DT型脫硫泵
一、DT型脫硫泵的安裝
1安裝前的檢查
?。?）DT型脫硫泵安裝前應首先按《裝箱單》檢查設備的型號、參數(shù)是否正確，零部件、隨機攜帶的技術資料及質量證明資料是否齊全。
?。?）?詳細閱讀此使用說明書，DT型脫硫泵掌握有關的技術要求和操作要領后，方可進行安裝。
2泵的安裝找正
?。?）泵機組安裝后，機組的中心線應與地基中心線一致；機組的中心高與設計值的偏差應不大于±2mm，機組的水平允差為0.1/1000?。
（2）對于采用膜片聯(lián)軸器傳動的泵機組，找正方法如下:找正是安裝中最重要的環(huán)節(jié)，安裝DT型脫硫泵一般來說主、從動端設備初始對中越好，那么傳動系統(tǒng)的運行就越平穩(wěn)，為保證最佳對中精度
二、DT型脫硫泵反沖洗系統(tǒng)
顧客現(xiàn)場應設置大型脫硫循環(huán)泵用反沖洗系統(tǒng)。反沖洗系統(tǒng)是指從泵出口注入清水，流經(jīng)泵腔和葉輪后從泵入口排出的沖洗系統(tǒng)。如果泵停機，應在停機后進行反沖洗,一般不少于5分鐘,使機械密封的腔體中和密封副周圍沒有殘留介質。如果泵由于其它原因要被停用保存，機械密封應拆出泵外，用中性清潔劑清理后涼干，然后裝回清理過的泵體，再作儲存。對停機時間較長的泵,投入運行前，應先進行反沖洗再運行。同時應確保進出口閥門關閉可靠，避免出現(xiàn)漿液漏入泵腔的現(xiàn)象。
三、DT型脫硫泵的調整
泵在安裝找正后應進行檢查與調整。
1、DT型脫硫泵泵的前間隙調整
為保證泵的高效運行，使用一個時期后，在運行條件不變的情況下，DT型脫硫泵的流量及效率下降，電流有較大變化時，必須定期對脫硫循環(huán)泵的前間隙進行調整，具體調整步驟如下：
（1）裝單端面機械密封的泵，將機械密封集裝板5旋入集裝槽并固定，DT型脫硫泵松開機械密封軸套與泵軸套鎖緊螺栓4（兩個法蘭盤連接螺栓）。
?。?）松開壓緊螺栓3。
?。?）松開調整螺栓上的電機側螺母2。
（4）均勻擰緊調整螺栓上的中間壓緊螺母1，使轉子向泵頭方向移動，邊擰緊邊盤車，直到盤不動為止。注意盤車的方向應按泵的工作轉向。
?。?）用深度尺測量后軸承壓蓋端面與懸架端面的間隙L=a；此時，葉輪與入口短管的法向間隙δ＝0。
?。?）松開調整螺栓上的中間壓緊螺母1。
（7）均勻擰緊調整螺栓上的電機側螺母2，使轉子向電機方向移動，DT型脫硫泵用深度尺檢查間隙L，直到L＝ａ＋b為止(b值見表2，此時法向間隙δ=0.9～１mm),注意間隙應均勻一致。
?。?）擰緊調整螺栓上的中間壓緊螺母1、懸架蓋壓緊螺栓3，使轉子的軸向位置完全固定。
?。?）擰緊機械密封兩軸套鎖緊螺栓4，集裝板5旋出集裝槽固定。
