两者结合，可以实现高效、精密、可靠、整体制造三元流闭式叶轮的目标。
To sum up, a 3d-flow closed impeller can be machined efficiently, precisely, reliably and integrally with this method.
从性能上讲，该叶轮效率较低，仅相当于普通闭式叶轮的70%左右，扬程曲线比较平坦。
From the performance perspective, the lower the efficiency of the impeller, the impeller is only equivalent to an ordinary closed around 70%, a relatively flat head curve.
从性能上讲，该型式叶轮效率高和普通闭式叶轮相差不大，但用该型式叶轮泵扬程曲线较为陡降。
From the performance perspective, the type of impeller and the general efficiency closed impeller or less the same, but the type of impeller pump head curve dropped more.
