| Abstract: | In a condensation and feedwater system, condensate pump outlet pressure fluctuations will appear in some conditions, so related research work is carried out as follows. Through investigating the actual operating parameters of the system, using numerical equation of the characteristic equation of system cavitation margin, the influence of system parameters on boundary condition of condensate pump operation is obtained. And then get the cause of the condensate pump outlet pressure fluctuations, and puts forward the corresponding control measures. |
