DLY立式液下多级泵
添加时间：2016-07-25
概述
DLY型液下泵是一种特殊型式的多级离心泵。广泛适用于采油厂、化工厂、炼油厂、发电厂、水厂等输送各种物理或化学性能类似于清水的油类及油水混合物。
性能范围
流量：Q 6-400m3/h
扬程：H 15~600m
温度：T -40℃～+180℃
粘度：δ ≤200cst(厘沲）
特殊工况，另可设计
结构特点
该系列泵为节段剖分立式多级离心泵，电机采用立式防爆型，从电机端看为逆时针旋转。介质从底部轴向吸入，水平吐出。安装便利，极为适合户外安装作业
轴向力主要由平衡鼓承受，并设置推力球轴承平衡残余轴向力。轴封采用迷宫式节流减压，加填料密封，保证填封处无泄漏。微少的液体从溢流管排回吸液池。
