进口立式双吸离心泵

一、进口立式双吸离心泵产品概述

美国尼科NICO进口立式双吸离心泵（原来也称中开型），使用双吸式叶轮，并且泵可以中间剖开，故称为双吸中开式离心泵。美国尼科NICO结合用户使用习惯和使用难点优化之后研发的泵种。供抽送清水或物理化学性质类似于清水的其它液体之用。要求被输送液体温度≤80℃。标配填料密封，可选配机械密封。因其可以中间剖开的特性，检修维修十分方便。深受广大用户的喜爱。第二代水力模型更优按API610 BB1结构化工系列单级双吸、水平中开式离心泵，温度范围:<80℃,底脚支撑，油润滑，效率更高，可供广大用户比较选择。高温系列、单级双吸水平中开离心泵;温度范围: 80~150℃，温度>120℃采用中心支撑。

三、进口立式双吸离心泵特点

本型泵的吸入口与吐出口均在水泵轴心线下方，水平方向与轴线成垂直位置，泵壳中开，检修时无需拆卸进水、排出管路及电动机(或其他原动机)。从联轴器向泵的方向看去，水泵为逆吋针方向旋转。如根据用户订货需要也可改为顺吋针旋转。

本型泵的主要零部件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承等。

泵体与泵盖构成叶轮的工作室，在进出水法兰上制有安装真空表和压力表的管螺孔，进出水法兰的下部制有放水的管螺孔。

叶轮经过静平衡校验，用轴套和两侧的轴套螺母固定，其轴向位置可以通过轴套螺母进行调整，叶轮的轴向力利用其叶片的对称布置达到平衡，可能还有一些剩余轴向力则由轴端的轴承承受。

泵轴由两个单列向心球轴承支承，轴承装在泵体两端的轴承体内，用黄油润滑，双吸密封环用以减少水泵压水室的水漏回吸水室。

水泵通过联轴器由电动机直接传动。

轴封为软填料密封，为了冷却润滑密封腔和防止空气漏入泵内，在填料之间有水封环，水泵工作时小量高压水通过水封管流入填料腔起水封作用。

九、进口立式双吸离心泵说明

●为清水常规配置：为特殊介质或特殊工况的选配，高效节能双吸泵技术优势

●优势一高效率：引进国内外最优秀水力模型，采用CFD计算流体动力学分析方法，针对性地进行优化分析改进;性能指标超越行业水平，达到先进水平，最高效率突破92%。

●优势二低脉动：采用两半叶轮叶片交错布置结构，从而改变叶频(叶片通过泵体隔舌频率)，使得液流脉冲降低(约降低扬程的1%。~4%o)，液流更加平稳，效率更高、振动更小、运行更加平稳可靠。

●优势三低汽蚀余量：叶片进口边形状采用凸弧形优化设计，增加液流进口过流面积，降低进口流速，使得进口边压力增加，从而提高汽蚀余量。叶片头部采用翼型流线设计，使得液流冲击损失减少，漩涡减少，不但提高了最高点效率值，同时使得高效区更加宽广，压力分布均匀，汽蚀性能更佳。

●优势四高可靠性：高扬程泵采用双蜗壳设计，泵体、泵盖均设置加强筋，并采用ANSYS力学分析软件优化结构，泵壳具有很高的强度，轴承跨距短，轴加粗设计，使得转子运转时扰度小，稳定可靠。所有叶轮均做6.3级静平衡试验，整个转子按API610标准做2.5级动平衡试验。主轴采用不接触液体的全密封式设计，轴承部件设置唇形油封+V型密封圈组合密封结构，具有优秀的防漏油、防灰尘、防水、防湿气功能。

●优势五强适应性：

泵高效区宽，能更大范围满足用户要求;另外，我们采取一泵两轮的叶轮配置方式使得泵具有非常好的可选性，能绝大部分保证用户的工况点都能选到高效范围。

泵进、出口法兰可按照GB、ISO、DIN、BS、ANSI等标准加工。

泵壳流道：可进行超滑节能涂层、耐磨耐腐涂层等选择。输送高温介质可采用CPS-R型结构，泵采用中心支撑、水冷轴承体。

轴封系统：可实现填料密封、单端面密封互换，也可按用户要求配置集装式机封、双端面机封以及配置AP1682标准的冲洗系统。

轴承润滑系统：可采用脂润滑或稀油润滑供灵活选择。

轴承冷却系统：可根据介质温度高低选择自然冷却或水冷却轴承体。

远程监控：轴承体设置测温、测振等监测接口，可方便实现远程监控。

●优势六高通用化：除泵体、泵盖、叶轮等少数零件外，其余均采用模块化设计，实现了零件的标准化，同轴系的轴承部件、密封部件、轴套、挡套等均可实现互换，方便实现泵的量产。
