[0049] In this embodiment, the basic structure of the air supply reel and the inflation reel is the same, both consisting of a reel body and a hose wound around the reel body. The main difference is the structure of the inflation / air supply interface set at the end of the hose.

[0050] In this embodiment, it should be noted that the first air supply branch and the second air supply branch supply air for starting the aircraft's engine, and the third air supply branch supplies air for cooling the aircraft's main wheel brake discs, calipers and tires; the air supply pressure of the first air supply branch is 0.147-0.49MPa, and the air supply flow rate is 0.5kg / s, the air supply pressure of the second air supply branch is 1-2MPa, and the air supply flow rate is 0.3kg / s, and the air supply pressure of the third air supply branch is 0.5-0.8MPa.

Furthermore, the third inflation branch is mainly used to inflate the cold air cylinders at the station, and the inflation pressure is 0-35MPa.

[0052] In this embodiment, it is necessary to further explain that the first air supply branch first-stage pressure reducer 101, the first air supply branch second-stage pressure reducer 102 and the second air supply branch pressure reducer 111 are all pilot-operated pressure reducing valves; wherein, the first air supply branch first-stage pressure reducer 101 includes a pilot valve JY5 and a main valve JY7, the first air supply branch second-stage pressure reducer 102 includes a pilot valve JY2 and a main valve JY8, and the second air supply branch pressure reducer 111 includes a pilot valve JY4 and a main valve JY6.

In this embodiment, air supply to the aircraft engine can be controlled not only manually via the air supply valve K14 or the air supply valve K5, but also automatically via the air supply solenoid valve DCF2 or the air supply solenoid valve DCF2, ensuring accurate and flexible air supply.

[0054] Furthermore, as a more preferred embodiment, a pressure sensor SP4 and a one-way valve DX8 are sequentially arranged between the air supply valve K14 and the air supply reel J1, and the air outlet of the one-way valve DX8 is connected to the exhaust pipeline; a pressure sensor SP3 and a one-way valve DX7 are sequentially arranged between the air supply valve K5 and the air supply reel J2, and the air outlet of the one-way valve DX7 is connected to the exhaust pipeline; a pressure sensor SP5 and a one-way valve DX4 are sequentially arranged between the air supply valve K8 and the air supply reel J5, and the air outlet of the one-way valve DX4 is connected to the exhaust pipeline; a pressure sensor SP2 and a one-way valve DX6 are also arranged between the inflation valve K4 and the inflation reel J3, and the air outlet of the one-way valve DX6 is connected to the exhaust pipeline; a one-way valve DX3 is also arranged between the inflation valve K9 and the inflation interface J6, and the air outlet of the one-way valve DX3 is connected to the exhaust pipeline.

If it does not meet the standard, it will not be output to the outside and will be directly emptied to ensure the quality of the gas.

[0056] Furthermore, as a more preferred embodiment, a nitrogen cylinder is also provided in the cabin, and the nitrogen cylinder is connected to the nitrogen cylinder valve QF10.

[0057] In this embodiment, the specifications of the nitrogen cylinder and the cold air cylinder are both 35 MPa and 60 L, and the above cylinders are set in the cabin 2 through the cylinder rack 19.

[0058] In this embodiment, the high-pressure gas source vehicle of the present application can not only realize the supply of cold air, but also provide the supply of nitrogen.

[0059] Furthermore, as a more preferred embodiment, the shelter includes a cabin body and a roof, the cabin body and the roof being detachably connected by connecting bolts, and doors are provided on the left, right, and rear sides of the cabin body. During operation, the high-pressure air source vehicle of the present application can open the doors on both sides of the shelter to ensure the fluidity of airflow inside and outside the shelter. Even in high-temperature environments, heat can be dissipated from the air compressor unit inside the shelter, ensuring the normal operation of the air compressor unit.

[0060] In this embodiment, the working principle of the air compressor is as follows:

[0061] The air compressor consists of a cylinder, piston, suction valve, and exhaust valve to complete the working cycle of suction-compression-exhaust-expansion.

