Abstract
The present invention relates to the field of CT tube core exhaust technology, and in particular to an exhaust device and exhaust process for a CT tube core with a full metal shell. The exhaust device of the present invention comprises a tube core exhaust platform, a sealing bottom plate is provided on the tube core exhaust platform, a support structure is provided on the sealing bottom plate, a CT tube core with a full metal shell is fixed horizontally on the support structure, and a vacuum exhaust pipeline assembly is connected to the exhaust port of the CT tube core with a full metal shell; an oven is provided directly above the sealing bottom plate, and the oven and the sealing bottom plate can be in sealed contact. The exhaust process of the present invention comprises the steps of tube installation, vacuum baking degassing, and high-pressure target practice degassing. The present invention can achieve efficient exhaust of the CT tube core with a full metal shell liquid metal bearing. During the exhaust process, the gas adsorbed in the tube is fully released and promptly extracted from the tube by vacuum heating and high-pressure target practice.
