Solution to Air Leakage of Cable Sealing in Low Pressure Test
The aircraft harness is known as the"nervous system"of the aircraft,which is responsible for the power transmission and distribution function and signal transmission function of the whole aircraft.With the development,the cables and connectors become more and more complex and numerous.Each independent system equipment is composed of a complex set of cables and cooling pipes.The cooling part may include cooling ventilation pipes,oil pipes and liquid nitrogen pipes.During the low air pressure test,this kind of cable extends out of the box through the lead hole of the low air pressure test box,and needs to be sealed to make the box meet the required low air pressure environment.This paper analyzes the causes of low air pressure leakage,pretreates different cables and pipes,and adopts different sealing methods and sealing media for sealing,and summarizes them.
