Theoretical Analysis on Revolution Rate Regulating of Centrifugal Pump vs Energy Saving

Combined with the operating conditions of centrifugal pump, the mathematical analysis on the revolution rate regulating of centrifugal pump vs energy saving has been carried out based on the theoretical study. The horsepower relational expression between the before and after regulating have been derived. The economic analysis on the effectiveness of regulating has been made. The availability on revolution rate regulating of centrifugal pump vs energy saving is described with a case in the paper.
