通过对该泵内部流动速度、压力分布与捕捉到的流动冲击、二次流、回流等重要现象的分析，给该泵的性能改善与改进提供可靠的信息。

Useful information for the performance improvement was got from the distribution of inner flow velocity and pressure, flows impact, secondary flow and recirculation in the helix centrifugal pump.

成形压力沿半径方向呈不均匀分布，可用线性或二次函数曲线进行近似表示。

The pressure distributing law is non-uniform along radius direction, which could be expressed approximately as the linear or quadratic function curve.

研究结果表明，法向压力在模型铲刀表面呈二次曲面分布，在模型铲刀的中部取得最大值。

The experimental result shows that the normal pressure distribution on the surface of the model blade is a conicoid, the maximum of the normal pressure is in the middle of the model blade.
