Example Embodiment

[0022] Reference figure 1 Before the test, the vacuum pump 17 can be used to vacuum the pipeline. The vacuum condition in the pipeline can be observed through the pressure gauge of the test bench. After the pipeline pressure reaches the required, open the valve of the helium gas storage tank 15 and check the pipeline Fill helium, observe the pressure gauge in the pipeline again, after reaching the required helium pressure, close the valve of the helium gas storage tank 15, and use the motor 1 of the test bench as the power source to output, drive the gearbox 4 to accelerate to To meet the speed requirements of the test compressor 6, the test compressor 6 compresses the helium working medium flowing in from the steady flow section 8, and flows the compressed helium working medium with high temperature and high pressure along the radial pipeline. In the gas section 12, the heat exchanger 11 cools the helium working medium at a higher temperature until it meets the inlet condition...

Abstract

The invention relates to a compressor test bench, in particular to a closed circulating compressor test bench with helium as a working medium. A motor is installed on a base bottom frame, the motor isconnected with an input shaft of a gearbox through a diaphragm coupling, an output shaft of the gearbox is connected with a torque measuring instrument, and the torque measuring instrument is connected with a test compressor. The test compressor, corrugated pipe expansion joints, a flow stabilization section, a flow stabilization box, a middle section, a heat exchanger and an exhaust section areconnected in sequence. An exiting surge pipeline is connected with the middle section and the exhaust section and provided with an exiting surge valve. The middle section is provided with a valve. Thegearbox is connected with a lubricating oil station and supplies oil through the lubricating oil station. The flow stabilization box is connected with a diaphragm compressor and a vacuum pump. A helium storage tank is connected with the diaphragm compressor and the middle section. The performance testing problem of a domestic compressor with helium as a working medium is solved. The structural design is reasonable, energy is saved, and the closed circulating compressor test bench is easily applied and popularized on a large scale.

Description

Technical field: [0001] The invention relates to a compressor test stand, in particular to a closed cycle compressor test stand using helium as a working medium. Background technique: [0002] With the development of society, the demand for energy in human society is gradually increasing, and nuclear energy has more advantages than traditional energy sources. One of the potential solutions for the development of nuclear power in the future is the high-temperature gas-cooled reactor of helium turbine, which is safer for nuclear power. And more economical development provides new ideas. In the structure of parts and components of helium turbines, especially the design of helium compressors is a difficult point. There is little experience in the development of helium compressors at home and abroad. Helium is more difficult to compress than air and other working fluids. In the process of compressor design, a large amount of test data is needed to correct the aerodynamic design,...
