| Abstract: | Based on the operation characteristics of the centrifugal pumps deviated from the design in petrochemical industry,some traditional methods of the retrofit of centrifugal pumps were described,a new design plan of the impellers was proposed of modifying the external diameters of impellers and the wrap angle of the vane,and the primary calculation and simulation methods of determining new external diameters of the impellers were given. |
