真空泄漏速率测定

检测项目

静态升压法测定：将被测件抽真空后隔离，监测其内部压力随时间的变化率。通过压力升高值和已知容积计算泄漏速率，适用于总漏率和虚漏的评估。

氦质谱检漏法：使用氦气作为示踪气体，通过质谱仪检测氦气分压的变化。该方法灵敏度极高，能够精确定位和量化微小泄漏。

气泡检漏法：将被测件充入压缩空气并浸入液体中或涂抹发泡液。观察是否有连续气泡产生，用于粗检漏和可见漏点的定位。

压力衰减法：向被测件内充入一定压力的气体，监测在规定时间内压力的下降值。压力损失直接关联于泄漏速率，广泛应用于密封件和容器的测试。

卤素检漏法：利用卤素气体作为示踪剂，通过卤素检漏仪探测其浓度。对特定类型的制冷剂泄漏检测尤为有效。

氢氮混合气检漏法：使用安全比例的氢氮混合气作为示踪气体，配合专用传感器进行检测。该方法安全快速，适用于在线检测场合。

累积检漏法：将泄漏出的示踪气体在密闭收集罩内累积一段时间后再进行测量。此方法可显著提高对小泄漏信号的检测能力。

真空室法检漏：将被测件置于真空室内并充入示踪气体，用连接在真空室上的质谱仪进行检测。适合复杂形状或整体密封性的评估。
