故障现象X线普通摄影工作正常,选择X线滤线摄影时,X线机不曝光。故障分析与检修根据故障现象分析X线机普通摄影曝光正常说明X线机高压线路、X线球管及电源控制电路无故障,很可能与滤线栅电路有关。根据滤线栅工作原理当按下摄影手闸至I挡时,滤线栅得电工作吸合,X线球管灯丝增温,同时旋转阳极启动;当操作面板上Ready灯亮时,按动摄影手闸至Ⅱ挡时,则滤线栅断电自由起振的同时,随之产
Symptoms X-ray normal photography work is normal, choose X-ray filter photography, X-ray machine is not exposed. Fault Analysis and Troubleshooting X-ray machine according to the normal phenomenon of normal photographic exposure normal description X-ray machine high-voltage lines, X-ray tube and power control circuit fault-free, probably with the grid circuit. According to the working principle of the grid When pressing the photo gate to I block, the grid is energized to work, the X-ray tube filament heating, while rotating the anode start; when the Ready light on the control panel, press the photography Hand brake to block Ⅱ, then the grid power-off start-up free, along with production
