Description

Technical Field

[0001] The utility model relates to the technical field of through-flow boilers, in particular to a through-flow boiler surface opening penetration detection device. Background Art

[0002] Tubular boilers are widely used in industrial production due to their high efficiency, energy efficiency, and compact structure. They achieve rapid heating of fluids and continuous heat supply through heat exchangers. However, to ensure their safety and reliability during operation, tubular boilers must undergo nondestructive testing after production. This testing can identify and assess potential surface defects, such as microcracks and pores, without destroying the boiler, thereby preventing potential safety hazards.

[0003] Penetrant testing is a commonly used nondestructive testing method for through-flow boilers. This method allows a penetrant liquid to penetrate open defects on the material surface for accurate inspection. Currently, spraying is mostly done using spray cans containing liquid penetrant. However, due to the limited capacity of spray cans, when multiple boilers need to be inspected, a single spray can may be used up before spraying is completed. Furthermore, inconsistent liquid penetrants when changing spray cans can affect inspection accuracy. After spraying, the penetrant must be allowed to dwell for an appropriate amount of time before any excess is removed using water, solvents, or emulsifiers. This process is performed under ultraviolet light to ensure that all excess penetrant is completely removed. Finally, a developer is applied, and a specific light source is used to visualize defects.

[0004] The current market lacks a penetrant inspection device that can integrate these steps. Developing a device with centralized functionality can effectively address issues with spray tank capacity and penetrant consistency, while also optimizing the penetrant removal and imaging processes. This will significantly improve the inspection efficiency and accuracy of through-flow boilers. To this end, we propose a penetrant inspection device for through-flow boiler surface openings.
