根据子午面流道的静压分布可知，静压提升情况比较理想，但在叶轮进口处存在轻微的静压下降现象，这是由于相对气流角和进口叶片几何角不匹配导致的。在无叶扩压段，工质静压可以进一步增加，说明无叶扩压段设计较为合理。

According to the static pressure distribution of the meridian channel, the static pressure increase is ideal, but there is a slight static pressure drop at the inlet of the impeller, which is caused by the mismatch between the relative flow Angle and the geometrical Angle of the inlet blade. In the section without blade, the static pressure of the working medium can be further increased, indicating that the design of the section without blade is reasonable.
