突然出现的,从开始22A升到27A就关掉了;将泵大修之后仍然是这个样!

介质是柴油,不受;出口阀开度不变。

运转温升造成的?难道是轴承游隙过小,振动噪音怎样
Reply #72018-12-15
完全符合技术标准大修后仍然没有改变!是不是电机问题?
Reply #82018-12-15
变大是正常的,电机线圈导线的电阻随温度升高而变大,即电机的发热功率变大,如果电机的输出功率不变,则电机的输入功率要变大,当电压不变时,电流也会变大。

电机应是355kw,水泵型号应是300-500,或400-500,如叶轮松,振动会加聚,估计是背靠背轴承缝隙过小,开机后温升,轴承过紧,电流会上升。

建议不要停泵,继续开,看看最终电流升到什么程度,把问题彻底暴露出来,一般情况下流量、温度、介质密度都会造成电流变化,这些原因都正常,就只能是电机原因了。

测量轴和轴承温度了没?停下后盘车与之前有区别吗??

振动,声音如何,查查对中

只要电流稳住了,剩下的工作就是继续运行,可能是工艺上流量和工艺操作有了变化造成的。
