DL立式多级离心泵是采用推荐使用的 节能产品IS型泵的水力模型,为立式多级多节段式结构。螺杆把进水段、中段、出水段夹紧联成一体。水泵每一级装一个叶轮、一个导水叶。轴向力采用水力平衡法解决,残余轴向力由球轴轴承承受,用油脂润滑。轴封采用软填料或机械密封。产品执行JB/T2727-93《立式多级离心泵型式与基本参数》标准,主要供吸送稀释的、清洁的、不腐蚀的、不爆炸的清水及物理化学性质类似水的不含固体颗粒或纤维的液体。
适用范围
广泛应用于高层建筑的消防、生活供水以及空调机组循环、冷却水输送。
结构特点
1、水力模型:效率高,性能范围广。
2、结构运行可靠:取消了平衡鼓,其轴向力采用水力平衡,彻底解决了平衡鼓易锈蚀、易咬死、易磨损的问题, 了运行更加可靠。
3、较少的运行、维修费用:采用质量可靠的机械密封,耐磨损、无泄漏、使用寿命长,故障率低,具有较少的运行维修费用。
4、运行平稳,噪音低:采用低转速电机,使泵运行平稳,噪音低。
5、立式结构,占地面积小。
