Abstract (en)

[origin: EP0635643A2] the invention relates to a refrigerant turbo-compressor, preferably of radial design, for the compression of steam under vacuum conditions, possessing a multiplicity of blades. The object is to design the rotor of a radial turbo-compressor in such a way that, at the low density of the conveying medium, preferably steam, the necessarily high volume flows can be conveyed under the pressure conditions required, and in such a way that the strength problems arising from the high circumferential speeds are solved effectively. According to the invention, the rotor consists of blades or blade elements, rotor segments, blade-carrying elements and a hub. These parts consist in their entirety or individually of composite polymeric material, the reinforcing materials of which are preferably carbon fibres. The radially extending elements are connected individually to the hub. The carbon fibres are embedded in the composite material in a manner suitable for undergoing stress.
