Example Embodiment

[0036] Example one,

[0037] Such as Figure 1-3 As shown, an ultra-high frequency X-ray flaw detector and control system includes a casing 1, one end of the casing 1 is provided with a first heat dissipation fan 3, the first heat dissipation fan 3 uses a blowing method to dissipate heat, and the other end of the casing 1 A refrigeration device 5 is provided. The refrigeration device 5 is a detachable mechanism and is bolted to the casing 1. The outside of the first heat dissipation fan 3 and the end of the refrigeration device 5 are both provided with a heat dissipation hood 104, which connects the two parts of the entire device The beryllium sheet window 101 is provided on the casing 1, and the beryllium sheet window 101 is provided with a filter window protection plate. The beryllium sheet window 101 is provided with a beryllium sheet for filtering radiation, thereby reducing scattering The beryllium sheet window 101 is provided with a laser sensor 2 on one side of the window...

Example Embodiment

[0050] Example two,

[0051] In order to further improve the working efficiency of the equipment, in this embodiment, the ray tube 6 adopts a rotating target ray tube. The rotating target ray tube is fixed and limited in the radial direction through a fixed sleeve, and a positioning bolt is arranged on the casing 1 to axially limit the rotating target ray tube to ensure the reliability of use. The rotating target ray tube is driven by a rotating motor.

[0052] Compared with the first embodiment, the rotating target ray tube is used in this embodiment. Compared with the fixed target ray tube, the cooling effect is better, and the working efficiency is better. It avoids the fixed target ray tube with fixed working point, which is caused by high temperature after long-term irradiation. The breakdown problem increases the reliability of the equipment.

[0053] In addition, such as Image 6 As shown, the control system of the UHF X-ray flaw detector includes J1900 embedded logic board, ...

Description

technical field [0001] The invention relates to the technical field of X-ray flaw detectors, in particular to an ultra-high frequency X-ray flaw detector. Background technique [0002] Industrial X-ray flaw detector, including the X-ray tube head assembly, control box and connecting cables, is a general term for X-ray photography or tomographic inspection of the internal structure of objects. [0003] X-ray flaw detector is specially used for shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction and other industrial sectors to check the welding quality of materials and parts such as ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles and bridges, as well as various light metals. , rubber, ceramics and other processed parts quality. Using the method of X-ray transillumination photography, the internal defects of the parts processed by the material and the welding are displayed from the X-ray film to evaluate t...
