Description

Technical Field

[0001] The present application relates to the technical field of X-ray tubes, and in particular to an X-ray tube testing device. Background Art

[0002] An X-ray tube is a vacuum diode operating at high voltage. It consists of two electrodes: a filament that emits electrons, serving as the cathode, and a target that receives electron bombardment, serving as the anode. Both electrodes are sealed within a high-vacuum glass or ceramic envelope. Due to differences in manufacturing processes and techniques among X-ray tube manufacturers, the quality of X-ray tubes on the market varies greatly. The quality of X-ray tubes directly affects the ultimate image clarity of the X-ray source. Therefore, testing equipment is required to verify X-ray tube performance.

[0003] Patent number CN220933092U discloses an X-ray tube test device. The device comprises a housing, a voltage-carrying structure, connecting cables, a controller, and host computer software. The housing is connected to the voltage-carrying structure at one end and to the controller at the other. The device is controlled by the host computer software. The device boasts high active power, excellent withstand voltage insulation, and a wide beam voltage and current range. Parameters such as beam voltage and current can be adjusted freely, ranging from 80kV to 300kV and 0.8mA to 3mA. Test parameters such as time and pressure can be adjusted based on the type of X-ray tube, making it highly flexible. Test data is stored in real time and automatically saved after the test is completed. The device provides excellent X-ray shielding, providing a robust performance testing environment for various X-ray tube types. The device is easy for operators to use during X-ray source production, avoiding the need for a single X-ray tube performance test device. However, while the oil tray prevents oil from dripping onto the ground and contaminating the environment, it limits the test device's range of motion. Furthermore, oil easily adheres to the universal wheel surfaces, requiring regular cleaning, increasing the device's maintenance costs. Utility Model Content
