Accompanying drawing explanation
Fig. 1 is the structural representation of described sea level elevation simulator.
Embodiment
The atmospheric value that sea level elevation simulator main simulation different altitude height is corresponding, also can altitude simulating height on the impact of temperature and humidity.
Sea level elevation simulator system construction figure is as shown in Figure 1:
Described sea level elevation simulator comprises: airtight sea level elevation simulation chamber 1, vacuum pump 2, vacuum air storage tank 3, throttling valve or pressure maintaining valve 4, vacuum meter or sea level elevation meter 5, thermosistor 6, intake-air throttle valve 7, gas meter 8, air cleaner 9, controller 10, man-machine interface 11, humidistat 12.
Wherein first five items can form the simplest sea level elevation simulator, increase the simulation that thermosistor 6 can realize the impact of temperature relative elevation height change, increase the impact that in intake-air throttle valve 7, gas meter 8, the adjustable supplementary simulation chamber of air cleaner 9, certain gas componant consumes.Increase controller 10, man-machine interface 11 can realize numeral setting height above sea level angle value, and system realizes atmospheric pressure simulation and relative temperature, the humidity change modeling of set height above sea level angle value automatically.Increase the simulation that humidistat 12 can realize the impact of humidity relative elevation height change.
Sea level elevation simulator principle of work is as described below:
According to sea level elevation and atmospheric corresponding relation, vacuum pump 2 and vacuum air storage tank 3 maintain a vacuum source, control sea level elevation simulation chamber 1 by pressure maintaining valve or throttling valve 4 and maintain certain constant low-pressure state, namely simulate certain specific sea level elevation state, show height above sea level angle value (using vacuum meter to do numerical transformation) by sea level elevation meter or vacuum meter 5.
Thermosistor 6 can change the temperature of sea level elevation simulation chamber 1, the impact that analog temperature changes with sea level elevation.
Intake-air throttle valve 7, flowmeter 8, air cleaner 9 can be the chemical depletion of equipment under test to certain gas componant in simulation chamber and supplements, and makes chemical reaction be equivalent to the environment of High aititude open spaces.
