First input end 42 connect, each air compression unit 1 is for extracting air and to extraction from air
Air carry out filtering compression and generate compressed air, buffering constant voltage unit 2 is for delaying compressed air
Rush constant voltage；The input 52 of pressure transducer 5 is connected with the first outfan 31 of heat radiation drying unit 3,
The outfan 51 of pressure transducer 5 is connected with the first input end 62 of control unit 6, control unit 6
The first outfan 61 be connected with the start end 12 of each air compression unit 1；Pressure transducer 5 is used
The force value of air in monitoring enters oxygen absorbing unit 4 processed, and force value is transferred to control unit 6；
Control unit 6 is for sending control letter when force value is less than the first predetermined threshold value to air compression unit 1
Number, to increase the startup quantity of air compression unit 1.
Oxygenerator of the present utility model at least includes two air compression unit, as it is shown in figure 1, this reality
4 air compression unit 1 (1a-1d) are included, these 4 air compression unit 1 with novel oxygenerator
Being in the mode of parallel connection, it all includes that an air entry communicated with air is for extracting the air in the external world also
And be compressed the air extracted subsequently filtering generation compressed air, its first outfan 11 is respectively with slow
The first input end 22 rushing constant voltage unit 2 connects.When air compression unit 1 completes the filtration pressure of air
After contracting processes, the compressed air with certain pressure can be inputted to buffering constant voltage unit 2, buffer constant voltage
The compressed air entered can be played the effect of buffering pressure regulation by unit 2, compressed air is inputted extremely the most again
In heat radiation drying unit 3, compressed air can be condensed into water through the steam therein that dispels the heat, through dissipating
After rotating separation device in heated drying unit 3 processes, moisture can complete to separate with gas, thus is done
Dry compressed air.The compressed air being dried enters oxygen absorbing unit processed after heat radiation drying unit 3 output
4, the molecular sieve in oxygen absorbing unit 4 processed, can be right after touching the compressed air being dried with pressure
The compressed air being dried carries out nitrogen adsorption, and then obtains oxygen.
Owing to the molecular sieve of absorption nitrogen is at various pressures for the absorbability difference of nitrogen, only enter
After entering the requirement that the air pressure of molecular sieve reaches certain, molecular sieve just can complete the absorption to nitrogen.Cause
And under different height above sea levels, in order to meet the demand of oxygen making amount, for entering oxygen absorbing unit 4 processed
Compressed-air actuated air inflow need to be adjusted such that it reaches the absorption demand of molecular sieve.This practicality is new
The oxygenerator of type can be applicable to the highlands of various height above sea level, by the pressure of the nitrogen adsorption of molecular sieve
Power demand limits as to the compressed-air actuated pressure entering oxygen absorbing unit 4 processed, and this pressure is currently
Molecular sieve can complete the optimal compression air inlet amount of nitrogen adsorption, the first the most above-mentioned predetermined threshold value.
General, when any height above sea level that height above sea level is 0-5000m, this first predetermined threshold value is
0.22-0.23MPa, this first predetermined threshold value can be manually set and be stored in control unit 6.
When oxygenerator of the present utility model is after energising starts, and control unit 6 can be first to First air pressure
Contracting unit 1a send control signal start its run, this air compression unit 1a complete air compression,
After buffering constant voltage, drying steps, pressure transducer 5 can will enter output from heat radiation drying unit
The compressed air being dried entered in oxygen absorbing unit 4 processed carries out pressure detecting, and by the tool of this pressure detecting
Body result is transferred to control unit 6, the pressure that now control unit 6 can will receive in the way of the signal of telecommunication
Force value compares with the first predetermined threshold value being stored therein in, when the force value received is pre-less than first
If (entering the dry compressed-air actuated pressure in oxygen absorbing unit 4 processed and be not up to molecular sieve suction during threshold value
The pressure demand of attached nitrogen), control unit 6 can send control signal to air compression unit 1b and start it

Enough meet pressure transducer 5 for from heat radiation drying unit 3 output be dried compressed-air actuated real-time monitoring,
Preferably, threeway can be positioned close to the side of oxygen absorbing unit 4 processed, such as single from oxygen processed absorption
Unit 4 about 20cm, this setting ensure that pressure transducer 5 to monitor the most accurately will enter oxygen processed suction
Dried compressed air pressure in coupon unit 4, it is to avoid owing to heat radiation drying unit 3 and oxygen processed adsorb
Between unit 4, pipeline such as gets rusty at the pressure error being likely to result in.
It is high that of the present utility model and machine constant pressure type height above sea level self adaptation adsorption oxygen-preparation machine is applicable to Different Altitude
The area of degree, enters the air supply in oxygen absorbing unit 4 processed by monitoring and controls air compression unit
Startup quantity thus regulate the rate of air sucked in required of air to external world and rate of air sucked in required can be finely adjusted, meet inhale
Attached molecule sieve is for the optimal adsorption ability of nitrogen, and is finally issued at current altitude high in optimum energy consumption
Oxygen demand processed under Du.
