对如何延长石油工程施工中常用的无损检测设备X射线探伤机的使用寿命问题进行了探讨。调查分析了施工现场的X射线机使用状况, 并对影响使用寿命的原因进行了细致分析, 通过现场验证、测量等方法确定了三个主要的原因: 操作人员违反工艺规程, 不训机; 设备连续工作时间长; 工况差, 设备运输时受到振动。针对这些主要原因, 制定了具体措施来延长X射线机的使用寿命, 取得了良好的效果, 使用寿命均超过额定寿命。

The title mainly discusses how to delay the service life of X-ray detectors which are used in petroleum engineering construction. We investigated the service life of X-ray detector in construction site and carefully analyzed the causes. Three main causes that are violating process, long time working, vibrating in transportation, have been found by the methods of verification and measurement etc. Some specific measures for these causes have been made to delay the service life of X-ray detectors. They achieved good effect, all detectors’ service life exceeded rated life.
