    SMTU SMTU 3d
    SMTU 工业用三螺杆泵,适合低中压(1.160 磅/平方英寸)下使用。SMTU 泵是一款可靠的低噪音设备,适用于要求使用寿命长且成本低的应用领域,如符合美国法规的家用电梯和升降机。SMTU 是一款装配于泵体内的灌液泵。泵体内有三个螺杆旋转,螺杆的设计可避免产生任何轴向荷载。功能压力在主螺杆的平衡活塞与周围泵体之间形成容差。这会在螺杆上产生平衡水动力,同时润滑和冷却密封组件。抽出的流体以液压方式传输移动侧面螺杆所需的扭矩。这意味着螺杆旋转过程中不会发生磨损。

    通过采用高质量的螺杆制造工艺,确保其噪音和脉动极小。

    按照几何设计,三个螺杆间形成了密封腔。在螺杆旋转过程中,主螺杆形成某种类型的空腔,它容纳水流并将水流按轴向从入口排出至出口端口。
