fluorine oil coarse leak detection of components
Put the components under inspection into a pressure vessel, inject low-boiling fluorine oil, submerge the workpiece, and pressurize it for a certain period of time. After the pressurization is complete, take out the test piece, and then immerse it in the heated heavy fluorine oil to observe the bubbles. If bubbles are found, it can be judged as unqualified.