[0062] Under normal operation, gas enters the first-stage cylinder through the air muffler for compression. The gas discharged from the first stage is cooled by the first-stage cooler before entering the second-stage cylinder for compression. The gas discharged from the second stage passes through the second-stage liquid-gas separator after the second-stage cooler to remove the condensed water before entering the third-stage cylinder for compression. The gas discharged from the third stage passes through the third-stage liquid-gas separator after the third-stage cooler to remove the condensed water before entering the fourth-stage cylinder for compression. The gas discharged from the fourth stage passes through the fourth-stage cooler and is discharged through the exhaust pipe to be used.

[0063] In this embodiment, the gas output from the air compressor passes through a two-stage pre-oil removal filter in the drying and purification unit to remove oil contaminants. Molecular sieves in the drying tower absorb moisture from the gas, and then pass through two-stage post-filters to remove impurities. Ultimately, the gas output meets the required high-quality gas specifications. This high-quality gas can be stored in a cold air cylinder or supplied externally via pipelines, shut-off valves, and filters. Pressure is displayed on a display controller and pressure gauge, and the safety of the output gas is ensured by sensors, filters, safety valves, check valves, and vent valves.

[0064] The specific working process and principle of the high-pressure gas source vehicle of this embodiment are as follows:

[0065] (A) Producing and storing cold air

[0066] 1) Connect the power cable of the gas source vehicle to the mains (380V / 50Hz), press the "main power switch" on the control cabinet, and observe that the display should indicate normal operation ("Gas Quality" is red, and the others are green);

[0067] 2) Open the "process gas source output selection valve K1" to the "empty" position, and then open the "gas quality detection valve K7";

[0068] 3) Press the "Air Compressor Start" button to start the air compressor unit, and press the "Start" button of the drying and purification device;

[0069] 4) After the air compressor unit is running, check whether it is running normally and the oil pressure should be within the specified range (0.1~0.7MPa);

[0070] 5) Observe the gas indicators displayed on the display screen of the operation control cabinet. If the gas dew point is lower than -35°C and the number of particles with a particle size greater than or equal to 5μm is 0, it means that the gas quality is qualified;

[0071] 6) After the gas quality is qualified, adjust the "processed gas source output selection valve K1" to the "gas supply" position (at this time, the "inlet valve K2", "inlet valve K3" and "charging valve K9" should be closed) to fill the on-board gas cylinders. The nine cold air cylinders on the gas source vehicle can be filled to 35MPa (Note: Under normal circumstances, the on-board gas cylinder valves should always be open);

[0072] 7) After filling, place the "process gas source output selection valve K1" in the "drain" position and close the "gas quality detection valve K7";

[0073] 8) Press the "Air Compressor Stop" button on the operation panel to stop the air compressor;

[0074] 9) Open the "manual drain valve" on the drying and purification device. After the pressure gauge pointer on the drying and purification device returns to zero, close the "manual drain valve" on the drying and purification device, press the "main power switch", and place the "processed gas source output selection valve K1" in the "off" position to cut off the power.

[0075] (B) Blowing operation

[0076] Before starting the aircraft engine and supplying air to the onboard gas cylinder, a blowpipe operation should be performed. The operation steps are as follows:

[0077] 1) Hold the end of the corresponding branch hose with the air supply port facing outward and remove the dust protection cover or self-sealing joint;

[0078] 2) Open the air inlet valve at the front end of the corresponding branch pressure reducer, and adjust the corresponding branch pressure reducer so that the pressure gauge of the corresponding branch is within the specified range (Note: the air supply valve needs to be opened slowly when starting the aircraft engine), and perform the "blowing" operation for 3 to 5 seconds;

[0079] 3) After the blowpipe operation is completed, close the air inlet valve at the front end of the corresponding branch pressure reducer;

[0080] 4) Open the "drain valve K6" and after the pointer of the "drain pressure gauge B6" returns to zero, close the corresponding branch pressure reducer and the rear-end air supply valve.

[0081] (C) Inflating of onboard low-pressure gas cylinders

[0082] 1) Observe the pressure on "Pressure Gauge B1". It should be higher than the required working pressure. If the pressure is lower than the working pressure, the gas cylinder needs to be refilled (for refilling, follow the "Manufacturing and Storing Cold Air" procedure).
