两种设备都可以和氦气回收系统结合使用 <br /> <br /> 集成检漏(背压法)<br /> <br /> 在总体集成漏率检测设备中, 被检对像放在充满一定压强氦气测试容器内, 被检测的示踪气氦气通过漏点泄漏, 可检漏率达10E-10亳巴升/秒, 泄漏的被检件马上就被标记分类. 这种方法有以下特征:<br /> <br /> 测量被检件的总体集成漏率 <br /> 测量精度高, 测量准确性高 <br /> 时间短 <br /> 明确结果判断, 好与坏 <br /> 自动化检测,可同生产线集成一体 <br /> 干法检测 <br /> 客观检测 <br /> <br /> 吸枪检漏(过压法)<br /> <br /> 这种设备采用吸枪,可对漏点进行定位. 被检件抽真空后充入过压氦气, 氦气通过漏点泄出, 被吸枪吸入, 由此确定漏黠的位置及大小. 检测后被检件内的氦气降到大气压力, 然后被真空泵抽空. 其可检漏率可达10E-7毫巴升/秒. 吸枪法方法有下列特点:<br /> <br /> 漏点准确定位 <br /> 漏点的漏率准确检出 <br /> 高的测量准确性 <br /> 重复性的生产错误易于发现 <br /> 无需另外的总体检测, 可用装配后的焊点联接处检漏. <br /> 干法检测 <br /> <br /> <br /> <br /> <br /> <br />
