Technical field：
The present invention relates to a kind of Compressor test platforms, and in particular to a kind of using helium as the closed cycle Compressor test of working medium
Platform.
Background technology：
With the development of society, demand of the human society to the energy is stepped up, nuclear energy has more advantage relative to traditional energy,
And one of scheme of development potentiality of following nuclear power is exactly the high temperature gas cooled reactor of helium turbine, it is safer and more economical for nuclear power
Development provide new thinking.In the component structural of helium turbine, especially using helium compressor as the difficult point of design, helium
At home with all rarely having experience in the world, helium is more difficult to compress than working medium such as air, therefore is calming the anger for the development of compressor
It in machine design process, needs by a large amount of test data, to correct pneumatic design, improves and optimize the pneumatic design of compressor.
Invention content：
The purpose of the present invention is to solve the problems, such as performance test of the domestic compressor using helium as working medium, it has adjustable compressor
The pressure of import helium working medium, compressor inlet helium working medium constant temperature, the interior formation closed cycle of pipeline are more expensive for price
Helium can recycle.It is reasonable in design, it is energy saving, it is easy to promotion and application on a large scale
The technical solution adopted by the present invention is：It is a kind of using helium as the closed cycle Compressor test platform of working medium, including electricity it is mechanical, electrical
Machine chassis, diaphragm coupling, gear-box, torductor, experiment compressor, bellows expansion joint, steady flow segment, current stabilization case, in
Between section, heat exchanger, exhaust section, move back asthma pipeline, move back asthma valve, helium air accumulator, diaphragm type compressor, vacuum pump, lubricating oil station and valve
Door；The motor is installed on motor chassis, and motor is coupled by diaphragm coupling with the input shaft of gear-box, gear-box it is defeated
Shaft couples with torductor, and torductor couples with experiment compressor；Test compressor, bellows expansion joint, current stabilization
Section, current stabilization case, interlude, heat exchanger and exhaust section are sequentially connected；The asthma pipeline that moves back is connect with interlude and exhaust section, moves back asthma
It is equipped on pipeline and moves back asthma valve；Valve is installed on the interlude；The gear-box is connect with profit petrol station, by moistening petrol station
Fuel feeding；The current stabilization case is connect respectively with diaphragm type compressor and vacuum pump；The helium air accumulator respectively with diaphragm type compressor and
Interlude connects.
Further, the exhaust section is connect by bellows expansion joint with experiment compressor.
Further, the Capability of Compressor carried out using helium as working medium is tested, and can also change enclosed according to the actual needs
Working medium in pipeline；
Further, bellows expansion joint is installed respectively in main line compressor inlet and outlet side, to absorb due to Temperature of Working liter
Pipeline thermal expansion caused by height；
Further, heat exchanger can be when will be because of compressor compressed helium working medium, and the helium of the power air inlet heating of consumption carries out
Cooling, achievees the purpose that meet compressor air inlet machine temperature condition；
Further, the switch degree of valve can effectively adjust the back pressure of blower outlet, change the work item of compressor
Part, when carrying out compressor using helium as working medium, the admission of compressor characteristic curves；
Further, helium carries out compressor characteristic curves admission for working medium, can be by moving back asthma valve when compressor will enter surge
The moment of door quickly opens, and will move back asthma pipeline and is connected with main line, meets the purpose that compressor moves back asthma；
Further, current stabilization case can improve the gas incoming uniformity that working medium is helium, meet the inlet air conditions of compressor；
Further, pipeline can be vacuumized by vacuum pump before Compressor test, and is imported by air accumulator with a level pressure
The helium of power meets the admission pressure condition of compressor；
Further, after Compressor test, helium working medium can be compressed in air accumulator by diaphragm type compressor, rare gas can
Recycling；
Further, by adjusting the height of motor chassis, testing stand is applicable to be tested with various sizes of compressor.
Beneficial effects of the present invention：Solve the problems, such as performance test of the domestic compressor using helium as working medium, it has can
The pressure of compressor inlet helium working medium is adjusted, compressor inlet helium working medium constant temperature, pipeline is interior to form closed cycle, for price
More expensive helium can recycle.It is reasonable in design, it is energy saving, it is easy to promotion and application on a large scale.Mainly
Advantage is as follows：
（1）, to provide performance test environment in helium compressor development process；
（2）, helium can be compressed in air accumulator after experiment, can be recycled, to reduce the loss brought by the leakage of helium；
（3）, experiment pipeline be closed cycle, can will be minimized by the pollutions such as environment, noise caused by testing；
（4）, helium compressor design at home beyond example, also rarely have experience in the world.Helium compressor experiment can accumulate
Tired helium compressor design and experiment experience, the reliability of inspection technology design verify helium compressor performance；
（5）, carry out the full Reynolds number of helium compressor Stage testing machine, pair of helium working medium and air working medium in the full range of speeds
Than experiment, helium working medium and the otherness of air working medium are studied, verifies the accuracy of approximate Similar rule.
Description of the drawings：
Fig. 1 is the structure diagram of the present invention.
Specific embodiment：
With reference to Fig. 1, vacuum pump 17 can be used before experiment to be vacuumized in pipeline, by the pressure gauge observable pipeline of testing stand
Vacuum condition, after loine pressure reaches requirement, open the valve of helium air accumulator 15, to filling helium in pipeline, observe again
Pressure gauge in pipeline after reaching required helium pressure, closes the valve of helium air accumulator 15, passes through the motor 1 of testing stand
It is exported as power source, gear-box 4 is driven to accelerate, reach the rotating speed requirement for meeting experiment compressor 6, experiment compressor 6 compresses
The helium working medium flowed into from steady flow segment 8, and by it is compressed with high temperature, high pressure helium working medium along radial line stream
Enter exhaust section 12, heat exchanger 11 cools down the helium working medium of higher temperature, to helium compressor condition for import is met, passes through interlude
10 change helium working medium airflow direction, helium working medium flow through current stabilization case 9 can become flowing it is so more uniform that enter steady flow segment 8
In, it again flows into compressor and forms closed cycle.During the admission of helium working medium Capability of Compressor, move back asthma valve 14 and close completely
It closes, moves back asthma pipeline and be in closed state, by gradually adjusting the aperture of valve 19, improve the back pressure that experiment compressor 6 exports, record
Characteristic line of the experiment compressor 6 using helium as working medium is taken, after valve 19 is adjusted to certain switch degree, tests compressor 6
Edge in surge, for experiment compressor 6 once into surging condition, moment, which opens, moves back asthma valve 14, makes to move back asthma pipeline and is in
Completely open state achievees the purpose that testing compressor 6 moves back asthma, will be in main line using diaphragm type compressor 16 after experiment
Helium working medium be compressed in helium air accumulator 15.It can be applied to helium（Air）Compressor test field for working medium.
