1、运用SAP型单级双吸中开泵的基本常以运用SAP型单级双吸中开泵的基本常识SAP型单级双吸中开泵的概述：SAP型系单级、双吸水平中开式离心泵，适应于工厂、城市、矿山、电站、农田、水利工程等领域。用于输送不含固体颗粒的清水或物理、化学性质类似于水的其它液体，被输送的介质温度为0C80C,允许最大进口压力0.6MPaSAP型单级双吸中开泵的结构型式：泵为卧式安装，泵壳于轴心线水平分开，上部为泵差，下部为泵体，吸入口和吐出口均在泵轴线下方的泵体上，其中心线与轴线垂直，检修时不需拆卸进水和出水管路，即可揭开泵釜，取出转子部件。除18SAP-30型泵为滑动轴承，其它型号泵轴承均采纳滚动轴承，轴承端盖密封采

3、联轴器外圆偏移允差0.1亳米，两联轴湍端面间隙一周上最大和最小的间隙差别不得超过0.3亳米。3、 泵的吸入管路和压出管路应设有支撑，不允许管路的雨量干脆由泵来承受，检查管路，仪表等接口处密封是否良好。泵可能发生的故障、缘由及解除方法：1、水泵不吸水：压力表及真空表的指针猛烈跳动缘由及解决方法：注入水泵的水不够：水泵或仪表漏气再往水泵内注水；拧紧或堵塞漏气处2、水泵不吸水，真空表显示高度真空缘由及解决方法：进水管路没有打开或已堵塞；吸水阻力太大：吸水高度太大而超过允许值。检查进水管路：清洗或更换吸水管：降低吸水高度3、看压力表水泵出水处有压力，而水泵仍不出水缘由及解决方法：出水管阻力太大：旋转方

4、向不对：叶轮淤塞：水泵转速不够o检雀或缩短出水管：变更电机转向；清洗叶轮：增加水泵轴的转速4、流量低于预料绿由及解决方法:水泵淤塞；密封环磨损过多：转速不够。清洗水泵及管道；更换密封环；增加水泵轴的转速5、水泵消耗的功率过大缘由及解决方法：填料压盖过紧；叶轮磨损：水泵供水量增加。拧松填料压盖或将填料取出打方；更换叶轮；调整闸阀降低流量6、水泵在工作过程中出现异样声音，流量下降宜到不出水：平衡装置早期磨损缘由及解决方法：闸阀开得太大：吸水管阻力太大：在吸水处有空气渗入；吸水高度过大：所输送液体温度过高调整闸阀以降低流量；检查吸水管道；检查底阀；削减吸水高度；拧紧或堵塞漏水处：降低液体温度7、水泵

5、振动缘由及解决方法：泵轴与电机轴线不在同一条中心线上把水泵和电机的轴中心线对准8轴承过热缘由及解决方法：没有油或油脏：水泵轴与电机轴不在一条中心线上/注油或换油：把轴中心线对准SAP型单级双吸中开泵的性能：参数型号流量Q3/h1./s扬程H转速n轴功率Pa配带电动机效率功率型号kw必需汽蚀余量叶轮名义直径进出口彳仝泵重mmr/minkw%mmmmmkg6SAP612618021635.050.060.0104978729804959.564.875Y280S-27380793.03.85.32701501001606SAP-611917020433.147.3. 74.725615010016
