16、.123、將轉子部件裝在泵體上，調整葉輪，使其軸向位置位于兩側雙吸密封環(huán)的中間后加以固定，并將軸承體壓蓋用固定螺釘堅固。4、裝上填料，放好中開面紙墊，裝上泵蓋打緊螺尾錐銷后，擰緊泵蓋螺母，最后裝上填料壓蓋。但不要將填料壓得太緊，填料過緊會使軸套發(fā)熱，耗費功率較大，也不要壓得太松，過松會使液體滲漏大，水泵效率降低。5、裝配完成后，用轉動泵軸，應沒有控碰現(xiàn)象，轉動比較輕滑均勻卻可，拆卸可按上述裝配順序相反地進行。四 安 裝 要 求1、檢查水泵和電動機應無損壞。2、基礎尺寸應符合泵機組的安裝尺寸。3、安裝順序：（1）將水泵放在埋有地腳螺栓的混凝土基礎上，用調整其間的楔形墊塊的方法校正水平，并擰緊地腳

17、螺栓，以防走動。（2）在基礎與泵底腳之間灌注混凝土。（3）待混凝土干固后，擰緊地腳螺栓，并重新檢查水泵的水平度。（4）校正電動機軸與水泵軸的同軸度。使兩軸成一直線，在兩聯(lián)軸器外圓上的不同軸度允差0.1毫米，端面間隙沿圓周的不均勻度允差0.3毫米（在聯(lián)接進出水管路及試運行后再分別校核一遍，仍應條例上述要求）。（5）在檢查電動機軸向與水泵的轉向相一致后，裝上聯(lián)軸器的聯(lián)接柱銷。4、進出水管路應另設支架支撐，不得借泵體支承。5、水泵與管路之間結合面，應保證良好的氣密性，尤其是進水管路，必須保證嚴格的不漏氣，并且在裝置上應無窩存空氣的可能。6、如水泵安裝在進水位以上時，為了灌泵起動，一般可裝底閥，也可采

18、用真空引水的方法。7、水泵與出水管路之間，一般需裝閘閥和止回閥（揚程小于20米的可不用），止回閥裝在閘閥后面。8、泵、電機安裝尺寸以常用電機計算，根據(jù)用戶需要或實際選用的其它電機，其安裝尺寸請用戶按實際計算。以上所述的安裝方法是指不配帶公共底座的水泵機組。安裝配還公共底座的泵，用調整底座與混凝土基礎之間的楔形墊鐵來校正機組的水平，然后在其間灌注混凝土。其安裝原則與要求，和不配帶公共底座的水泵相同。 五 使 用 說 明1、起動與停止：（1）起動前，轉動泵的轉子，應該輕滑均勻。（2）關閉出水閘閥，向泵內注水（如無底閥則用真空泵抽吸引水），要保證泵內充滿水，無空氣窩存。（3）如果泵上裝有真空表和壓力

19、表，要關閉其與泵相連接的旋塞再起動電動機，待轉速正常后現(xiàn)打開；然后逐漸打開出水閘閥，如流量過大，可以適當?shù)仃P小閘閥進行調節(jié)；反之流量過小時，將閘閥開大。（4）均勻地擰緊填料壓蓋上的壓緊螺母，使液體成滴狀漏出，同時注意填料腔處的溫升。（5）當停止水泵運轉時，要先關閉真空表及壓力表旋塞和出水管路上的閘閥，然后關閉電動機的電源，如所處環(huán)境的溫度較低時，則應將泵體下部的四方螺塞打開，去掉剩水，以免凍裂。（6）長期停止不用時。應拆開水泵，將零件上的水擦干，在加工表面涂上防銹油保管好。2、運轉：（1）水泵軸承最高溫度不應超過75（2）潤滑軸承用的鈣基黃油的數(shù)量以占軸承體空間的1/31/2為宜。（3）填料磨

20、損時可適當壓緊填料壓蓋，若磨損過多應加以更換。（4）定期檢查彈性聯(lián)軸器部件，注意電機軸承溫升。（5）運轉過程中，如發(fā)現(xiàn)噪聲或其他不正常的聲音時，應立即停車，檢查其原因，加以消除。（6）不得任意提高水泵的轉速，但可以降低轉速使用，如本型泵額定轉速為n，流量為Q，揚程為H，軸功率為N，降低轉速不n1,降低后流量、揚程、軸功率分別為Q1，H1和N1，其相互關系，可用下列公式進行換算： Q1=( )Q H1=( )2H N=( )3故 障原 因排除方法一、泵不吸水，壓力表及真空表的指針劇烈跳動1.注入的水不夠；2.管路或儀表漏氯。1.再往泵內注水；2.擰緊堵塞漏氣處。二、泵不吸水，真空表顯示高度真空。
