Background
Leak checking of oxygen systems during aircraft maintenance has been an important item of oxygen system inspection and a common failure. The original inspection method for the soapy water not only can pollute the plane, but also directly influences the inspection effect due to the concentration of the soapy water, and is not easy to master by a novice. Even if the soap water is too diluted or smeared, the soap water can drop into the equipment cabin to pollute other equipment. Under the temperature of zero, soapy water can not be used at all. In order to meet the requirement of an airplane on a high and cold flying task, aiming at the detection of oxygen leakage points in the high and cold area at the present stage, the leakage detection of an oxygen system is carried out under the condition that the traditional soapy water detection method is not applicable under the low-temperature environment (the soapy water is frozen at low temperature).
