The optimal hydraulic design can effectively improve the outlet flow pattern of suction box to ensure better flow conditions for pump and raise the efficiency of pumping system substantially.

The experiment shows that by changing the velocity coefficient , the separation of boundary layer on pump vane can be controlled, and the performance of pump is improved and its hydraulic efficiency.

The development application on the hydraulic pump has improved the automation and intelligent level and test efficiency and precision of the experiment course based on virtual instrument.
