Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aging test equipment, and particularly relates to a rotary CT tube aging device and an aging method. BACKGROUND

[0002] In a CT device, a tube is a core component for generating X-rays. When the tube is working, the anode needs to rotate at a high speed to generate X-rays. In order to ensure that the tube has good performance, at present, the tube is aged by a tube aging device.

[0003] The existing tube aging device is a static fixed device. In the aging process, the tube anode needs to rotate at a high speed to generate X-rays, and the tube body is in a fixed manner and is stationary. During the rotation of the tube anode, the bearing is continuously subjected to friction, and the continuous friction will inevitably cause the wear of the bearing. During the wear process, metal chips of the bearing of metal material will enter the tube core and adhere to the inner wall of the tube core. Due to the limitation of the stationary tube body and the working mode of the tube, it is difficult to clean the metal chips on the inner wall of the tube core.

[0004] When the CT tube is installed on the CT machine and put into actual use, the tube is in a high-speed rotating state, and the metal chips and other impurities on the inner wall of the tube core will fall off and may enter the area with high electric field intensity, causing high-voltage sparking. High-voltage sparking not only causes high temperature instantaneously, damages the insulating materials and other components inside the tube, but also causes unstable operation of the tube, affects the output quality and stability of X-rays, and further seriously affects the imaging effect of the CT machine, and even may cause equipment failure, and cannot provide accurate image information for clinical diagnosis.

[0005] In addition, due to the stationary tube body in the aging process, the natural convection of the test oil in the oil tank is weak, the temperature gradient is large, the heat exchange efficiency is low and uneven, the heat of the tube core cannot be discharged in time, the internal heat is accumulated, the core components are damaged due to over-temperature, and the thermal environment stability of the aging process is affected, and finally the service life of the tube is shortened and the performance of the tube is reduced. SUMMARY

[0006] The present application aims to provide a rotary CT tube aging device and an aging method. In the aging process, the tube rotates rapidly in the oil tank, the centrifugal force generated by the rotation makes the impurities separate from the inner wall of the tube, the impurities are cleaned by the high-voltage sparking assembly, and at the same time, the rotation of the tube can strengthen the convection of the tube and the test oil, and improve the heat exchange efficiency.
