Air conditioning helium filling and recovery system
This helium-filled recovery system is used for helium-filled recovery leak detection in air conditioning systems. First, nitrogen with 4.5Mpa pressure was used to test the large leakage tightness of the inspected workpiece, and then the inspected workpiece was filled with 2.0MPa helium and the helium mass spectrometry leakage detection air tightness test was carried out by sniffing method, and then the helium in the inspected workpiece was recovered and recycled. Through this device, the qualified products and unqualified products in the leaked workpiece are judged, as well as the location of the leakage points of the unqualified products.
