JC-20型晶体分析X光机,原机配有可拆式X-射线管。根据该机使用情况,为获得X-射线管所需的真空度常需数小时,不能满足教学和科研需要。有关可拆式X-射线管和封闭式X-射线管的利弊,在许多专著中已有论述。据此,我们在分析原机结构特点和技术性能的基础上,决定用丹东仪表元件厂生产的JX-50系列结构分析用X-射线管(以下简称JX-50)代替原机的可拆式X-射线管,对该机进行改装。 (一)改装的技术依据原机系半波自整流。整机由油浸高压发生器、控制台和可拆式X-射线管及其真空水冷系统组成。采用
JC-20 crystal analysis X-ray machine, the original machine with a detachable X-ray tube. According to the use of aircraft, in order to obtain the required degree of vacuum X-ray tube often take several hours, can not meet the teaching and research needs. The advantages and disadvantages of detachable X-ray tubes and closed-tube X-ray tubes have been discussed in many monographs. Accordingly, based on the analysis of the structural characteristics and technical performance of the original machine, we decided to replace the original machine with the X-ray tube (hereinafter referred to as JX-50) of JX-50 series structure analysis produced by Dandong Instrument Components Factory X-ray tube, the aircraft modification. (A) modified technology based on the original machine half-wave self-rectification. The whole machine consists of oil pressure generator, console and detachable X-ray tube and its vacuum water cooling system. use
