Abstract

Flertrinns sentrifugalkompressor som omfatter i det minste ett trinn (10) som omfatter en nedre halve tank (11), en øvre halve tank (12), en rekke nedre halvmembraner (16), en aksel (13) utstyrt med en rekke rotorer (14), en rekke øvre halvmembraner (18), en nedre, halve sugemembran (51), en øvre halve sugemembran (52), idet den nedre halve sugemembranen (51) og den øvre, halve sugemembranen (52) omfatter et parti (71) og et parti (72) egnet til å kobles til de nedre halvmembraner (16) og til de øvre halvmembraner (18), for å danne henholdsvis en første "stabel" (41) av nedre halvmembraner (16) og en andre "stabel" (42) av øvre halvmembraner (18).
