| Abstract: | By analysing the main effective factors of vortex in intakes of pumps, the re-lationship of vortex types changed with Fr number is studied, the mechanical criterionneeded in the model test on critical Submergence is determined and the new characteristicparameters were provided. At the same time, the equation of critical Submergence is con-cluded. |
