详细内容
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。
DFG管道离心泵产品特点
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。
