20130011285 | THREE-STAGE SCREW COMPRESSOR - A multi-staged screw compressor system includes a gearbox, a drive gear located in the gearbox, and a first, second and third screw compressor that are fastened to the gearbox and coupled to the drive gear such that the first, second, and third screw compressors are all driven in common by the drive gear. During operation the first screw compressor compresses a flow of gaseous fluid from an inlet pressure to a first intermediate pressure, the second screw compressor compresses the flow of fluid from the first intermediate pressure to a second intermediate pressure, and the third screw compressor compresses the flow of fluid from the second intermediate pressure to a final pressure. The final pressure is at least thirty times the inlet pressure. | 01-10-2013 |
