Turbo compressor

摘要

The turbocompressor has an electric motor (2) and a multi-stage radial turbocompressor (3), mounted on a common shaft (13) within a gas-tight housing (6). The shaft is supported by spaced electromagnetic radial bearings (5), with a gas seal (19) enclosing the shaft between the electric motor and the radial turbocompressor, the electric motor having an internal space (9a) coupled to an exit opening (6h) passing through the housing. An Independent claim for an installation incorporating a turbocompressor is also included.
