ABSTRACT
The transient behavior of a centrifugal pump is theoretically analyzed for different transient processes. In the process of starting, stopping and frequency control, transient behavior in centrifugal pump must come into being. In the process of regulating flowrate, there is no transient behavior in centrifugal pump with radial straight vanes, while transient behavior in common centrifugal pump with back curved vanes is directly related to regulating rule of flowrate. The results of numerical simulation show that rotor-stator interaction is strongest when relative position between vane and volute tongue is nearest. The process of regulating flowrate is a coupling process brought by rotor-stator interaction and varying flowrate.
