产品用途:D型单吸多节段式离心水泵,供输送不含固体颗粒的清水及物理化学性质类似于清水的液体,液体温度不超过80摄氏度,适合于矿山、工厂及城市给排水用。性能范围:流量Q:6.3-450立方米/h扬程H:22-650m工作条件:供输送不含固体颗粒的清水及物理化学性质类似于清水的液体,液体温度不超过80摄氏度,适合于矿山、工厂及城市给排水用。
水泵的性能参数与简介:D.DG型泵系卧式、单、分段式多离心泵,吸入口为水平方向,吐出口为垂直向上。泵的进水段、中段、出水段等泵壳体部分通过拉紧螺栓联结成一体,并根据泵的扬程选择泵的数。 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数而定,轴上零件通过平键和轴螺母坚固使之与轴联为一体。整个转子由两端滚动轴承和滑动轴承支承。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,并且在泵端安装有平衡盘磨损指示器,以监视平衡盘磨损情况。 泵的进水段、中段、出水段之间的密封面均采用密封胶或"O”形圈密封,转子部分和固定部分之间装有密封环和导叶套等进行密封,当密封环和导叶套的磨损程度已影响泵的工作性能时应及时予以更换。 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 。泵的各种密封元件装在密封腔内,腔内要通入一定压力的水,起水封、水冷、或水润滑的作用,在轴封处装有可更换的轴套,以保护泵轴。 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型泵可采用滑动轴承、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。配套电机:电机常归配置为Y系列电机。对含有可燃易爆气体的矿井下运行的泵,必须采用防爆电机并要求具有相应的防护等和防爆标志。
