Oxygen Ground Equipment
Oxygen ground equipment is a test equipment used to check the performance of oxygen supply systems and components of military or civil aircraft. It is suitable for aviation products such as oxygen ground equipment.
Technical Parameters :
Test products: Oxygen gaskets and other aviation products:
Use medium: mixed gas, oxygen:
Can output DA signal 2 channels: 0-10V, 100Hz
Oxygen supply outlet pressure test range: -30-30k P a, load-resistant outlet pressure test
range: 0-200kPa;
Provides a simulated altitude environment of up to 30km;
Oxygen concentration measurement range: 0~100%, indication error: ±3%FS;
Oxygen pressure difference sensor characteristic indicators: repeatability 0.1%, accuracy
0.5%;
The number of data collection channels is no less than 32, the sampling rate is no less than
100K, and the collection accuracy is 1%FS;
Support common communication interfaces such as 232/422/485;
Provide the product with a power supply of 28V 2A or more;
Connected to the product electrical interface through the I0 interface, send instructions to the
product, collect product data, the I0 interface is controlled by a PC, not less than 40
It can automatically and continuously collect and save test curves;
Through the 422 interface, product control instructions can be freely set and product control
programs can be modified to facilitate scientific research debugging;
Modular design of gas circuit allows free combination of gas circuits to meet the testing
requirements of different products;
The low-pressure cabin is mainly used to place test samples and can establish a maximum
altitude environment of 30km. The cabin volume should be no less than
200L:
The convection module can provide a maximum of 18 km, a maximum pressure difference of
34.5 kPa , and a decompression time of 0.3s~0.5s;
Negative pressure chamber volume: 12m3
Features:
Control the simulation altitude environment simulation degree (12km~18km) to increase or
decrease;
Test the anti-g output pressure of the regulator under static conditions; (Connect the anti-g
output port of the regulator, and test the anti-g outlet pressure difference sensor to adjust
The anti-load output pressure of the device under static conditions, directly read the anti-load
output pressure.
Test the regulator's anti-g positive pressure breathing pressurization value under static
conditions; (through the regulator's anti-g input port, apply the required acceleration to the
regulator
The outlet oxygen pressure differential sensor tests the positive pressure breathing pressure
value of the regulator under static conditions, and directly reads the oxygen output
The pressure out.)
Test the opening pressure of each safety valve of the regulator; (When installing components:
gradually increase the input air pressure of the pressure regulating valve and test the opening
pressure of each safety valve of the regulator.
The input flow of the door, the product: input a certain pressure, adjust the output pressure
through the regulator software control, measure the oxygen outlet and anti-load
The pressure at the outlet is the opening pressure of the valve. )
Check the air tightness of the regulator: (Input the required air pressure to the regulator and
test the air tightness of the regulator by measuring the inlet flow rate. Only test the air tightness
of the regulator Oxygen air tightness. )
Connected to the product's electrical interface, sends instructions to the regulator and collects
regulator data;
Can automatically and continuously collect and save test curves;
The regulator control instructions can be freely set and the regulator's control program can be
modified to facilitate scientific research and debugging;
The regulator can be tested with one click according to a fixed process to facilitate production
testing;
It can perform air tightness inspection of the pressure reducer and related performance tests.
(First inflate the pressure reducer, then go to the test bench to test the air tightness.
The oxygen inlet flow meter and pressure differential sensor are used to measure the outlet
flow (200L/min) and outlet pressure (0.4mPa -0.9mPa Measure).
