[". Le ta量也和扬程有关系的,出口背压低,流量容易大于额定流量同时电流不超。。屏蔽泵的电机都是定制的,,是按照设计数据来的,不会按照清水来做电机的

[". � pérdida电最好有厂家提供的性能曲线,可以方便查看问题。

"5. " �流量超了而电机电流不超,肯定是扬程降下来了,如果能满足 你需要求没有问题毕竟流量大工作效率要高。

"6. " �谢谢了!厂家说铭牌参数是根据清水标定的。

"7. 一个多年前的泵了,我再找一下看看有没有性能曲线吧!谢谢您了!

"8. �能满足现场需要,就怕对屏蔽泵有什么不良影响。谢谢您了!

"9 一个认为长期在楼主介绍的工况下运行,电流不超额定电流、泵又没有超振动、温度、异响等异常现象可以运行、不会对泵造成不良影响。

"9 除非是采购时你们专门要求否则厂家大多会按水联运的清水介质匹配电机的因此屏蔽电机匹配的大。 长时间不在额定工作点使用会导致轴向力力不可控(除非你们采购时1550立方是考核工作点) �轴向力大导致轴承端面使用寿命缩短并且要密切关注如果转子轴向位大会导致叶轮等机械部件磨损损失会很大!
