Abstract：The parallel-connection operation characters of the centrifugal pump groups with the same type and pipeline layout are discussed.By simplifying the restrictions of pipeline the variable-speed operation characters of the parallel-connection centrifugal pump groups are analyzed based on the centrifugal pump performance and the similarity principle.The variable-speed mathematical model under the restrained condition of system flow fate is established,based on which the variable-speed operation characteristics are discussed and the relevant calculation methods are given.centrifugal pump group;parallel-connection;variable-speed;operation characters;pump station
