生的误差，在用圆螺母和弹性垫圈压紧转子时须将弹性垫圈压至极限点，然后旋转180°松开圆螺母。
1、检查水泵和电机应无损坏；
2、混凝土基础应牢固，表面光滑平整；
3、把地脚螺栓插入底座上的螺孔，把泵放在基础上，用水平仪在轴端或出口端调整水平，在泵脚和基础靠近地脚螺栓处必须垫垫块；
4、泵调整好水平后，给地脚螺栓灌浆，坚固后均匀地拧紧地脚螺栓，并重新调整水平，然后给底脚灌浆；
5、校正电机与水泵轴的同心度，使两轴成一直线，两联轴器外圆上的不同心度允差为O.1毫米，端面间隙沿圆周上的不同心度允差为0.1毫米，端面间隙沿圆周的不均匀允差O.3毫米(连接进出水管路后再分别校核一遍，仍符合上述要求)；
6、在检查电机转向与水泵的转向一致后，装上联轴器的联接柱销；
7、不要把泵本身作为管路支撑点，管路应在泵的附近设可靠支撑。
以上为不带底座的水泵机组的安装方法。
对于配带公共底座的泵，基础与底座之间保留4～5毫米的间隙，用调整螺钉精确地调整机组并在联轴器处对中。其安装原则与不带公共底座的机组相同。
1、起动：
1)、起动前的检查：
a)．泵或底座是否与基础紧固；

rotation;
3. Heat the deep groove ball bearing and
fit it onto the shaft (sleeve) ;
4. For compensate differences in thermal
expansion between pump shaft and the components fitted on it. Tension the rotor
parts elastically with groove nut and disc spring. For this purpose tension the
disc spring to blocking point and then undo the grooved nut again by half a turn
180℃.
1. Chech whether the pump and the motor are
in good condition;
2. The concrete foundation must have
been set hard and the surface must be smooth and flat;
3. Loosely insert the foundation bolts
in the baseplate. Position the pump set on the pump set on the foundation and
align using a spirit level placed on the shaft or discharge nozzle. Shims must
always be fitted to the left and right of the foundation bolts in close
proximity to the bolts, between the baseplate or foundation frame and the
foundation itself.
4. After alignment, grout in the foundation bolts using
cement mortar. When the mortar has been set hard, uniformly tighten up the
bolts and re- cheek the alignment. Grout in the baseplate (non- shrinking
mortar is highly recommend-ed), ensuring that no cavities remain.
5. After the eoneret solidifed, again
correct the coaxial degree in the exeircle of the two couplings, the error of
the correction is not more than 0.1mm, the allowable error of the inhomogeneous
degree of the endfaee clearance along the circle is 0.3mm, Re-inspect the correct prieision after
tightening the foot unts, finally, pour
eoncret fuly nuder the foot of the pump and the motor except the around of the
wedge shaped cushion.
6. After cheek the rotary direction of
the motor which is now in keeping with that of the pump, you can install the
connecting parallel pin of the coupling.
7. The inlet pipe and outlet pipe should
be supported by a brasket instead of the pump easing.
Above all the mentioned methods and requirements
are suitable for the pump set without common bedplate.
