美国尼科NICO进口单级双吸管道泵又被称为中开泵,叶轮安装在泵壳内,并紧固在泵轴上,泵轴由电机直接带动。泵壳中央有一液体吸入与吸入管连接。液体经底阀和吸入管进入泵内。泵壳上的液体排出口与排出管连接。当泵的转速一定时,其压头、流量与叶轮直径有关。主要的应用领域为液体输送、自来水厂、工业供水、市政供水等主要的领域,

1.结构紧凑外形美观,稳定性好,便于安装。
2.运行平稳优化设计的双吸叶轮使轴向力减小到低限度,且有优异水力性能的叶型,离心泵泵壳内表面及叶轮表面具有抗汽蚀性能。
3.轴承选用SKF及NSK轴承保证运行平稳,噪音低,使用寿命长。
4.轴封选用机械密封或填料密封。能保证8000小时运行无泄漏。
5.离心泵安装形式装配时不需调整,可根据现场使用条件。分立式或卧式安装。
6.加装自吸装置,可实现自动吸水,即不需安装底阀,不需真空泵,不需倒灌,离心泵可以启动。
1.本型泵的吸入口与吐出口均在水泵轴心线的下方,与轴线垂成水平方向.检修时无需拆卸进出口水管及电机.从转动方向看去,水泵为顺时针方向旋转/根据用户需要亦可改为逆时针方向旋转。
2.泵主要零件有:泵体,泵盖,叶轮,轴,双吸密封环,轴套等。
3.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。
4.经过静平衡校验的叶轮,用轴套的两边的轴套螺母固定在轴上,其轴向位置可通过轴套螺母进行调整。
5.泵轴由两个单列向心球轴承支承。轴承装在轴承体内,安装在泵体两端,用黄油润滑。
6.双吸密封环用以减少水泵压力室的水漏回吸水室。
7.泵通过弹性联轴器由电动机直接传动。必要时亦可用内燃机传动。
8.轴封为软填料密封,根据用户需要可采用机械密封结构。
主要用途:适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程 。
