介绍‘经济流速’

管子的流速是任意设定的吗？不是。从流体力学可知当管内介质流速越大则阻力越大。当流速越小时，虽然流动阻力小了，对于同样的流量所需要的管径却大了，造成设备成本的升高。于是人们考虑到这两条因素取了一个合理的流速称为经济流速，人们根据流量选择管径就是依靠经济流速计算得出的。`

有没有关于输油管路的流速啊？

zhou451201000 发表于 2005-10-29 19:46

在工程上对各种介质（液体，气体，两相流，液压油路等）都有了各自管道中的经济流速和相应的计算公式。
+k9dnJ^ P?U7^u 看到你的贴子后，我查了下我手头资料，由于资料有限未见输油管路流速的计算。你可以找下资料，我也想法找下资料，找到后我想法通知你。

eh}.g7{-PIF 谢谢哈！现在的泵大多数向石油、化工发展。油特殊性决定了他的流速。上次有人问我这么快的流速会不会引起摩擦火花导致爆炸呢。_gtt T.oP l
把我给问住了。

特殊

有没有超低温介质液氧的相关数据？

hn3237161 发表于 2006-9-21 01:29

85198277 你需要液氧泵的什么数据，我现在设计的卧式离心液氧泵在国内是最大的，流量60立方／小时，扬程108米，已经用在我国的航天发射场了，不知道对你有没有帮助。我的[email]fuyiping15@yahoo.com.cn[/email]
