X 线机器正常运转,是放射科工作的基本保证。但是在日常工作中机器经常发生故障,若不及时排除势必影响工作。有些进口机器原件损坏无配件更换,往往给修理带来困难。我科所用东德、匈牙利机器,在平时的修理中有两点小经验愿介绍给同道,不妥之处垦请指正。巧换计时器东德 VEM—50MAX 线机系40年代产品,长期使用,机器上的机械计时器因为齿轮磨损,造成接触不良,计时不准,成为影响曝光的因素。大家知道,X 线透视时其输出量小,对 X 线发射时间要求不甚严格,只要在透视高压初级线路中串联一个脚闸,即可控制 X 线发生。但是 The normal operation of the X-ray machine is the basic guarantee for radiological work. However, in the daily work of the machine often fails, if not eliminated in time is bound to affect the work. Some imported machinery damaged parts without replacement, often to repair difficulties. Our department used East Germany, Hungary machines, in the usual repairs have two little experience is willing to introduce to fellow, improper reclamation please correct me. Clever timer East Germany VEM-50MAX line 40 years of products, long-term use, mechanical timer on the machine because of gear wear, resulting in poor contact, timing is not allowed to become a factor affecting the exposure. We all know that X-ray output when its small, less demanding on the X-ray launch time, as long as a series of foot gate in the perspective of high voltage primary circuit, you can control the X-ray. but
