八、SPG型管道式屏蔽泵-安装说明

   1、安装前应检查机组紧固件有无松动现象，泵体流产内有无异物堵塞，以免水泵运行时损坏叶轮和泵体。

   2 、安装时管路重量不应加在水泵上，应有各自的支承体，以免泵变形影响运行性能和使用寿命。

   3 、为了不使杂质进入泵内而堵塞流道影响性能，应在泵进口前面安装比吸入管截面积大3~4倍的过滤器。

   4 、如泵用于输送热水液体时，为了不使泵承受管路的热变形，泵可以不固定底脚螺栓，当管路系统在热胀冷缩时，使泵与管路同时移动。

   5 、为了维修方便和使用安全，在泵的进出口管路应各装上一只调节阀门及在泵进出口附近各安装一只压力表，以保证在额定范围内运行，确保泵的正常运行和使用寿命。

九、SPG型管道式屏蔽泵-维护与保养

      起动前的准备及检查：

   1、 检查屏蔽电机和起动设备的接地装置是否良好和完整，接线是否正确，接触是否可靠。

   2、 对新安装和*停用的屏蔽电机，使用前应检查电机定子绕组对地的绝缘电阻。

   3、管路中必须充满输送液体，否则将影响电机的使用寿命。

      运行中的维护保养

   1、 定时记录电源电压的变化和电压的不平衡度。电源电压过高或过低，三相电压的不平衡造成电流的不平衡，都可能引起电机的过热或其它不正常现象。

   2、定时记录电泵的负载电流和不平衡度。电泵发生故障时大多数会反映到定子绕组的电流的剧增，使电机过热。

   3、定时记录管路中的输液温度，以确保实际的输液温度低于或等于铭牌上所规定的输液温度，避免电泵*处于超温状态下运行，而降低电机的使用寿命。

   4、 定时记录电泵进、出口端上的压力表数值，进口处压力表的数值不得小于零，出口处的压力表数与进口处压力表数的差值，必须符合铭牌上的规定的压力值。

   5、电泵在每一次使用前要排气一次，在*运行时，必须每星期排一次气。因泵经长时间运行，水分子在电泵内被高速搅拌和撞击，同时被输送的介质带有一定的温度故液体浆产生

   6、注意电泵的气味，振动和噪声，电机的绕组因温度过高就会发出绝缘的焦味。一般的机械故障会反映为振动和噪声。因此发现异常因立即停电检查。

   7、定时检查电泵循环液通路，过滤装置是否有阻塞现象。

   8、定期维修测量石墨轴承和轴套之间的间隙，以确保定子屏蔽套与转子屏蔽套之间间隙均匀，运转可靠。一般情况以下表为限，如超过表中的规定就应修复或更换。轴套外径（mm）磨损极限间隙（mm）标准zui大间隙（mm）>18~300.400.131>30~500.450.158>50~800.500.192 9、定期检查叶轮口环与泵体的配合间隙，因此间隙会直接影响电泵的

十、SPG型管道式屏蔽泵-起动、运转和停车

     起动、动转：

   1、灌水排气、打开进口阀，使液体充分进入泵腔内，打开电机顶部排气阀，待满后关闭排气阀。

   2、关闭出口阀，以减小起动电流。

   3、检查各部位是否正常。

   4、接通电源，起点动确定正确运行方向。

   5、逐步调节出口阀的开度，尽量使泵在额定性能范围内工作。

   6、泵的运转过程中，如发现有异常，应立即停车检查排除。

   7、检查电机电流值及温升是否符合要求。

      停车

   1、关闭吐出管路阀门。

   2、切断电源，停止电机运行。

   3、关闭进口阀。

   4、泵如*停用，应放尽泵内的液体。
