Problems solved by technology

[0003] According to different experiment types, the compressor experiment system can be divided into two types: open type and closed type, but the traditional compressor experiment system is only for single-stage or inter-stage air extraction compressor units, which cannot meet the needs of compressed air energy storage systems. The experimental requirements of cold compressors, especially the research requirements of flow-heat transfer coupling mechanism of cold compressors with high inlet and exhaust pressures

Embodiment 1

[0054] figure 2 The situation is shown when the first compressor under test 9 is in experimental test mode. Such as figure 2 As shown, when the experimental system carries out the experimental test of the first compressor under test 9, the first compressor under test 9 is started, the second compressor under test 23 is closed, and the intake pipeline of the second compressor under test 23 needs to be closed. And the shut-off valve on the exhaust pipeline and the shut-off valves 18, 25, 28 and 29 on each linkage communication pipeline, open the shut-off valves 14, 26 on the first tested compressor 9 intake pipeline and the exhaust pipeline. The gas passes through the flow meter 11, flows into the first compressor 9 to be tested for pressurization, then passes through the heat exchanger 33 to lower the temperature, then flows into the surge tank 15 to reduce the air flow pulsation, and finally passes through the main pressure regulator valve 12 and auxiliary pressure regulato...

[0058] Figure 4 It shows the situation during the linkage experiment test of the tested compressor 9-23. see Figure 4 , when the experimental system carries out the linkage experimental test of the tested compressors 9-23, it is necessary to close the shut-off valves 18, 26 and 29, and open the shut-off valves 14, 25 and 28. The gas passes through the flowmeter 11, flows into the first compressor 9 to be tested for pressurization, then passes through the heat exchanger 33 to lower the temperature, then flows into the second compressor 23 under test for further pressure increase, and passes through the heat exchanger 27 to reduce the temperature , and finally reduce the air flow pulsation in the surge tank 15, and then re-enter the first compressor under test 9 after reducing the pressure through the main pressure regulator valve 12 and the auxiliary pressure regulator valve 13 to complete the closed cycle. During the experiment, by adjusting the opening of the main pressur...

Abstract

The invention discloses a double-closed intercooling compressor experiment system, which comprises two compressors to be tested, a rectification and voltage stabilization unit, an air charging and deflation unit, a surge experiment unit and the like. The experimental system is capable of testing single-stage compressors or double-stage intercooled compressors, and is suitable for performance experiments on compressors with stable media such as air, carbon dioxide, and nitrogen, effectively expanding the test range of the test bench; The requirements of the air inlet parameters of the cold compressor, especially the demand for high inlet pressure, so as to truly simulate the flow state of the intercooler compressor and reveal its internal flow-heat transfer coupling mechanism; the experimental system has the ability to perform surge experiments and can carry out compression Research on the mechanism of engine stall and surge, with the ability to test from normal pressure to high pressure.

Description

technical field [0001] The invention belongs to the technical field related to compressor testing, and relates to a compressor experiment system, in particular to a double-closed intercooler compressor experiment system. Background technique [0002] At present, compressed air energy storage has the advantages of not being restricted by geographical conditions, high energy storage efficiency, environmental friendliness, and recyclable waste heat and waste heat. It is considered to be the most potential large-scale physical energy storage technology and has broad market prospects. Combined with the characteristics of the compressed air energy storage system, the air compressor used is usually centrifugal or axial flow. It is necessary to carry out experiments and tests on the aerodynamic and mechanical performance of the compressor to understand the coupling law of its internal flow and heat transfer, so as to meet the requirements of the compressed air storage system. To mee...
