    • An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.
    • 轴向流动叶轮包括轮毂,至少三个基本叶片和可拆卸地安装到每个基础叶片上的盖板。 当叶轮被施加在具有高密度和粘度的介质环境中时,叶轮将仅通过除去盖板的基础叶片才能满足要求。 当叶轮被施加在具有低密度和粘度的介质环境中时,盖叶片可以安装在基础叶片的前部和/或后部,以便提高叶轮的效率。 在这种情况下,能够在产生等效推进力的同时显着降低电力消耗,有利于节能。 因此,叶轮可以适应不同的介质环境和效率要求,因此具有良好的适应性,投资成本最低,使用方便。
