Closed impeller with self-recirculation casing treatment
Abstract
A closed impeller includes: a housing provided with an opening; an insert inserted into one side of the opening; and an impeller body inserted into the other side of the opening, and including a plurality of blades and a shroud covering the plurality of blades, wherein the insert is provided with an inflow channel guiding a fluid into an inlet of the impeller body, and wherein a clearance between an outer surface of the insert and an inner surface of the housing forms a circulation flow channel connecting the other end of the inflow channel with a portion where one end of the inflow channel meets the inlet of the impeller body.
