XG-500mA X 线机发生1起故障。表现为透视正常,而点片、照像均无 X 线发生。为查清故障原因,须检查灯丝加热部分、高压部分及控制系统。结果表明:1.大小焦点加热正常。2.高压部分无初级电压。3.检查控制系统:先摘下高压初级电源031、032。在其两端之间接一灯泡以备观察。(1)观察各控制继电器动作情况:选择器放在“Ⅰ”档,按下手闸 PA,SFJ-5SC 同时动作,此时旋转阳

One fault occurred in the XG-500mA X-ray machine. The result is a normal perspective, and no X-rays occur in the spots or photos. In order to find out the cause of the fault, the filament heating section, the high pressure section and the control system must be checked. The results show: 1. The size of the focus is normal. 2. There is no primary voltage in the high voltage section. 3. Check the control system: First remove the high voltage primary power supply 031, 032. Connect a light bulb between its ends for observation. (1) Observe the action of each control relay: The selector is placed in the “I” file, press the hand brake PA, and the SFJ-5SC simultaneously moves. At this time, the rotation is positive.
