摘要 |
The invention concerns a high-pressure multi-stage centrifugal compressor containing at least two compressor elements (1, 4, 5) which are arranged in series as compressor stages, and at least two electric motors (3, 7) to drive these compressor elements (1, 4, 5), characterised in that, apart from at least one compressor element (1) forming a low-pressure stage and which is driven by an electric motor (3), it contains at least two compressor elements (4, 5) forming high-pressure stages and which are arranged in series and are driven by one and the same second electric motor (7). |
