Abstract:In the field of mining and metallurgical engineering, centrifugal slurry pumps are widely used as common conveying equipment. When conveying solid-liquid two-phase flow slurry through pipelines requires high conveying pressure, a single slurry pump often fails to meet the requirements. To effectively improve the conveying head, multiple slurry pumps can be combined into a series pump group for conveying. This article introduces the principle and type of centrifugal slurry pump series pump group, deeply analyzes the difficulties of series connection technology, and proposes targeted solutions, simultaneously elaborates on its application in engineering, and explores and proposes future technological development directions. The research results provide reference for the rational application and technological development of centrifugal slurry pump series pump sets, and are expected to further improve the conveying effect and efficiency of solid-liquid two-phase flow slurry in mining and metallurgical engineering.
