Abstract

Eksenterskruepumpe tilpasset pumping av kompressible fluider, omfattende en indre rotor (1) med et antall gjengestarter (Z) sammen med en tilpasset stator eller ytre rotor (2) som er forsynt med én gjengestart mer (Z+l), og hvor det er tildannet et antall prinsipielt lukkede pumpehulrom (6) som under fluidtransport forskyves fra pumpens innløpsside (A) og til pumpens utløpsside (B) der de blir til åpne utløpshulrom (6c) eksponert for fluidtrykket i en nedstrøms rørledning, og hvor det mellom utløpssiden (B) og det i forhold til utløpssiden (B) nærmest avgrensede prinsipielt lukkede pumpehulrom (6b) er anordnet minst én passasje for tilsiktet tilbakestrømning av fluid fra utløpssiden (B) i et avmålt og tilnærmet konstant omfang slik at trykket under antatte driftsbetingelser tilnærmet utlignes mellom utløpssiden og nevnte pumpehulrom innen pumpehulrommet helt åpnes mot utløpssiden (B).
