Abstract
Насос, содержащий статор, внутри которого установлен расположенный на валу шнек с лопатками и имеющий одну или несколько кольцевых проточек с расположенными в них неподвижными винтовыми статорными лопатками противоположного лопаткам шнека направления, отличающийся тем, что геометрические размеры шнека и кольцевых проточек выбраны из следующих соотношений: ! ! где Dш - наружный диаметр лопаток шнека, ! Dв - внутренний диаметр кольцевых проточек шнека, ! dвт - наружный диаметр втулки шнека.A pump containing a stator, inside which a screw with blades located on the shaft and having one or several annular grooves with fixed screw stator blades opposite the blades of the screw of the direction located in them, characterized in that the geometric dimensions of the screw and ring grooves are selected from the following ratios:! ! where Dш is the outer diameter of the auger blades,! Dв - inner diameter of the annular grooves of the screw,! dwt is the outer diameter of the screw sleeve.
