多级榆树管道增压泵工作原理
当电机带动轴上的叶轮高速旋转时，充满在叶轮内的液体在离心力的作用下，从叶轮中心沿着叶片间的流道甩向叶轮的四周，由于液体受到叶片的作用，使压力和速度同时增加，经过导壳的流道而被引向次一级的叶轮，这样，逐次地流过所有的叶轮和导壳，进一步使液体的压力能量增加。将每个叶轮逐级叠加之后，就获得一定扬程。
GDL型立式多级管道泵是90年代zui5 新泵型。zui大优点节能、占地面积小、安装方便、性能稳定、外套用1Cr18Ni9Ti优质不锈钢,轴封用耐磨机械密封,无泄漏、使用寿命长。以水力平衡解决轴向力,因而泵运转平稳、低噪音,安装条件优于DL型泵,可以简便安装于任一段水平管路中间。水力效率高，性能范围广，进出口直径25-100毫米，流量每小时2～72吨，扬程25～150米，共9个系列70多个规格，完全能满足高层建筑、深井矿等的给排水及消防设施需要,是各大行业冷热水或一般介质、理化性质类似于水等液体输送的zui的佳泵型。
