在使用新型的美国 Tif 5650型电子检漏仪修理华中理工大学制冷设备厂生产的 RZS-Ⅲ型日光型植物生长箱(群)过程中,进行不同检测方法对检漏准确性影响的研究.结果表明,即使是技术先进的进口电子检漏仪,检测方法不同对检漏准确性影响较大,若检测方法不当,易误判,造成漏检.正确的检测方法是探头处于检测部位正下方3 mm,探头移动速度<1mm·s~(-1).

 

The influence on detective accuracy of leak detector was tested by using different detective methods during repairing RZS-Ⅲ Plant Growth Chamber produced by Huazhong University of Science and Technology with the newest American Model Tif-5650 Electric Leak Detector.It showed that accuracy varied with different detective method.Misjudgement and other losses would result from unsuitable detective methods.The correct detective method was the probe being 3 mm below from detective position and its removal speed ...

由于氟利昂对大气臭氧层的破坏而严重污染环境,因此,在加强对氟利昂替代物及其技术应用研究与推广的同时,防止或减少现有空调制冷装置泄漏,提高检漏准确性,对减少环境污染有重要意义.蒋能照等(1988)采用了肥皂液和卤素检漏灯的检漏方法,虽然简便易行,但检漏精度低、准确性差
