Abstract:Objective To make more accurate maintenance positioning, the maintenance method was discussed and maintenance
experience was accumulated by analyzing United Imaging 16 slice CT. Methods The working principle and mutual relation of
the high-voltage bulb tube in 16 slice CT were studied, and the influence of KV power on the cathode and grid was analyzed, so
as to locate the fault phenomenon. Results Through this maintenance, not only the equipment fault was solved, but also had a
deeper understanding of the high voltage devices, which was helpful for future maintenance. Conclusion This article focused on
the relationship between the high pressure and the bulb tube, which affected each other. In judging the fault, we should clarify our
thinking and conduct investigation step by step according to its principle, and carefully verify, and finally determine the fault point to
complete the repair.
