14、拆下（xià）密封體、軸套；

    15、用橡膠榔頭輕輕（qīng）敲擊葉輪輪轂將葉輪從軸上退出：

    16、拆下另一端軸套、密封體，拆下聯軸器，拆下軸承體：

    17、鬆開彈性擋（dǎng）圈（quān），退出（chū）深溝軸承。

    裝配順序按拆（chāi）卸順序相反進行，但必（bì）須注（zhù）意：

    1、安裝轉子時必須將軸放穩，所有的配合螺紋和間隙配合處都必須清洗並塗上裝配粘合劑：

    2、裝帶有間隙配合的葉輪時，應注意葉輪的轉（zhuǎn）向：

    3、深溝軸承須加熱後裝上軸(軸套)：

    4、為補（bǔ）嚐泵軸與軸上零件之間由於（yú）熱膨脹產生的（de）誤差，在（zài）用圓螺母和彈性墊圈壓緊（jǐn）轉（zhuǎn）子（zǐ）時須將彈性墊（diàn）圈壓至極限點，然後旋轉180°鬆開圓螺母。

    1、檢查天天操B夜夜操B和電機應無損壞；

    2、混凝土基礎應牢固，表麵光滑（huá）平整：

    3、把地腳螺栓插入底座上的螺孔，把（bǎ）泵放在基礎上，用水平儀在軸端或出口（kǒu）端（duān）調整水平，在泵腳和基礎靠近地腳螺栓處必須墊墊塊：

    4、泵調整好水平後，給地腳螺栓灌漿，堅固後均勻地擰緊地腳螺栓，並重新調整水平，然後給底腳灌漿：

    5、校正電機與水（shuǐ）泵軸的同心度，使兩軸成一直線，兩聯軸器外圓上的不同心度允差為

    10. Undo and twist off the grooved nut.

    11. Remove the deep groove ball bearing with bush from the shaft.

    12. Remove bearing cover.

    13. Remove block water ring from shaft -protecting sleeve;

    14. Remove shaft seal housing;

    Pull off shaft protecting sleeve;

    15. The impeller located with sliding fit on the shaff and can normally be removed easily. In ease of difficulty,  it can be loosened by gently tapping with a plastic hammer;

    16. Remove second shaft protection sleeve complete with the shaft seal housing,  if fitted. Remove coupling half and pull off deep groove ball bearing;

    17. Pull off bearing housing. Remove eirelip and pull off deep groove ball bearing.

    Reassembly is effeeted in reverse order to; disassemlly, but must give your attention to:

    1. For assembling the rotor,  position the pump shaft securely. All fits, threads and sliding fits of the shaft must be cleaned and coated with assembly paste;

    2. Mount the impeller, which has a sliding fit. When fitting the impeller,  observe the direction 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. Check 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 |nortar. When the mortar has been set hard, uniformly tighten up the bolts and
