Abstract
The invention provides a vacuum pressure fluorescence penetration detection process, and relates to the technical field of fluorescence penetration detection. Before immersing in the infiltration liquid, the workpiece is sealed in a vacuum pressurizing infiltration tank, the gas in the surface opening defect of the workpiece to be detected is discharged through vacuumizing, and then the whole workpiece is immersed in the infiltration liquid. Finally, by pressurizing the permeate tank, the amount of permeate entering the open defects is increased. In the development stage, the workpiece with the surface permeate liquid removed is placed in a sealed development tank, the vacuum is pumped to the development tank to force the permeate liquid in the opening defect to be sucked out, and then development powder is applied to display the surface opening defect. The invention increases the work vibration technology in the development stage, which is beneficial to the massive seepage of the seepage liquid in the opening defect.

Compared with the prior art, the invention seals the workpiece in the vacuum pressurizing infiltration tank before immersing in infiltration liquid, discharges the gas in the opening defect through vacuumizing, and then immerses the whole workpiece in the infiltration liquid. The amount of permeate entering the open defects is then increased by pressurizing the permeate tank. In the development stage, the workpiece with the permeate liquid removed is placed in a development tank, the vacuum is pumped to the development tank to force the permeate in the opening defect to be sucked out, and then development powder is applied to display the defect. The invention increases the work vibration process in the development stage, which is beneficial to the permeation and massive exudation in the opening defect.
