| Abstract: | The calculation principle, construction design and the material selection are described for a large-sized cargo oil pump on the basis of model design and model tests. It is stated that the reliability of similarity design can be ensured if the law of similarity is correctly adopted. The influence of the geometric shape of the inlet section of the impeller on the cavitation performance and the efficiency of a centrifugal pump are verified. The domestic material combinations that can be used for marine cargo oil centrifugal pump are also proposed. |
