EDR—750B型X线机是70年代从原匈牙利进口的X线机,我国仍有不少医院用于常规摄片工作。但是由于使用年代较长,各类故障较多,特别是摄片KV调节系统,该系统发生故障时就会出现“阻塞”报警,导致不能工作。修理该系统,技术上并没有太多的困难,只是需要更换损坏的电路板。如果没有备用同类电路板,修理就非常困难。我院76年购进这台X线机,已经使用了近20年,KV调节系统已修了几十次之多,都没能彻底
The EDR-750B X-ray machine was an X-ray machine imported from Hungary in the 1970s. There are still many hospitals in China that are used for routine photography. However, due to the long service life and various types of failures, especially the photographic KV adjustment system, a “blocking” alarm will occur when the system fails, resulting in an inability to work. Repairing the system is not technically difficult, but it requires replacing the damaged circuit board. If you do not have a spare board of your kind, repairs are very difficult. Our hospital purchased this X-ray machine in 76 years and it has been used for nearly 20 years. The KV adjustment system has been repaired for dozens of times and it has not been able to completely
