故障现象打开主机总电源,在透视管电流和透视时间显示器上出现了F6故障码。踩脚闸透视,监视器上无影像。点片摄影无电流,胶片洗出来为白片,全机处于保护状态。故障分析与检修本机故障显示F6,提示X线管灯丝加热电路异常。X线管灯丝加热电路包括:灯丝电流设定电路、灯丝电流比较
Symptom Open the main power supply of the host, in the perspective of tube current and fluoroscopy time display F6 fault code. Tread foot brake perspective, no image on the monitor. No film current photography, the film was washed out for the white film, the whole state of protection. Fault Analysis and Troubleshooting Local fault display F6, suggesting X-ray tube filament heating circuit is abnormal. X-ray tube filament heating circuit includes: filament current setting circuit, filament current comparison
