Selection and Study of Pump Type for Caohai ∼ Dianchi Connection Pump Station Project

The Caohai-Dianchi Connection Pump Station Project is part of the Dianchi water quality improvement and stability plan. As a connected pump station connecting Caohai and Dianchi, it plays a role in replacing and cleaning Caohai water. In this paper, based on the construction purpose, layout conditions and parameters of connection pump station, the advantages and disadvantages of centrifugal pumps and mixed flow pumps are given after analysis and comparison from the pump selection principles, stable operation, and economic factor, and the final pump type is determined through comprehensive comparison, which can provide reference value for the design of similar pump stations.
