["泵의 높이는 어떻게 선택하나요？

Reply #32019-12-20

s.슬러그 펌프, 흐름량 23m?h/시 높이 6미터, 길이 155미터, 파이프 직경 DN655, 75개의 구부러짐이 필요하며, 필요한 높이는 얼마나 되나요？ 이렇게 선택하면 흐름량이 얼마나 손실되는지 확인할 수 있을까요？

지금 사용하는 놓이는 적합하지 않으며, 흐름량 표가 없습니다. 대략적으로는 매 시간 약 13m?

这是因为泵系列里面没有合适的规格，你的工况流量和扬程都不是很大，关键在于管道的阻力损失，最好的办法是该换大功率的电动机，否则只能选高扬程的泵，最好把你的介质密度，粘度发过来，然后我计算一下，或许能对你有帮助，加我微信也行yfl20179，这样我发文件给你比较方便，不收费的！

谢谢了粘度没测过我们没有那个仪器

你这么远的距离，压头损失巨大。具体损失还得看管道材质、粘度等参数！

计算H=73.5M，可以选H=80M

算吧，局部+沿程损失，条件不够需要补

Reply #102019-12-29

介质的密度，这个必须给出

Reply #112020-01-03

用DN65的管道扬程最少要100米，

化工原理上写的很详细了，算管道中的流体阻力当量长度和当量系数法在加上你需要的静压头就大概估出来扬程了。泵还有很重要的计算就是算算汽蚀余量
