| Abstract: | The centrifugal pump is the essential general machinery in the national economy various departments,and the power consumption is high,therefore pump energy conservation significance is very significant. The centrifugal pump without bottom valve movement,then calculates the lose before and after the centrifugal pump cancel the bottom valve,choice absorbing water installs and carries on the design and the efficient analysis. |
