As the increase of the pressure difference, the contact pressure increases, the contact pressure of iso-wall thickness progressive cavity pump is larger than that of common one.
隨着壓差的增加接觸壓力相應增加,等壁厚螺杆泵比普通螺杆泵接觸壓力大;
漸進式空腔泵(Progressive Cavity Pump)是一種通過螺旋形轉子和彈性定子之間的密封腔體運動實現流體輸送的容積式泵。其核心結構由金屬轉子和橡膠或合成材料制成的定子組成,轉子在定子内作行星回轉運動,形成連續推移的密封腔室,從而實現流體的無脈動輸送。
該泵的工作原理基于幾何空腔的漸進式位移。當轉子旋轉時,空腔從吸入端向排出端軸向移動,每個完整旋轉周期輸送固定體積的流體。這種特性使其特别適用于高粘度介質(如原油、泥漿)和含固體顆粒的混合物(最大可處理直徑達80mm的固體顆粒)。
主要應用領域包括:
該泵的核心優勢體現在其獨特的輸送特性上:流量與轉速呈嚴格線性關系(精度達±1%),且具有自吸能力(最高可達8.5米水柱)。相較于離心泵,在輸送粘度超過1000cP的介質時能效提升可達40%以上。英國機械工程師學會IMechE的研究報告指出,這類泵在非牛頓流體輸送領域具有不可替代性。
progressive cavity pump(螺杆泵)是一種通過螺旋結構實現流體輸送的機械裝置,其核心特點和工作原理如下:
