["屏蔽泵"

Reply #42018-10-16

,"屏蔽泵启动以后出口压力表显示1.5兆帕，额定电流是80，启动后电流从88一直下降，下降到15后维持到2秒就跳车了，个个给分析一下是什么原因"

Reply #52018-10-16

,"电流下降说明流量的降低，流量的降低可能会导致轴承的润滑不良屏蔽泵一般输送轻烃类组分过滤器堵或者介质内气相多轴承温度升高跳闸"

,""本帖最后由 383596_FFPZ 于 228Z-ZZ16 15:54 编辑输送是什么介质Z是易汽化介质吗Z如果是的话Z就是泵处于临界汽蚀状态运行并且汽蚀逐渐加重扬程下降轴功率不断降低最后造成负载跳闸保护Z请核实装置汽蚀余量和泵汽蚀余量是否合适Z再看看泵内冷却循环回路是否有堵塞屏蔽套发热热量没有及时被带走Z如果都不是那么就是泵选型有问题"

,""我Z觉得介质汽化的可能性大一点"

Z"是什么保护引起的跳车"

Reply #92018-10-25

Z"后来电气说是电流欠载保护"

Reply #102018-10-25

Z"首先泵跳停的原因是什么从你的描述来看不存在电流过流保护跳停我认为是缺液轴承抱死可能性大"
