Abstract

Φυσητήρας τύπου Roots περιλαμβάνει περίβλημα που ορίζει ένα θάλαμο ροτόρων και είσοδο και έξοδο στο θάλαμο ροτόρων. Ένας πρώτος και δεύτερος ρότορας είναι εγκατεστημένοι στον θάλαμο ροτόρων, όπου κάθε ρότορας ορίζει έναν αριθμό λοβών, με τους προσκείμενους λοβούς και το περίβλημα να συνεργάζονται ορίζοντας θαλάμους μεταφοράς αερίου. Ο φυσητήρας είναι διαμορφωμένος έτσι ώστε μια καθαρή παροχή αερίου σε ένα θάλαμο μεταφοράς αερίου να είναι εν γένει ή κατά προσέγγιση σταθερή, οπότε η όποια μεταβολή στην πίεση του αερίου στον θάλαμο μεταφοράς αερίου είναι εν γένει ή κατά προσέγγιση γραμμική, καθώς ο θάλαμος μεταφοράς αερίου πλησιάζει την έξοδο. Σε ένα υπόδειγμα, αυτό επιτυγχάνεται προβλέποντας κανάλια ροής εκτεινόμενα από την έξοδο προς την είσοδο, και από την είσοδο προς την έξοδο, που αντιστοιχούν σε κάθε ρότορα. Τα κανάλια ροής επιτρέπουν στο αέριο να ρέει από την έξοδο υψηλής πιέσεως σε ένα θάλαμο μεταφοράς αερίου και από τον θάλαμο μεταφοράς αερίου στην είσοδο χαμηλής πιέσεως. Η προκύπτουσα βελτίωση στις εξάρσεις πιέσεως που συνδέονται με την αντίστροφη ροή μειώνει ουσιωδώς τα επίπεδα λειτουργικού θορύβου του φυσητήρα.
