closed impeller type sand pump 闭式叶轮泥浆泵
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.
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。
A smooth power curve, not easy to have a super power, but this type of impeller cavitation performance than ordinary closed impeller, especially suitable for use in the pump pressure on imports.
功率曲线比较平稳，不易产生超功率的问题，但该型叶轮的汽蚀性能不如普通闭式叶轮，尤其适宜用在有压进口的泵上。
