摘要
本文通过分析新华XHA600E直线加速器的常见故障,探讨维护方法。我院使用的新华直线加速器遇到钨门HWFA故障和FLOW联锁故障,无法正常使用。通过观察加速器故障现象,翻阅图纸,分析其发生原因,进行针对性的维修。对于钨门运动这类问题,需要记录钨门位置的电位器供电电压、排除编码器故障,对于加速器FLOW问题,则需要排除加速器冷却循环水水质问题或冷却水管道内壁相关故障。
This paper aims to discuss maintenance methods of Xinhua XHA600E linear accelerator by analyzing normal faults of this machine.The Xinhua XHA600E linear accelerator in our hospital encountered tungsten door HWFA and FLOW interlock,and could not be used normally.Maintenance person implemented targeted maintenance by watching failure phenomenon,reading device drawing and analyzing failure reasons.It’s necessary to record potentiometer supply voltage of tungsten door and exclude encoder failure for problem of tungsten gate movement,and it’s necessary to exclude quality problem of cooling circulating water and inner wall of cooling water pipe.
