产品简介

Product Introduction


    该系列泵系卧式单吸多级分段式离心泵,采用了节能产品的水力模型,完全按MT/T114-2005《煤矿用多级离心泵》设计和生产,按JB/T1051-93《多级清水离心泵  型式及基本参数》设计。该泵具有性能范围广和平稳、噪音低、寿命长、安装维修方便等优点。

  D、DF、DY、MD系列自平衡型离心泵,分为单吸多级机构和双吸多级机构,是我公司在D型单吸多级离心泵基础上研制多年,开发成功的产品。该系列产品气蚀性能好、运行平稳、易损件少、可靠性大大提高,用户维护成本大大降低,从而降低泵的寿命周期成本。 

  可供输送不含固体颗粒(磨料)、不含悬浮物的清水或物理化学性质类似于清水的其它液体之用。也可通过改变泵的材质(或泵过流部件的材质)、密封形式和增加冷却系统用于输送热水、油类、腐蚀性或含磨料的介质等。泵允许进口压力不大于0.6MPa 。 



应用领域

Applications Areas


1) D型:D型泵供输送不含固体颗粒、温度低于80℃的清水或物理化学性质类似于清水的液体。适合于矿山、工厂和城市给排水工程之用。

2) MD型: MD型用于输送颗粒含量≤1.5%,粒度≤0.5mm,温度为-20~80℃的中性矿井水及其他类似的污水。

3) DF型:DF型泵供输送不含固体颗粒、温度为-20℃~105℃的腐蚀性液体,泵进口允许压力小于0.6MPa。用户可根据输送介质的名称、浓度、比重、使用温度及泵进口压力等合理选用泵的材质、密封形式、泵的结构和确定电机的容量等。

4)DY型:用于输送不含固体颗粒、温度为-20~105℃、粘度小于120厘的油类和石油产品。



产品特点

Product Feautres


    D、MD、DF型泵系卧式、单吸、分段式多级离心泵。D型泵的吸入口为水平方向,吐出口为垂直向上;DF、MD型泵的吐出口和吸入口(如DF155-30的吸入口为水平方向)基本上为垂直向上。用拉紧螺栓将泵的吸入段、中段、吐出段、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轴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成为一体。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,不能采用向心球轴承。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,箱内要通入一定压力的水,起水封、水冷或水润滑作用。在轴封处装有可更换的轴套,保护泵轴。

    泵在运行中允许转子在泵壳中轴向游动,该型泵一般采用滚动轴承、干油润滑结构(D85-67、D155-67型泵可采用滚动轴承、稀油润滑结构,也可采用滚动轴承、干油润滑结构)。

    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。
