继续翻译剩余的文本。

铭牌什么参数，流量扬程

泵的能力与现场实际需求不符，需查订货数据

泵出口管路是否是空管，建议慢慢使泵后管路充满水后再开大出口阀门。

新安装，试运行后，两年没用了

Reply #72020-06-04

既然2年了，解体检查，更换零件。

扬程48出口才0.2，确认转向正确吗

Reply #92020-06-08

意思是之前试运行的时候是OK的，那就检查下出口的流量，看是不是里面堵了，再不行把泵拆下来叫南方的人来看看不就知道了

出口流量检查过，没问题

Reply #112020-06-16

阀门全关看憋压是否能达到泵额定扬程的1.2-1.4倍。再一个听泵体内是否有刮蹭的声音、轴承的声音正常不。

你的使用流量超过泵的额定流量，导致过电流（一般离心泵使用时超电流原因）。关闭泵出口阀，你查看下出口阀前的压力有没有小于要求值，如果没有，您可以通过关闭流量终端的阀来减小流量，可以提高系统压力。

应该是水泵跑到大流量点运行了，可以调节下出口阀门，把出口压力憋到0.48MPA看看运行情况
