The liquid nitrogen storage tank is communicated onto the carburetor arranged in the water basin through a valve; the carburetor is communicated with the surge tank; the surge tank is used for supplying gases into the sound generator through the multiple-output transverter. As the adopted technology of the high-capacity liquid nitrogen storage tank and the surge tank for keeping air current pressure stable, the high efficient and high-capacity heat-change technology of the copper tubular product carburetor improves the air supply flow and heat-change efficiency; the volume of the liquid nitrogen storage tank is up to 30m <3>; the volume of the surge tank is up to 30m <3>; the maximal flow of the air supply is up to 400m <3> / min; the maximal pressure is at 1.6 MPa, and the maximal pressure of the outlet is at 1.0 MPa.
Description
Technical field
The utility model relates to the reverberation chamber air supply system, particularly a kind ofly is used for large-scale reverberation chamber, and the reverberation chamber air supply system that can be used as Large Spacecraft and the test of assembly sound thereof.
Background technology
At the used source of the gas of reverberation chamber is with the nitrogen of liquid nitrogen through vaporization.The reverberation chamber air supply system mainly is made up of liquid nitrogen storage tank, buffer tank, carburetor, pipeline, multiple output converter and various valve.But existing reverberation chamber is small-sized reverberation chamber.And large-scale reverberation chamber, it is big to have liquid nitrogen storage tank and a buffer tank volume, and the efficient of carburetor heat interchange requires characteristics such as height.Obviously, for the reverberation chamber that is used for the test of Large Spacecraft and assembly sound thereof, the structure of existing small-sized reverberation chamber air supply system and technical requirement all no longer can be satisfied its technical requirement, thus, be necessary to redesign a kind of large-scale reverberation chamber system, to satisfy the needs of space industry.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that remedies existing small-sized reverberation chamber air supply system technology, keep stream pressure stable by employing high capacity liquid nitrogen storage tank and buffer tank, and adopt copper tubing carburetor to carry out the heat interchange of high-efficiency large capacity.
The utility model provides a kind of large-scale reverberation chamber system, it comprises: liquid nitrogen storage tank, be arranged on carburetor in the pond, keep stable buffer tank, multiple output converter, the acoustic generator of stream pressure, liquid nitrogen storage tank is communicated on the carburetor that is arranged in the pond through valve, carburetor and buffer tank conducting, buffer tank is fed to gas in the acoustic generator via multiple output converter.
In the described system, liquid nitrogen storage tank is provided with the air pressurizing unit that infeeds pressure to liquid nitrogen storage tank.
Further, the quantity of carburetor is 2 covers (using 1 cover, 1 cover backup), and preferred carburetor is the two-way input, two-way output; And carburetor is made up of copper pipe, and copper pipe is soaked in the pond.
Further, the quantity of acoustic generator mostly is 6 most, is divided into low frequency, intermediate frequency and high frequency, can select to use according to testing requirements.
Further, multiple output converter comes pilot-gas pressure and filters the inflow acoustic generator through filter through reduction valve.
Compared with prior art, advantage of the present utility model is: the utility model is owing to adopt the high capacity liquid nitrogen storage tank and buffer tank maintenance stream pressure stabilization technique, the hot swapping of copper tubing carburetor high-efficiency large capacity has improved gas source and flow amount and heat exchanger effectiveness, and liquid nitrogen storage tank volume reaches 30m
3, the buffer tank volume reaches 30m
3, the source of the gas maximum flow reaches 400m
3/ min, maximum pressure are 1.6MPa, and the outlet maximum pressure is 1.0Mpa.
Description of drawings
Fig. 1 is the system schematic of large-scale reverberation chamber of the present utility model.
Wherein, 1, supercharging air valve; 2 liquid nitrogen storage tanks; 3 carburetors; 4 ponds; 5 voltage stabilizers; 6 multiple output converters; 7 valves; 8 acoustic generators.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 has provided the synoptic diagram of large-scale reverberation chamber of the present utility model system.Large-scale reverberation chamber of the present utility model system comprises liquid nitrogen storage tank 2, be arranged on carburetor 3 in the pond 4, keep stable buffer tank 5, multiple output converter 6, the acoustic generator 8 of stream pressure, liquid nitrogen storage tank 2 is communicated on the carburetor 3 that is arranged in the pond 4 through valve 7, carburetor 3 is made up of copper pipe, and copper pipe is soaked in the pond 4.Carburetor 3 is preferably the two-way input, two-way output; Liquid nitrogen storage tank 2 infeeds 3 liang of input ends of carburetor through valve 7,3 liang of output terminals of carburetor and buffer tank 5 conductings, buffer tank 5 is fed to gas in some acoustic generators 8 via multiple output converter 6, acoustic generator 8 has six, be divided into low frequency, intermediate frequency and high frequency, can select to use according to testing requirements.Liquid nitrogen storage tank 2 is provided with the air pressurizing unit 1 that infeeds pressure to liquid nitrogen storage tank 2, so that the liquid nitrogen in the liquid nitrogen storage tank is infeeded in the carburetor 3 in time.Usually, air supply system is vaporizated into nitrogen with the liquid nitrogen in the high capacity liquid nitrogen storage tank 2 through carburetor 3, and air-flow keeps stream pressure stable through buffer tank 5, passes through multiple output converter 6 inflow sound acoustical generators 8 again, and as the air supply source of acoustic generator 8.Wherein, carburetor has adopted the hot swapping of high-efficiency large capacity, and carburetor is a copper equipment, and the gasification total amount of every cover carburetor is 200m
3/ min.
The principle of such scheme is: the pressure of air supply system high capacity liquid nitrogen storage tank in air pressurizing unit increases the liquid nitrogen storage tank, after opening valve, liquid nitrogen is pressed into the carburetor vaporization, 650 times of volumetric expansions become the gas of certain pressure, and air-flow is through the buffer tank voltage stabilizing, arrive multiple output converter through pipeline again, each road output controls to the gas that meets the requirements through reduction valve, filters inflow sound acoustical generator through filter, as the air supply source of acoustic generator.
Above-mentioned embodiment only is used for illustrating the utility model, and it should not be construed is that protection domain of the present utility model is carried out any restriction.And, it will be apparent to those skilled in the art that do not breaking away under the utility model spirit and the principle, to various equivalent variation that the utility model carried out, modification and in the text not the various improvement of description all within the protection domain of this patent.
