低转速离心泵产品概述
ISGD型低转速离心泵系在ISG型基础上并参照IS型离心泵之性能参数,根据管道式离心泵的独特结构组合设计制造。该产品采用国内水泵专家提供的先进水力模型,高效节能,性能可靠,深受国内外客商的赞益。
低转速离心泵产品特点
ISGD型低转速立式离心泵是在ISG型立式离心泵基础上配用低转速电机,大幅度降低了运行噪音,成倍延长易损件命名用寿命,适用于空调循环及采暖循环和各种循环系统末端增压。创新设计的立式结构使其占地面积和占用空间更少,使用更方便。
ISGD型低转速立式离心泵:主要用于空调系统冷冻水,冷却水循环及末端增压,城市供热系统局部或末端增压循环,及城市建筑消防系统局部恒压及各种空调热水锅炉配套。
低转速离心泵工作条件
ISGD型电机0.75kw以上泵系统高工作压力为1.6MPa即泵吸入口压力+泵扬程≤1.6MPa,泵静压试验压力为2.5MPa,0.75kw以下泵系统高工作压力为0.8MPa。低转速离心泵订货时请注明系统工作压力,泵系统工作压力大于1.6MPa时,应在订货时另行提出,以便在制造时泵的过流部分和联接部分采用铸钢材料。ISGD低转速离心泵制泵介质为冷热水或物理化学性质类似于水的液体,介质温度不超过120℃。

1、安装前应仔细检查泵体流产内有无硬质物,以免运行时损坏叶轮和泵体。
2、安装时管路理量不允许加在泵上,以免使泵变形,影响正常运行。
3、拧紧地脚螺栓,以免起动时振动对泵性能产生影响。
4、在泵的进出口管路上安装调节阀,在泵出口附近安装压力表,以控制泵在额定工况内运行,确保泵的正常使用。
