Abstract

Et opplagringssystem for rotorer i turbomaskiner utmerker seg ved at hvert lager- og tetningspunkt for rotoren (16) er i formen av en lager- og tetningskombinasjon (17) som er tilformet av en stator (18) anbrakt inne i et turbomaskinhus, og som omgir rotoren (16). Statoren (18) er tilformet med en boring (19), slik at det dannes en ringformet spalte mellom stator og rotor, og boringen (19) har gradvis økende tverrsnittsareal i retning mot høyere trykk (P2) i turbomaskinen.A storage system for rotors in turbo engines is characterized in that each bearing and sealing point of the rotor (16) is in the form of a bearing and sealing combination (17) formed by a stator (18) disposed inside a turbo engine housing, which surrounds rotors (16). The stator (18) is formed with a bore (19) so that an annular gap is formed between the stator and rotor, and the bore (19) has gradually increasing cross-sectional area in the direction of higher pressure (P2) in the turbo machine.
