既然知道了温度问题,就得想办法降温冷却吧。加设个冷却器试试。

这种泵关键在于选材,经常抽空,必须有可靠的机封冷却装置。既然可靠性差,就选用离心泵,做一开两备,也花不了几个钱。

泵进口的容器换为压力容器,加压。或者液位控制高点。或者冷却器降温。
Reply #52018-04-14
泵进口为池子,无法加压。液位控制怎么高?怎么降温啊

如果原先的泵电机是两极的,可以考虑选个四极(转速低的)泵。 如果已经是四极的了,可以考虑加诱导轮。 如果诱导轮不可行,可以挖个坑,把泵沉下去,以提高液位高度。 或者采用液下泵或其他形式的泵

您的意思是换电机,为什么说低转速的,可以呢?
Reply #82018-04-14
楼上说的很全面,这种情形下选抗汽蚀材料,结合装置汽蚀,2级泵不能达到就可以先加诱导轮,不行了再选4级,一般4级就肯定可以选出来,就是贵点。以前的单位2级加诱导轮没做成功,赔了个4级泵,亏了十几万:lol

你之前也没说是池子啊,条件不提前说清楚怎么分析?
Reply #102018-04-16
是循环水池吗? 凉水塔降温可行吗?
Reply #112018-04-16
入口和出口阀门之前加回流线,让出口介质回流到入口,可以起到加压,补充在抽空时所需的介质,回流阀门不用开太大,控制到不影响出口流量和压力就可以
Reply #122018-04-16
循环水池水温度不会那么高
Reply #132018-04-16
想改变转速的话可以让电气车间加变频器
Reply #142018-04-16
前工段来的废液,放在池子里,然后,用泵抽走。现在温度高,想办法,把温度降下来
Reply #152018-04-16
1.前置诱导轮。2.降低吸入口高度。将为负高度。3.采用抗气蚀材料。
Reply #162018-04-17
同意加诱导轮,但是前置诱导轮需要联系厂家,转子需要拆出去做动平衡,费事费力不能在短时间内解决问题,您说呢
