SMT 16B - 螺杆泵
产品介绍 > SMT 16BSMT 16B中低压无噪音螺杆泵
SMT16B 泵是一款工业用三螺杆泵，适合低中压（40 巴）下使用。SMT16B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。SMT16B泵是一款装配于泵体内的灌液泵。泵体和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。SMT泵可配内置或外置式泄压安全阀。SMT16B 与 SMT 泵相比，其螺杆更短，适用于空间有限的应用场景。
