1 安装前的检查
（1） DT型脱硫泵安装前应首先按《装箱单》检查设备的型号、参数是否正确，零部件、随机携带的技术资料及质量证明资料是否齐全。
（2） 详细阅读此使用说明书，DT型脱硫泵掌握有关的技术要求和操作要领后，方可进行安装。
2 泵的安装找正
（1） 泵机组安装后，机组的中心线应与地基中心线一致；机组的中心高与设计值的偏差应不大于±2mm，机组的水平允差为0.1/1000 。
（2） 对于采用膜片联轴器传动的泵机组，找正方法如下:找正是安装中最重要的环节，安装DT型脱硫泵一般来说主、从动端设备初始对中越好，那么传动系统的运行就越平稳，为保证最佳对中精度
二、DT型脱硫泵反冲洗系统
顾客现场应设置大型脱硫循环泵用反冲洗系统。反冲洗系统是指从泵出口注入清水，流经泵腔和叶轮后从泵入口排出的冲洗系统。如果泵停机，应在停机后进行反冲洗,一般不少于5分钟,使机械密封的腔体中和密封副周围没有残留介质。如果泵由于其它原因要被停用保存，机械密封应拆出泵外，用中性清洁剂清理后凉干，然后装回清理过的泵体，再作储存。对停机时间较长的泵,投入运行前，应先进行反冲洗再运行。同时应确保进出口阀门关闭可靠，避免出现浆液漏入泵腔的现象。
三、DT型脱硫泵的调整
泵在安装找正后应进行检查与调整。
1、 DT型脱硫泵泵的前间隙调整
为保证泵的高效运行，使用一个时期后，在运行条件不变的情况下，DT型脱硫泵的流量及效率下降，电流有较大变化时，必须定期对脱硫循环泵的前间隙进行调整，具体调整步骤如下：
（1） 装单端面机械密封的泵，将机械密封集装板5旋入集装槽并固定，DT型脱硫泵松开机械密封轴套与泵轴套锁紧螺栓4（两个法兰盘连接螺栓）。
（2） 松开压紧螺栓3。
（3） 松开调整螺栓上的电机侧螺母2。
（4） 均匀拧紧调整螺栓上的中间压紧螺母1，使转子向泵头方向移动，边拧紧边盘车，直到盘不动为止。注意盘车的方向应按泵的工作转向。
（5） 用深度尺测量后轴承压盖端面与悬架端面的间隙L=a；此时，叶轮与入口短管的法向间隙δ＝0。
（6） 松开调整螺栓上的中间压紧螺母1。
（7） 均匀拧紧调整螺栓上的电机侧螺母2，使转子向电机方向移动，DT型脱硫泵用深度尺检查间隙L，直到L＝ａ＋b为止(b值见表2，此时法向间隙δ=0.9～１mm),注意间隙应均匀一致。
（8） 拧紧调整螺栓上的中间压紧螺母1、悬架盖压紧螺栓3，使转子的轴向位置完全固定。
（9） 拧紧机械密封两轴套锁紧螺栓4，集装板5旋出集装槽固定。
