| 摘要 |
The invention relates to a compressor system for production of compressed air, consisting of a compressor driven by an internal combustion engine, connected by piping to compressed air discharge points and supplied with precompressed air by an exhaust turbocharger on the drive side connected on the exhaust side of the internal combustion engine. The overall efficiency of such a machine is improved by the positioning in line, on the exhaust gas side, of a first exhaust turbocharger (20), supplying precompressed air to a diesel engine (40), and a second exhaust turbocharger (21), supplying precompressed air to a liquid-injected displacement compressor (50), with the turbine-side wheel geometry, such as the outside wheel diameter, of the exhaust turbocharger (20) being matched to the exhaust backpressure and temperature resulting from the downstream exhaust turbocharger (21) of the displacement compressor (50) and the turbine-side wheel geometry, such as the wheel diameter, of the exhaust turbocharger (21) being matched to the different mass flows on the turbine side and compressor side of the exhaust turbocharger (21).
