The important bottleneck problem that restriction air respiratorresuscitator uses, the supply problem of the compressed air gas source breathed for personnel exactly.The inflation method of librarian use in the past, is rely on the air compressor inflation being located at fixed-site, makes pressurized air Filling apparatus to the inflating gas cylinder of resuscitation apparatus.But along with the quantity of onsite application air respiratorresuscitator and frequency constantly increase, in order to ensure carrying out smoothly of overall work, rear security force uses traditional method to the air respiratorresuscitator inflating gas cylinder using up breathing gas, obviously be not suitable with some emergency management and rescue requirements of one's work, limit the use of this personal protective equipment of air respiratorresuscitator.For this reason, some unit, by air compressor, removes and inflates to field.There is the research to all kinds of gas-filled pump outside Present Domestic, have the improvement to natural gas supply system, safe and reliable Journal of Sex Research being devoted to raising system etc.The vehicle-mounted fire-fighting inflation equipment with the large-scale mobile that uses in the fire-fighting and rescue of domestic city, solves on-the-spot air feed problem preferably abroad.The shortcomings such as but it involves great expense, user cost is high, and be not suitable for equipment of small motor rescue and field and execute the task actual demand is inflated to air respiratorresuscitator.
Inventor is realizing finding in process of the present utility model that the defect of prior art is:
When performing emergency management and rescue task, field condition proposes very high requirement to air respiratorresuscitator inflation to charging efficiency, need air respiratorresuscitator each gas cylinder to substitute the bad for the good within a short period of time, multiple gas cylinder can be filled within a period of time and in gas cylinder air quality better.And present case, pressurized air charger is that the inflationtime of every gas cylinder (6.8L) is generally at about 8 minutes.Can heat be produced in gas replenishment process, have impact, and the apparatus overheat that works long hours to inflation gas cylinder, generally take continuous operation orderly closedown cooling 10-20 minute after 1 hour.These have impact on the efficiency of inflation.
For giving air respiratorresuscitator inflating gas cylinder efficiency high in satisfied on-the-spot a period of time in the wild, need solution two subject matters further: one is short as far as possible to each inflating gas cylinder time under guarantee safety and gas cylinder prerequisite in working life.Two is make charger continuous working period extend within a certain period of time, can fill multiple gas cylinder.To consider simultaneously its cost expense and user cost not high, be suitable for equipment of small motor rescue and the feature such as field action.Have no solution preferably at present.

Model utility content
Technology of the present utility model is dealt with problems: overcome the deficiency of existing field inflation to emergent on-the-spot fast aeration, improve charging efficiency, solves air respiratorresuscitator each gas cylinder and to substitute the bad for the good, can fill within a period of time within a short period of time the problem of multiple gas cylinder.Invention one is field quick air-inflating apparatus safely and efficiently.
The technical solution of the utility model:
(1) concrete resolving ideas
For problem one, how solving single air cylinder, to be full of the pressurized gas time short as far as possible.Analyzing current practice is utilize air compressor to inflate, and compresses step by step, make air in air respiratorresuscitator gas cylinder reach 30MPa pressure, and be full of gas cylinder capacity atmospheric air.If the time that its single air cylinder is full of gas is T, compression time atmosphere gas being compressed to 30MPa gas is T1, and the filling time of filling the 30MPa gas of full gas cylinder capacity is T2, i.e. T=T1+T2.Through experimental research, for under giving the short as far as possible constraint conditio of single air cylinder inflationtime, adopt the method for isobaric convection current tonifying Qi, the pressurized air that 30MPa pressure is housed directly is filled to gas cylinder, omit the T1 time, reach single air cylinder to be full of the gas time and only to need the filling time to be T2, accomplish that the time is short as far as possible.Namely high-pressure gas cylinder group capacious is adopted directly to carbon fiber gas cylinder " filling ", inflator work ahead can be equivalent to.
For problem two, how within a period of time, to fill multiple gas cylinder.Because in fast aeration process, pressure change can make gas cylinder produce heat, for ensureing safety and gas cylinder working life, temperature variation when we will control inflating gas cylinder.The current apparatus overheat that works long hours, generally take continuous operation after 1 hour orderly closedown cooling 10-20 minute.Take power generating ratio cool time, extension device operating time, inflate to multiple gas cylinder simultaneously simultaneously, really realize fast aeration.
As known from the above, the gas charging system that charging efficiency is high should be: huge discharge inflator+continual work of jumbo air cylinder group+inflator.
Through carrying out experimental research and numerical simulation to fast aeration process, because the temperature effect in gas replenishment process affects serviceability temperature restriction and the inflation rate of gas cylinder simultaneously during fast aeration, therefore while shortening inflationtime, how control temperature effect just becomes is improved charging efficiency and the key guaranteeing gas cylinder safely.Although experiment shows that improving bleed pressure can increase inflation rate, increases and has added operating cost.Improve inflation rate and increase between source of the gas gas storage volume and have a cost analysis optimum value, this needs to analyze in light of the circumstances.
Use flowing law and the seal container temperature changing regularity of pipeline inner fluid in mass-changed system thermodynamics and gas dynamics theoretical research seal container fast aeration process.If initial time, the gas parameter in container is p1, T1, m1.Open valve, after the inflation t time, gas in container parameter is pt, Tt, mt.After gas charging system itself is determined, before and after inflation, the change of temperature is relevant with pt/p1, has nothing to do with the size of container itself.This is because gas replenishment process can be interpreted as physical essence and carry out adiabatic compression to former gas in a reservoir, and mix the synthesis result of these two processes mutually with insufflation gas.Experiment shows that the temperature notable change in fast aeration process mainly appears at the incipient stage, as long as illustrate that the temperature effect weakening the incipient stage just can control the temperature effect in whole gas replenishment process.
Concrete measure: one is the downward trend controlling inflation actual pressure ratio, even if bleed pressure step variation, effectively can avoid the container temperature rise caused by " pressure waste ", thus vessel temp is comparatively declined to a great extent without in control situation.Two is pass through radiating and cooling.Adopt for this reason and control the method for each device temperature increasing degree, power generating ratio cool time, the extension device operating time, inflate to multiple gas cylinder simultaneously simultaneously, really realize fast aeration.
