美国尼科NICO进口自吸式屏蔽泵是一种电动机和水泵一体化结构的泵类产品工艺,吸入配管内未充满液体时,泵通过自动抽气作用扬液,适应于从地下容器中抽提液体。可靠性能高,没有轴密封,做到时无泄露,因其电机自身低噪音,加之屏蔽泵低故障率安全环保和维护成本等优点。进口自吸式屏蔽泵许用压力为1.0Mpa、2.0Mpa。它除了具有普通屏蔽电泵的特点外,其突出特点是具有自动抽气功能,管路吸上高度可达5m,适用于抽送地下罐和槽车罐中的不含颗粒的液体。
公称通径:40-300mm
流量范围:5-42(m3/h)
扬程范围:10-50m
功率范围:0.37-30KW
转速范围:1450-2900r/min
温度范围:-20℃~350℃
工作压力:1.0Mpa-2.0Mpa
泵体材质:WCB、304、316
1、电机与水泵一体化结构,水泵与电动机为同轴连接;
2、电动机定子内侧和转子外侧具有屏蔽套,屏蔽套内侧和泵内连通;
3、安装方式分卧式和立式两种
4、电动机取消了冷却风扇,通过定子与转子之间循环介质对电动机进行冷却,同时采用电动机机座表面冷却。
1、电机与泵一体化结构,全部采用静密封,使电泵无泄漏;
2、全封闭、无泄漏结构可输送有毒有害液体物质;
3、采用屏蔽式水冷电机和取消了冷却风扇使该泵低噪声运行,适用于对环境噪声要求高的场合;
4、采用输送介质润滑的石墨滑动轴承,使运行噪声更低且无需人工加油,降低了维护成本;近几年轴承材质又增加有碳化硅SIC,超硬等,使用寿命优于石墨轴承。
5、立式结构可像阀门一样安装于管路上,安装方便快捷,且维修时只需将电机与叶轮抽出即可,无需拆除管路。
6、可以配合减震器或减震垫安装运行,使电泵在运行时噪声更低。
进口自吸式屏蔽泵具体形式吸入配管内未充满液体时,泵通过自动抽气作用扬液,适应于从地下容器中抽提液体。
1、输送普通物料的基本型;
2、输送易汽化物料的逆循环型及逆向加压型;
3、输送高温物料的高温分离型,通常温度在350度以下;
4、输送有颗粒的物料的泥浆型;
5、输送高熔点物料的高熔点型;
6、输送物料液位低于泵吸入口的自吸型,自吸高度应低于5米。
一、民用

1、进口自吸式屏蔽泵与电机连接,应各自校准水平并保证两者同轴后方可装上联轴器,否则,将会造成机件的损坏。
2、因自吸屏蔽泵属于容积泵,每转的排量固定,一旦上一道工序停止工作而泵仍在继续工作,泵的压力会升高,将导致密封泄露,机件损坏等事故发生,为此,在使用时要才有有效的预防措施。一是,上下工序间应连锁,当上下工序停机时,同时停止泵的工作;二是,在输出管理装安全阀及安全回流系统,若,超压自动卸载。
3、如果对自吸屏蔽泵加控制阀,只能装在泵的进口管路上,出口管路上不宜装控制阀,容易造成失误超压。
以上操作完毕后,还应进行检查,包括机件坚固、电气接线等,然后,进行通电试运转,如发现异常,应停止检修,待一切正常后才能交付使用。
