产品概述
DG型锅炉给水泵为卧式多级单吸节段式离心泵,泵壳可在轴线处轴向拆开,DG85-80×8型泵吸入口垂直向上,吐出口垂直向上,与轴心线垂直。从驱动端方向看,水泵旋向为顺时针方向,根据用户需要也可生产逆时针方向旋转的,用户可在定货时特别提出。
产品特点
DG型锅炉给水多级泵的吸入口、吐出口均垂直向上,转子轴向力由平衡盘来平衡。轴封可为填料密封,也可为机械密封。转子的支承仅DG85-80、DG85—67、DG155—67采用滑动轴承,稀油润滑,其它泵均采用滚动轴承。旋转方向:从电机端看,泵为顺时针方向旋转。主要零件材质:泵过流部件除DG85-80、200DG43材质为铸钢外,其余泵材质均为铸铁。成套范围:成套供应泵、电机、止回阀、闸阀、公用底座或本身底座。
