Abstract

Flertrinnssentrifugalkompressor som har en tank som kan åpnes horisontalt, omfattende en nedre halv tank (11), en øvre halv tank (12), en aksel (13) med en rekke rotorer (14), og en rekke trinn (10) som hvert omfatter en rekke nedre halvmembraner (16) og en rekke øvre halvmembraner (18), en nedre halvring (21) og en øvre halvring (22) som kan kobles til å danne en bærende ring, idet den nedre halvringen (21) er festet innvendig i den nedre halve tanken (11), og den tilsvarende øvre halvringen (22) er festet til den øvre halve tanken (12), i hvert trinn (10) i flertrinnssentrifugalkompressoren, idet de nedre halvmembraner (16) er fastgjort til hverandre av sperremidler, for å danne en første "stabel" (41) av nedre halvmembraner (16), og de tilsvarende øvre halvmembraner (18) er fastgjort til hverandre av sperremidler, for å danne en andre "stabel" (42) av nedre halvmembraner (16), idet den første "stabelen" (41) kan fastgjøres til den nedre halvringen (21) og den andre "stabelen" (42) kan fastgjøres til den øvre halvringen (22).
