医用回旋加速器的靶压故障分析排除
|
摘要
本文旨在解决回旋加速器靶压故障,保障机器正常运行。本文通过对回旋加速器原理分析和电路分析,并仔细阅读回旋加速器的电路图纸,对靶压故障进行逐项分析排查。结果发现继电器4脚和8脚是断路,因而最终确定故障之所在,更换新的继电器,成功解决回旋加速器靶压故障,机器正常运行。像回旋加速器这样的大型设备,只有熟悉其基本原理才能快速解决,保障设备正常运转,更好的为临床服务。
This research aimed to solve the problem of cyclotron target pressure, so as to ensure the normal operation of the machine. Through the analysis of cyclotron principle and circuit analysis, and carefully reading the circuit drawings of cyclotron, the target pressure fault was analyzed one by one. It was found that the 4 feet and 8 feet of the relay were broken, so that the fault was determined. Then, a new relay was replaced, the target pressure failure of the cyclotron was successfully solved and the machine run normally. Large equipments, such as the cyclotron, can only be solved quickly if the maintenance man are familiar with their basic principles. So that they can ensure the normal operation of the equipment and provide better clinical services.
