二、产品概述
 
    DQLB型便拆立式管道离心泵是在ISG型泵的基础上开发成功的一种结构新颖,技术先进的产品。
   
    该立式泵告别是在整体结构上进行大胆突破设计。采用独立轴承体、泵轴支撑,解决了原来立式泵靠电机轴承支撑的不足之处;采用优秀水力模型的叶轮,消除了原立式泵轴向力大的不足之处;电机采用Y系列标准通用电机,解决原立式泵加长轴电机配套更换难的问题;同时100%的便拆结构,解决了更换大功率水泵的轴承、机械密封、叶轮、泵轴的难题。
   
    该泵与国内同类产品相比,具有运转更平稳、使用寿命长、配套更方便、维护保养更轻松等等,无可代替的优点。在立式泵系列产品中属国内前列,各项技术居国内领先,是替代ISG型立式泵、IS型离心泵、S型双吸泵等常规各种离心泵的最理想产品。
 
三、工作条件
 
1、泵系统最高工作压力为1.6MPa,即泵吸入口压力+泵扬程≤1.6MPA(泵扬程工作压力大于1.6MPa时应在订货另行提出,以便在制造时泵的过流部件和联接部件采用铸钢)。 2、输送介质为清水或物理化学性质类似清水的其它液体。(输送介质带有细小颗粒的应在订货时另行说明,以便装配耐磨式机械密封)。 3、环境温度≤40℃,海拔高度≤1000m,相对湿度≤95%
