INTERNAL COMBUSTION ENGINE TURBOCOMPRESSOR TEST BED Russian patent published in 2003 - IPC

FIELD: general and power engineering. SUBSTANCE: proposed test bed is designed for testing machines, particularly, supercharging turbocompressors of internal combustion engines, turbines and compressors. Test bed is furnished with second recuperative heat exchanger, heat exchanger-cooler, adjustable heater and adjustable spoiler. The latter is made in form of housing with central channel to pass gas. Spoiler is furnished with through holes made over housing generatrix. Through holes communicate with atmosphere through controlled valves. Intake main line communicates through inlet with atmosphere being connected with inlet of turbocompressor turbine by means of second circuits of second and first recuperative heat exchangers and adjustable heater. Outlet main line is connected by its outlet with atmosphere. Outlet main line is connected through first circuit of second recuperative heat exchanger and processing compressor with outlet of compressor of turbocompressor. Adjustable spoiler is installed at inlet of compressor of turbocompressor. Outlet of turbine of turbocompressor is connected with first controlled gate. The latter is installed in connecting main line. Outlet of turbine communicates with spoiler by means of first circuit of first recuperative heat exchanger-cooler. Bypass main line is installed in parallel. Second controlled gate is installed in bypass main line. Bushings are installed in through holes of spoiler. Bushings are provided with holes and are installed for turning around axis and axial displacement. Adjustable heater is made in form of electric air heater or steam-gas heat exchanger. The latter is connected through its first circuit with superheated steam source. Second circuit is connected with outlet of second circuit of first recuperative heat exchanger and inlet of turbine of turbocompressor. Invention provides possibility of stimulation and restoration of flow structure at compressor inlet. EFFECT: reduced consumption of energy at testing of turbocompressor. 4 cl, 3 dwg
