| 详细介绍：
一、DFG立式管道循环泵概述
DFG（DFRG）系列单级单吸立式管道离心泵为直联式管道泵结构，叶轮安装于电机加长轴上，具有运行平稳结构简单、维护检修简便、安装方便及占地面积省（与普通卧式泵比占地面积节省30%以上）等特点；产品符合GB/T5657-1994《离心泵技术条件(III)类》标准；可输送介质温度不超过105℃的清水或物理化学特性类似于清水的其他液体。
二、DFG立式管道泵产品特点
1、高效节能：采用CFD计算流体动力学，分析计算出泵内压力分布和速度分布关系、优化泵的流道设计，确保泵有高效的水力形线，提高了泵的效率。
2、安装、维修方便：立式管道式结构，泵的进出口能象阀门一样安装在管路的任何位置及任何方向，安装维修极为方便。
3、运行平稳，安全可靠：电机轴和水泵轴为同轴直联、同心度高，运行平稳，安全可靠。
4、不锈钢轴套：轴的机封位置是相对易被锈蚀之处，直联式泵轴一旦被锈蚀，易造成机械密封失效。DFG（DFRG）泵此处采用镶配不锈钢轴套，避免锈蚀发生，提高了轴寿命，降低了运行维护成本。
5、轴承：泵所配电机中，Y（Y2）280以下轴伸端轴承（包括Y180以下风叶端轴承）采用封闭式轴承，正常使用时，免电机轴承的维护保养。
6、机封：机械密封基件一般选用橡胶波纹管结构，将传统机械密封中轴上密封由O形圈的线密封改为橡胶件的两道面密封，在清水介质时提高了密封效果。
三、DFG立式管道循环泵工作条件
流量: 2～1400m3/h 扬程：5～130m
系统最大工作压力：≤1.6MPa 工作温度：普通型（DFG）-15℃ ～+ 80℃
热水型（DFRG）+80℃～ +105℃ 配套电机：绝缘等级：B级或F级
防护等级：IP44或IP54 环境温度：≤+40℃
电机类型：Y2或YX3
