XG-200型X线机诊断床上的电源通路、床面升降、铅门开闭和点片摄影操纵失灵遇到这类故障时,不必先拆机检查线路,可听声音初步判断毛病所在。上述几部分控制的方式都采用带弹性的机械装置间接带动一个微动开关,使执行机构工作。在正常情况下,按下按钮或松开按钮应各听到一个清脆的嘀嗒声(机壳内微动开关跳动时发出)。如图1中所示,机械装置由于种种原因常使微动开关不能复位或没有压下。如按下去有声音而机器仍不得电,可按“断”按钮,发觉听不到嘀嗒声,这是由于微动开关被卡
XG-200 X-ray machine diagnosis of bed power access, bed movements, lead-door opening and closing and point photography failure to operate such problems, you do not have to disassemble to check the line, the audible sound to determine the initial fault lies. The above several parts of the control methods are used with elastic mechanical devices indirectly drive a micro switch, so that the implementing agencies. Under normal conditions, you should hear a crisp ticking sound when the button is pressed or the button is released (emitted when the micro switch in the cabinet beats). As shown in FIG. 1, the mechanical device often makes it impossible for the micro switch to be reset or not pressed down for various reasons. If you press the sound and the machine still can not power, press the “off” button, you can not hear the ticking, which is due to the micro-switch is stuck
