1故障现象按下手闸,旋转阳极工作正常;曝光预备继电器工作正常;曝光继电器SC不能工作;摄片无法进行。2故障分析处理经检查发现曝光时间控制限时器不能工作。本机限时器属老式钟表式限时器,可靠性差,曝光时间精确度不足。我们决定采用JSB-23型半导体限时器来代替。JSB-23半导体?
1 Symptom Press the hand brake, rotating anode is working properly; exposure preparation relay is working properly; exposure relay SC can not work; radiography can not be carried out. 2 Failure Analysis and Processing After the inspection found that the exposure time control timer can not work. The local timer is an old watch timer, poor reliability, exposure time accuracy is not enough. We decided to use the JSB-23 type semiconductor timer instead. JSB-23 semiconductor?
