CWF-S型船用卧式封水泵

 
一、概述 General

CWF-S系列船用卧式封水泵专为挖泥船的泥浆泵的轴封保护而设计。其原理是封水泵将高压清洁水注入泥浆泵的轴封与叶轮室之间,阻挡泥浆泵输送的泥浆、砂石等固体颗粒进入轴封腔,以保证泥浆泵正常可靠地工作。该系列泵也适用于船舶作压载泵、舱底泵、冷却泵消防泵及总用泵等。可输送温度不高于80℃的海水、淡水及无腐蚀性的其他液体介质。
从驱动端看泵为顺时针方向旋转。
The CWF-S series marine horizontal water sealing pump is suitable to the protectiom pump on dredger where it is used to seal the water.It is also suitable to the bilge pump,colling pump and fire pump on boats.It may be used to deliver the sea water,fresh water or other non-corrosive liquid medium lower than 80℃.
The pump rotates anticlockwise viewed from motor.
