Description

Technical Field

[0001] The invention relates to the technical field of X-ray tube oiling, in particular to a rapid vacuum cycle oiling system for an X-ray tube. Background Art

[0002] The CT tube is a vacuum component that works under high voltage. It is used in medicine for imaging diagnosis and in industrial technology for non-destructive testing of materials, structural analysis, spectral analysis, and film exposure. It has a wide range of applications. During the operation of the CT tube, a large amount of heat is generated on the anode, which needs to be circulated and removed by insulating oil injected by an oiling machine. Traditional oiling machines use vacuum pumps to create a pressure difference to guide the insulating oil in the oil barrel into the tube sleeve of the CT tube. Such devices are too limited in the scenarios they can be used in. When dealing with other large CT tubes with high heat capacity, incomplete exhaust will occur, and small bubbles will exist, causing tube quality problems. In view of this, vacuuming is required when oiling the X-ray tube.

[0003] Generally, a vacuum system is connected to the oiling machine of the X-ray tube. Before the oiling machine is used to fill the tube with oil, the tube is first vacuumed. After the vacuum is drawn, the tube is circulated and filled with oil through the oiling unit. There are two main problems in the existing technology: first, vacuuming cannot be performed while filling the tube with oil, and the bubbles generated during the filling process affect the vacuum effect in the tube; second, the vacuuming efficiency is low, and a long waiting time is required for each use.
