| Abstract: | Directing against the field efficiency test of labyrinth sealed large scale feedwater pump, a calculation method for measuring and calculating the feedwater pump efficiency and its shaft power has been given. Through illustration examples obtained from performance tests of labyrinth sealed feedwater pumps in two power plants, it is believed that the said measuring method and calculation formula have strong feasibility for field performance test of labyrinth sealed largescale feedwater pumps, being simple and convenient, fully satisfying the accuracy of C grade required by standard GB 32 16-89. |
