渐进式空腔泵(Progressive Cavity Pump)是一种通过螺旋形转子和弹性定子之间的密封腔体运动实现流体输送的容积式泵。其核心结构由金属转子和橡胶或合成材料制成的定子组成,转子在定子内作行星回转运动,形成连续推移的密封腔室,从而实现流体的无脉动输送。
该泵的工作原理基于几何空腔的渐进式位移。当转子旋转时,空腔从吸入端向排出端轴向移动,每个完整旋转周期输送固定体积的流体。这种特性使其特别适用于高粘度介质(如原油、泥浆)和含固体颗粒的混合物(最大可处理直径达80mm的固体颗粒)。
主要应用领域包括:
该泵的核心优势体现在其独特的输送特性上:流量与转速呈严格线性关系(精度达±1%),且具有自吸能力(最高可达8.5米水柱)。相较于离心泵,在输送粘度超过1000cP的介质时能效提升可达40%以上。英国机械工程师学会IMechE的研究报告指出,这类泵在非牛顿流体输送领域具有不可替代性。
progressive cavity pump(螺杆泵)是一种通过螺旋结构实现流体输送的机械装置,其核心特点和工作原理如下:
