NS系列抽沙泵为单级、单吸、悬臂式离心泵，按出口直径分为500mm、450mm、400mm、350mm、300mm、250mm、200mm、150mm等几大系列多种规格。产品耐磨性能好，型号多，方便选型，可满足于流量大，扬程高的环境。该泵在水力设计、结构设计方面有创新，叶轮叶片数量可以根据不同的工况环境改变，适合输送含大小固体颗粒的泥沙，强磨蚀的砂浆、灰浆、尾矿浆、矿渣等，输送均匀的粉状固液混合浓度可达到60%，是比较理想的抽砂、送砂设备，用户可根据实际工况采用单机或多机串联运行的方式达到远距离施工的目的。
广泛应用于江河湖海、水库抽砂抽矿砂、围海造地、吹沙填海，电力粉煤灰输送、冶金行业输送尾矿，水力、电力、矿山、冶金、煤炭、建材、化工、食品及污水处理等。
产品特点及优势：
1、泵体采用内外双层金属结构，泵壳为垂直中开，安全性能高，出水口位置按45度间隔旋转安装。
2、过流部件采用抗强磨蚀的高鉻耐磨合金铸造，具有高效、节能、耐磨、运行可靠等特点。
3、独特的密封结构，盘根使用寿命长。轴封根据不同的工况分为：副叶轮轴封、填料轴封和机械密封。
4、采用闭式叶轮，耐磨性好，泵效率高。
5、泵的传动方式有直联传动和皮带传动两种方式，从原动机方向看，泵为顺时针方向旋转。
6、可通过调节叶片数量和叶轮直径输送含有少量较大颗粒的混合物。
7、吸深能力强，可达到水下35米深。
8、扬程大，个别型号扬程可达100米。
9、流量大，最大流量可达2000立方/小时。
10、型号多，方便根据不同工况环境选型。

使用注意事项：
1、起动：泥沙泵起动前应按下列步骤检查整个机组。
⑴泵应安放在牢固基础上，以承受泵的全部重量，消除振动，拧紧全部地脚螺栓。
⑵管路阀门应有自己的支撑架，且应支撑牢固。泵法兰处有密封点，拧紧连接螺栓时应注意，不能过紧，以免损坏密封点。
⑶用手按泵转动方向转动轴，轴转动时，不应有磨擦，否则调叶轮间隙。
⑷检查电机转向，要保证泵按泵体上所标出的箭头方向转动。绝对禁止反转。
⑸直联传动时，泵轴和电机轴应精确对中，皮带传动时泵轴和电机轴应平行，并调整槽轮位置，使其与槽带垂直，以免引起剧烈的振动和磨损。
⑹轴封检查：检查轴封水量，水压是否合适，调节填料压盖压紧螺钉，以调节填料的松紧程度，调节轴封水，从填料压盖处的泄漏量一滴滴渗出为好，填料太紧，轴套易发热，同时耗费功率，填料太松则液体渗漏量太大。轴封水压一般高于泵出口压力35KPa，轴封水量一般建议按不同型号在0.15L/S-2.1L/S。装有机械密封的泵，在开泵前须先接通轴封水。
2、运转：
⑴运转中应定期检查轴封水的压力和流量，及时调节填料压盖或更换填料，以保证始终有少量的清洁水通过轴。
⑵定期检查轴承组件运转情况，开车前需往轴体注入20或30号润滑油，并在交管接头接好冷却水（18.5kw以下不须冷却水）。轴承润滑油量要适当，清洁，要定期添加或更换润滑油。
⑶泵性能随着叶轮与护板间隙的增大效率降低，故应及时将叶轮向前调整，以保持一定间隙，使泵能保持在高效运行，当泵磨损到不能满足系统需要时，应更换易损件，定时拆检泵，估计易损件寿命，以免承磨件失效时对系统产生严重后果。
3、停泵：
停泵前应尽可能使泵抽送一会清水，以清洗流经泵内的渣浆，然后依次关闭泵、闸门、轴封水和轴承体的冷却水。
泥沙泵维护保养：
要使泵能安全运行，寿命长，必须注意日常的维护，维护保养应注意以下几个方面：
1、轴封的维护：
要定期检测密封水压和水量，要始终保持少量清洁水沿轴流过，定期调填料压盖，检查填料并定期更换填料。轴封水压，轴封水量应符合上述（轴封检查）要求。装有机械密封的泵，长期不使用时，机械密封部件应加注满N46号机油，以防止机械密封部件生锈及内部橡胶件失效。
2、叶轮的调节：
为了保证泵高效运转，就必须及时调整叶轮与前护板的间隙，调节叶轮间隙时首先停泵，松开压紧轴承组件的螺栓，拧调整螺栓上的螺母，使轴承组件向前移动，同时用手转动轴按泵的转动方向旋转，直到叶轮与前护板摩擦为止，将前面刚拧紧的螺母放松半圈，再将调整螺栓上前面的螺母拧紧，使轴承组件后移，此时叶轮与前护板间隙在0.5-1mm之间。调整后，在再次起动前须重新检查叶轮转动是否正常，轴承组件压紧螺栓是否拧紧，然后再起动泵。
3、轴承润滑：
轴承组件在装配时，若装配正确，润滑油适量，维修及时，运转寿命会较长，维修人员应定期检修轴承组件，检查轴承组件及润滑油的情况，在运转中须定期添加或更换润滑油，间隙时间及注入的量与泵的转速、轴承规格、连续工作时间、泵的停开次数，周围环境和运转温度等许多因素有关，因此须逐渐积累经验，合理及时的加润滑油。
4、备有泵应每周将轴转动1/4圈，以使轴承均匀的承受静载荷和外部振动。 |
