Portable automatic gas filling equipment

Abstract

The invention discloses portable automatic gas filling equipment which comprises a gas source device and a gas filling control box. The gas source device comprises a high-purity nitrogen storage unit, a common nitrogen storage unit and a compressed air unit. The gas filling control box comprises a high-purity nitrogen output execution module, a common nitrogen output execution module, a compressed air output execution module, a controller and a display control screen, and the high-purity nitrogen output execution module, the common nitrogen output execution module and the compressed air output execution module are connected with the high-purity nitrogen storage unit, the common nitrogen storage unit and the compressed air unit respectively. The portable automatic gas filling equipment adopting the structure is used for conducting gas filling on a buffer strut, an undercarriage, a pressure accumulator, a rotor wing, a tire, an aviation weapon system, a packaging box of ammunition and apparatus and the like of aviation equipment, and has the advantages of complete functions, simple operation, safety, reliability, high integration level, high expansion adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of aviation equipment maintenance and repair, in particular to a portable automatic gas filling device. Background technique [0002] In the prior art, gas with different air pressures and nitrogen contents is required to fill the cushioning struts, landing gear, pressure accumulators, rotors, tires, aviation weapon systems, and ammunition and equipment packing boxes of aviation equipment. The inflatable equipment is complicated to operate and has a single function, which causes inconvenience to the staff. [0003] At the same time, the existing inflatable equipment mainly relies on manual control to adjust the pressure, and the adjustment of the pressure value is not accurate enough, so that the existing equipment cannot meet the inflatable requirements for the charging point with high pressure requirements. It is difficult to control the pressure error range and it is difficult to ensure the gas receiving ...

[0002] In the prior art, gas with different air pressures and nitrogen contents is required for gas filling of cushioning struts, landing gear, pressure accumulators, rotors, tires, aviation weapon systems, ammunition and equipment packing boxes of aviation equipment, and different The inflatable equipment is complicated to operate and has a single function, which causes inconvenience to the staff

[0003] At the same time, the existing inflatable equipment mainly relies on human-controlled pressure regulation, and the adjustment of the pressure value is not accurate enough, so that the existing equipment cannot meet the inflation requirements for the charging point with high pressure requirements. It is difficult to control the pressure error range, and it is difficult to ensure the gas receiving point. safety
