In order to improve the performance of submersible axial flow pump and master the rule of its inside flow,by means of the standard k-ε turbulence model and SIMPLEC algorithm,a CDF analysis was made of the full flow passage in this type of pump.

However, the efficiency of submersible axial flow pump which made in our country is lower about 5-15% than the foreign ones.

In this paper,concerning the working characteristics of a certain model of diving turbine pump,the problems of original design were analyzed firstly,then the forces thrown on the linking sect were also analyzed,inanly a new conceptual model was built and it was analyzed by FEA,so a new design of the linking sect structure was succsessfully completed,and it shortens the design cycle and saves cost.

The LQS two-phase flow submersible pump system used in the standardization embankment building of the Yellow River composes 3 two-phase flow submersible pumps and 2 sludge pumps forming as a complicated series and parallel connection system.
