新型KSB叶轮集可靠性和效率于一身

KSB工程师在设计叶片时的另一个重点是在轮毂区域制造漩涡的能力。这种旋转效应使纤维远离叶轮轮毂，并将它们输送到外部。基于数十年的自由流动叶轮设计经验，泵制造商的水力专家采用CFD方法(计算流体动力学)，通过计算机辅助模拟获得泵内部复杂流动过程的详细知识。这导致了F-max叶轮的设计，它能够达到以前只有单通道叶轮才能达到的效率。后续平衡不再需要新的叶轮类型。由于新型叶轮产生的径向力和振动通常低于单通道叶轮，因此提高了轴密封和滚动轴承的使用寿命。因此，F-max叶轮泵只需要极少的维护。更换叶轮本身也很简单。当它们旋转时，自由流动的叶轮产生强烈的漩涡，使泵壳内的固体保持悬浮状态，并与倾斜的吸入区域结合，产生额外的冲洗作用。这大大降低了由长纤维(尤其是湿抹布)引起的叶轮中心堵塞的风险。 These have become a major problem in waste water transport as their use has markedly increased in the last few years. As a result of the trend towards conserving drinking water and separating stormwater and waste water, the waste water to be handled has become “thicker”. This is why operators now demand non-clogging impellers which offer reliable operation without sacrificing high efficiencies, even for small waste water pumps. For transporting acid waste water, too, KSB also supplies impellers made from stainless and acid-resistant duplex steel. It provides protection against pitting and stress corrosion. Stainless steel waste water pumps are primarily used in industrial waste water treatment. White cast iron variants for particularly abrasive media are also available.
