16、.123、将转子部件装在泵体上，调整叶轮，使其轴向位置位于两侧双吸密封环的中间后加以固定，并将轴承体压盖用固定螺钉坚固。4、装上填料，放好中开面纸垫，装上泵盖打紧螺尾锥销后，拧紧泵盖螺母，最后装上填料压盖。但不要将填料压得太紧，填料过紧会使轴套发热，耗费功率较大，也不要压得太松，过松会使液体渗漏大，水泵效率降低。5、装配完成后，用转动泵轴，应没有控碰现象，转动比较轻滑均匀却可，拆卸可按上述装配顺序相反地进行。四 安 装 要 求1、检查水泵和电动机应无损坏。2、基础尺寸应符合泵机组的安装尺寸。3、安装顺序：（1）将水泵放在埋有地脚螺栓的混凝土基础上，用调整其间的楔形垫块的方法校正水平，并拧紧地脚

17、螺栓，以防走动。（2）在基础与泵底脚之间灌注混凝土。（3）待混凝土干固后，拧紧地脚螺栓，并重新检查水泵的水平度。（4）校正电动机轴与水泵轴的同轴度。使两轴成一直线，在两联轴器外圆上的不同轴度允差0.1毫米，端面间隙沿圆周的不均匀度允差0.3毫米（在联接进出水管路及试运行后再分别校核一遍，仍应条例上述要求）。（5）在检查电动机轴向与水泵的转向相一致后，装上联轴器的联接柱销。4、进出水管路应另设支架支撑，不得借泵体支承。5、水泵与管路之间结合面，应保证良好的气密性，尤其是进水管路，必须保证严格的不漏气，并且在装置上应无窝存空气的可能。6、如水泵安装在进水位以上时，为了灌泵起动，一般可装底阀，也可采

18、用真空引水的方法。7、水泵与出水管路之间，一般需装闸阀和止回阀（扬程小于20米的可不用），止回阀装在闸阀后面。8、泵、电机安装尺寸以常用电机计算，根据用户需要或实际选用的其它电机，其安装尺寸请用户按实际计算。以上所述的安装方法是指不配带公共底座的水泵机组。安装配还公共底座的泵，用调整底座与混凝土基础之间的楔形垫铁来校正机组的水平，然后在其间灌注混凝土。其安装原则与要求，和不配带公共底座的水泵相同。 五 使 用 说 明1、起动与停止：（1）起动前，转动泵的转子，应该轻滑均匀。（2）关闭出水闸阀，向泵内注水（如无底阀则用真空泵抽吸引水），要保证泵内充满水，无空气窝存。（3）如果泵上装有真空表和压力

19、表，要关闭其与泵相连接的旋塞再起动电动机，待转速正常后现打开；然后逐渐打开出水闸阀，如流量过大，可以适当地关小闸阀进行调节；反之流量过小时，将闸阀开大。（4）均匀地拧紧填料压盖上的压紧螺母，使液体成滴状漏出，同时注意填料腔处的温升。（5）当停止水泵运转时，要先关闭真空表及压力表旋塞和出水管路上的闸阀，然后关闭电动机的电源，如所处环境的温度较低时，则应将泵体下部的四方螺塞打开，去掉剩水，以免冻裂。（6）长期停止不用时。应拆开水泵，将零件上的水擦干，在加工表面涂上防锈油保管好。2、运转：（1）水泵轴承最高温度不应超过75（2）润滑轴承用的钙基黄油的数量以占轴承体空间的1/31/2为宜。（3）填料磨

20、损时可适当压紧填料压盖，若磨损过多应加以更换。（4）定期检查弹性联轴器部件，注意电机轴承温升。（5）运转过程中，如发现噪声或其他不正常的声音时，应立即停车，检查其原因，加以消除。（6）不得任意提高水泵的转速，但可以降低转速使用，如本型泵额定转速为n，流量为Q，扬程为H，轴功率为N，降低转速不n1,降低后流量、扬程、轴功率分别为Q1，H1和N1，其相互关系，可用下列公式进行换算： Q1=( )Q H1=( )2H N=( )3故 障原 因排除方法一、泵不吸水，压力表及真空表的指针剧烈跳动1.注入的水不够；2.管路或仪表漏氯。1.再往泵内注水；2.拧紧堵塞漏气处。二、泵不吸水，真空表显示高度真空。

22、加出不管阻力来降低流量。六、泵内声音反常，泵不上水1.吸水管阻力过大；2.吸水高度过高；3.吸水处有空气吸入；4.所吸送流体温度过高；5.流量过大而发生汽蚀现象。1.清理吸水管路及底阀；2.降低吸水高度；3.检查底阀；降低吸水高度堵塞漏气处；4.降低液体温度；5.调节出水闸阀，使之在规定的性能范围内运转。七、泵振动1.泵发生汽蚀；2.叶轮不平衡；3.泵轴与电动机轴不同心；4.地脚螺栓松动。1.调节出水闸阀，使之在规定的性能范围内运转；2.叶轮校正静平衡；3.校正泵轴与电动机轴的同心度；4.拧紧地脚螺栓。八、轴承过热1.轴承内没有油；2.泵轴与电动机不在同一中心线上。1.检查并清洗轴承全；加润滑
