El tubería de la出口管道道长问题
Reply #22019-08-12
2 barcelona出口管路过长,末端为喷嘴,喷入常压罐,导致初次启动时,工艺介质需要一定时间挤出空气并流至末端喷嘴,但是泵建立起扬程时间较长,达到十几秒,此段时间泵机封容易烧,管道的总阻力是考虑在泵扬程里面的,但是不是因为管道过于长,造成泵建立扬程的时间较长,烧机封是不是这个原因,请高手分析下,谢谢。

烧机封的原因除了水有杂质外,还有一个比较重要的原因,供水不足,导致烧机封。

泵的运行工况点是否与设计的接近,到喷嘴这段时间内正常泵内一直有液体的。机械密封坏应该是其他原因

离心泵启动过程,你们是怎么操作的?出口阀门全开了?

此泵如果是靠泵出口介质作为密封冲洗介质的话,建立扬程前泵出口阀开度过大会导致泵出口压力低可能使机泵密封冲洗无介质机封损坏。启泵缓慢开大出口阀确保泵出口压力在正常值。
