生的誤差，在用圓螺母和彈性墊圈壓緊轉(zhuǎn)子時須將彈性墊圈壓至極限點，然后旋轉(zhuǎn)180°松開圓螺母。

  1、檢查水泵和電機應無損壞；

  2、混凝土基礎應牢固，表面光滑平整；

  3、把地腳螺栓插入底座上的螺孔，把泵放在基礎上，用水平儀在軸端或出口端調(diào)整水平，在泵腳和基礎靠近地腳螺栓處必須墊墊塊；

  4、泵調(diào)整好水平后，給地腳螺栓灌漿，堅固后均勻地擰緊地腳螺栓，并重新調(diào)整水平，然后給底腳灌漿；

  5、校正電機與水泵軸的同心度，使兩軸成一直線，兩聯(lián)軸器外圓上的不同心度允差為O.1毫米，端面間隙沿圓周上的不同心度允差為0.1毫米，端面間隙沿圓周的不均勻允差O.3毫米(連接進出水管路后再分別校核一遍，仍符合上述要求)；

  6、在檢查電機轉(zhuǎn)向與水泵的轉(zhuǎn)向一致后，裝上聯(lián)軸器的聯(lián)接柱銷；

  7、不要把泵本身作為管路支撐點，管路應在泵的附近設可靠支撐。

  以上為不帶底座的水泵機組的安裝方法。

  對于配帶公共底座的泵，基礎與底座之間保留4～5毫米的間隙，用調(diào)整螺釘精確地調(diào)整機組并在聯(lián)軸器處對中。其安裝原則與不帶公共底座的機組相同。

1、起動：

1)、起動前的檢查：

a)．泵或底座是否與基礎緊固；

tion of 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.
