5、3页XGT-A型车钩尾框磁粉探伤机使用说明书一、概述XGT-A型车钩尾框磁粉探伤机进行多次改进升级，使该机磁化效果更好适应能力更强。该机采用了旋转磁场技术，针对异形件的探伤需要而设计。该探伤机采用被探伤工件垂直吊挂，非接触探伤，结构简单，操作维护方便，使用成本低。磁粉探伤的原理是铁磁性材料被磁化后，在零件表面和近表面有缺陷的地方磁力线发生变形，溢出工件表面形成漏磁场。此时，在工件表面施加磁粉或磁悬液，磁粉就会吸附在缺陷处，显示出缺陷的位置、形状和大小。当磁场方向与缺陷垂直时，漏磁场最强，缺陷检出的灵敏度最高；而磁场方向与缺陷平

6、行或夹角很小（小于20°）时，缺陷不能阻碍磁力线的通过，无漏磁场产生，缺陷不可能被检测出来。因此，采用磁粉探伤要根据零件受力情况分析产生缺陷的可能趋向来选择磁场的方向，这样才能较有把握地检查出零件上的缺陷，不致漏检。XGT-A型车钩尾框磁粉探伤机采用三组相互交叉的磁化线圈，分别接入相位不同的交流电，产生方向随时间不断改变的周期性旋转磁场，对被检测工件进行非接触式磁化，保证工件探伤部位任何方向上的缺陷都能获得较高的探伤灵敏度。该机采用PLC程序控制器实现探伤过程中喷淋与磁化时机的最佳结合，以方便探伤操作，提高探伤可靠性。二、结构

7、及特点XGT-A型车钩尾框磁粉探伤机主要由旋转磁场磁化装置，磁化变压器，可控硅调流控制系统，PLC程序控制及显示系统，磁悬液喷淋、回收系统等组成。2.1采用旋转磁场满足形状复杂异形工件的探伤的要求XGT-A型车钩尾框磁粉探伤机采用了旋转磁场对异形件进行磁化，可联系人：古素华手机：13032960852邮箱：13032960852@136.com第2页共13页XGT-A型车钩尾框磁粉探伤机使用说明书使形状复杂工件探伤部位外表面上任一方向上的缺陷，都有磁场与之垂直，从而获得较高的探伤可靠性。为保证磁场强度，选用了“连续旋转磁场”的

8、磁化方式，磁化电流由调压模块控制，磁化电流大小可根据工件要求随时调整；整个探伤过程由PLC可编程控制器控制，实现了喷液、磁化、间歇的自动循环。2.2工件垂直吊挂，不须摘钩即可探伤，操作简便效率高本探伤机探伤时被探工件垂直吊挂，可在工件转运或上检修作业线的过程中完成探伤，检测效
