Research of Influence of the Inlet Elements Design on a Hydraulic Efficiency of an Intermediate Stage in the BB3-Type Multi-Stage Centrifugal Pumps

Abstract

This article presents the results of computational studies for different options of inlet design in an intermediate stage of a BB3 type multi-stage pump intended for transportation of crude oil and other similar liquids. Hydraulic losses in the flow part elements are compared for three different options of the inlet blades in the return channels of an intermediate stage.
