Abstract

Et lagersystem i en raffinar for fremstilling av masse, hvor råmaterialet raffineres i en raffineringsspalte mellom minst et par raffineringselementer (22, 24) som dreier i forhold til hverandre, og hvor minst ett av raffinerings- elementene (24) er opplagret på en aksielt bevegelig og drei- bar aksel (26). Lagersystemet omfatter et kombinert hydrosta- tisk/hydrodynamisk aksiallager-arrangement og består av et hus (32) med minst ett dreiestempel (30) som er festet på dreie- akselen (26) for omdreining sammen med denne. En stasjonær holder (29, 33) er anbragt i huset (32) på minst en side av dreiestempelet (30). En ytre og en indre ringsylinder hen- holdsvis (200, 210 og 202, 212) er anordnet aksielt bevegelige i et ytre og et indre kammer henholdsvis (40, 41 og 42, 43) i holderen (29, 33). Ringsylindrene er derved innrettet til å presses mot en endeflate av stempelet (30), slik at det dannes tetningsspalter (211) mellom dem. Mellom ringsylindrene henholdsvis (200, 210 og 202, 212), stempelet (30) og holderen (29, 33) er det avgrenset et hulrom, og en kanal (246, 248) er anordnet for tilførsel av hydraulisk trykkmedium til hulrommet (213, 214) for bestemmelse av stempelets aksielle stilling.
