Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing of workpieces, in particular to liquid penetration equipment for non-destructive testing of workpieces. Background Art

[0002] A surface non-destructive testing method, which mainly involves immersing the workpiece being tested in a penetrant with high penetration ability. Due to the wetting effect and capillary phenomenon of the liquid, the penetrant penetrates into the open defects on the surface of the solid material, and then the infiltrated penetrant is precipitated to the surface through a developer, thereby achieving the purpose of non-destructive testing.

[0003] In the Chinese utility model patent application disclosure CN218121796U, a liquid penetration device for non-destructive testing of workpieces is disclosed. The liquid penetration device for non-destructive testing of workpieces includes an immersion box and a drain plate. The immersion box is used to hold the permeate. The top of the immersion box is provided with an opening for the workpiece to be placed in or taken out. The drain plate is arranged on the immersion box near the opening. The drain plate can be inserted into the immersion box or pulled out from the immersion box. The drain plate inserted into the immersion box can be placed on the workpiece after immersion for draining. The present application can set the drain plate to be retractable. When the workpiece to be immersed is placed in the immersion box, the drain plate can be pulled out, thereby providing a larger avoidance space for the workpiece to pass through. Compared with the fixed drain plate, the size range of the workpiece that can be operated by the liquid penetration device provided by the present application is larger, the application range is wider, and the practicality is higher. However, the device operates the workpiece to be immersed at a fixed angle. For some workpieces, there will be air pressure in the inner cavity, which will cause the solution to not enter, resulting in incorrect detection results. For this reason, we propose a liquid penetration device for non-destructive testing of workpieces. Utility Model Content
