Embodiment 1

[0045] Such as figure 2 As shown, when the compressor experiment test needs to be carried out, the tested test section 6 is set to a tested compressor, and the compressor and expander comprehensive experiment system of the present invention is switched to the compressor experiment test mode. At this time, the circuit needs to be opened On-off valve 15, the inlet pipeline of the tested compressor 6 is provided with a rectifier 7, a flow meter 8 and a first throttle valve group 9 / 10, and the outlet pipeline is provided with a heat exchanger 22 and a second throttle valve group 20 / twenty one. The gas passes through the flowmeter 8 and the rectifying device 7, flows into the compressor 6 under test for pressurization, then passes through the heat exchanger 22 to reduce the temperature, and then passes through the second throttling valve group 20 / 21 to reduce the pressure and then flows into the gas-filled surge tank 16 And in the degassing pressure-stabilizing tank 11, finally ...

Embodiment 2

[0050] Such as image 3As shown, when the expander experiment test needs to be carried out, the tested test section 6 is set as a tested expander, and the compressor and expander comprehensive experimental system of the present invention is switched to the expander experimental test mode. At this time, the circuit needs to be closed The on-off valve 15, the inlet pipeline of the tested expander 6 is equipped with an inflatable surge tank 16, the second throttle valve group 20 / 21 and a heat exchanger 22, and the outlet pipeline is equipped with a rectification device 7, a flow meter 8, a first Throttle valve group 9 / 10 and bleed surge tank 11. The high-pressure air (from the high-pressure air source or the air compressor 19) passes through the inflatable surge tank 16, flows into the heat exchanger 22 to increase the temperature after the second throttle valve group 20 / 21 reduces the pressure, and then flows into the expander 6 under test Reduce the pressure, then pass through...

Abstract

The invention discloses a compressor and expander comprehensive experiment system, including a power unit, a test section to be tested, an air charging unit, a heat exchange unit, etc.; , carbon dioxide, nitrogen and other stable medium performance experiments, effectively expanding the test range of the test bench; the experimental system has a high-efficiency heat exchange system, which can meet the requirements of compressors or expanders for different intake parameters, so as to truly simulate the flow state. Reveal its internal flow-heat transfer coupling mechanism; the frequency converter used in the experimental system is a four-quadrant frequency converter. During the experiment of the expander, the input current of the frequency converter flows from the frequency converter to the power grid, which has the ability to feed back to the power grid.
