水泵电机温度高,但电流不大,是什么情况?
Reply #42019-07-11
管道离心泵33KW四级电机,额定电流58A,工作时电流只有38~40A左右,三相电流也都基本一样。但是电机温度很高,工作2小时后能达到75度左右,然后就没敢继续运行,怕电机高温损坏。 请问请问请问水泵电机温度高运行电流不大,会是什么问题?另外,同样功率,二级电机和四级电机哪个发热量大?

电流不大但是温度高,应该是电机自身问题,从电和机械两个方面进行排查:测量检查下绕组,检查下润滑脂和轴承状况,风扇是否风冷正常,电机振动噪音有无异常,

是电机质量问题吗?我们分析如果机械方面有问题,或者电机轴承等问题,会造成负载大导致电流高,但电流却很低,工作时却额定电流很小。
