上锐DG卧式多级泵产品概述:
上锐DG卧式多级泵可供输送清水或物理化学性质类似于清水的液体,适用于中、低压锅炉或次高压锅炉给水,也适用于工厂或城市高压给排水。输送介质温度为-20℃~150℃,进口允许压力小于0.6MPa。
DG该系列泵采用了国家推荐使用的高效节能产品的水力模型。具有效率高、性能范围广、运转安全和平稳、噪音低、寿命长、安装维修方便等优点。
DG卧式多级泵结构特点:
DG型卧式多级泵进、出水口均为垂直向上,通过拉紧螺栓将泵的进水段、中段、出水段、轴承体等泵壳体部分联结成一体。根据泵的扬程选择泵的级数。
该系列泵转子部分主要由及安装在轴上的叶轮、轴套、平衡盘等零件组成,其中叶轮的数量根据泵的级数而定。轴上零件用平键和轴螺母紧固使之与轴联为一体。整个转子由两端滚动轴承或滑动轴承支承。轴承按型号不同而定,均不承受轴向力,其轴向力由平衡盘平衡。泵在运行中允许转子在泵壳中轴向游动,不能采用向心轴承。滚动轴承用油脂润滑、滑动轴承用稀油润滑,并用油环进行自润滑,循环水冷却。
泵的进水段、中段、出水段之间的密封面均采用二硫化钼润滑脂密封,转子部分与固定部分之间装有密封环、导叶套等进行密封,当密封环和导叶套的磨损程度已影响泵的工作性能时应予更换。
轴的密封形式有机械密封和填料密封两种。泵采用填料密封时,填料环的位置安放要正确,填料的松紧程度必须适当,以液体能一滴一滴渗出为宜。泵各种密封元件装在密封箱内,箱内要通过一定压力的水,起水封、水冷或水润滑的作用。在轴封处装有可更换的轴套,保护泵轴。次高压泵一般采用滑动轴承、稀油润滑结构,DG85-67、DG155-67型泵可采用滑动轴承、稀油润滑,也可采用滚动轴承、干油润滑结构,其余型号均采用滚动轴承,干油润滑结构。中、低压泵的主要零件材料一般采用优质铸铁,次高压泵主要零件采用铸钢或不锈钢。该系列泵通过弹性联轴器由原动机直接驱动,从原动机方向看,泵为顺时针方向旋转。
