【Abstract】 The method of getting the dynamic model of centrifugal pump is stated in this paper, and the dynamic models based on the external characteristics and interior characteristics are given here. The Hydraulic Transients of a certain centrifugal pump system during starting period is also given in this paper. The results show that both of these methods can get good results. It is valuable to the analysis of the transient characteristics of the feedwater system and the design of the controller.更多还原
