["Sur le problème de de la quantité de la pompe de fluide chaud"

2019-11-20View Original

Thread Content

"Chers experts,, mon pompe de de de fluide chaud à la base de est remplie de carbur烧油温度大概在30度左右,3月份的时候量大概在245t/h,期间切换到备用泵运行半年,然后从1月份切回该泵运行,泵出口出口量在235t/h,量大概低了11t/h,出口压低了1公斤,但机泵运行稳定无异常振动、杂音,该泵中间也未进行检修处理,入口滤网干净,请教各位专家该泵的流量和压力下降可能由于什么原因引起的呢?是否与气温有关?泵体未包保温,3月份气温大概也度左右,从ide月份气温大概也度左右,谢谢指教"

"Est-ce que le courant a changé?如果电流没有什么变化,可能是口环间隙变大。"

"Les conditions de fonction作有没有变化?塔的液位是不是比之前低了?液位低相当于进口压力降了"

"Les valves de retour ou des出口备用泵的出口阀没有关死。或者备用泵单向阀内漏"

"Le courant est de de加上之前,由原来的88变为了99"

Les conditions n'ont变化,而且备用泵的量和和这台泵之前的量基本差不多"切换到这台泵后,量就下降了"

"La valve de sortie de出口出口备用泵的出口阀应该是严的"因为我切换泵时 "备用泵未停,只是关闭出口出口阀 "备用泵的压力高于这台泵 "应该不存在从这台泵到备用泵"

"YIl a-t-il une ligne de retour? "电流大了 "可能性是泵内循环大有旁通回流 "看看下"

"D'ab检查塔物料的密度、粘度等等和以及塔的液位是否有变化"如果排除这些因素的变化之后 "再再检查回流阀是否未关死或者有内漏"最后才检查泵设备本身的问题"

"Cette comportement est vraiment é异怪异"电流变大 "说明泵的输出增加 "也就是泵的流量变大 "扬程变小小只有一种可能泵的性能降低了了"可以微信或手机号:131624857"

"Peut-停泵前 "没有没有缓慢冷却 "泵的轴承处有积碳现象 "导致再次启动 "负载增大 "泵和电机为直连 "导致电机丢转数 "继而流量、压力都下降 "电流增大"
