"두 대의 액화 화학 물질을 운반하는 centrifugal 泵并联送料，杨程446米，流量为9995立方米每小时，一台泵有8s％的回流另一台无回流有其中一台突然没流量泵有震动有什么原因？"

" �泵汽蚀了有进口过滤器堵了"

"过滤器清洗了没发现有异物三台泵两用一备有来回切换运行两年时间就发生两次这样情况"

"是不是天气热温度高造成气蚀了。查一下汽蚀余量情况。"

"是不是没有流量还是有一部分量？可能是气蚀也可能是进出口阀门故障也可能是进口异物还有可能是叶轮脱落或者叶轮键连接处故障。"

审定不清楚去除了叶轮脱落可能项:P"

"在突然没流量的时候入口压力有什么变化？"

"个人判断是那台打回流的泵！想个极端情况如果是全回流状态下介质会被逐渐加热引起气蚀现象出现！"

泵入口压力不变两台泵并联送料另一台没问题"

"看看看看泵的冷却水正不正常！"

"可能是气蚀。关闭泵出口出口阀门憋压试试试验。"

"现象上看是气蚀了检查一下入口过滤器另外看看入口管道是不是有轻微泄露点"

有结果了吗建议建议结合电机电流观察"

"是不是测流量的东西不准了"

Reply #162018-08-08

"你是咋判断没量的有视镜、视流镜、流量计吗？还是仅仅通过压力判断的？"

"泵回流有没有冷却器8s％回流量很大的热量很高可能导致入口液化烃温度达到饱和蒸汽压导致泵气蚀。回流流程是回到泵入口吗有详细流程更好分析。"
