"离心泵进口压力分析"

离心泵运行运行罐体内压力 \ud83d\ude00 \ud83d\ude1罐内有4米水柱，那进口压力不计压降损失，就是 \ud83d\ude4兆帕吗？ \ud83d\ude3d\ude1我认为进口静压是 \ud83d\uds4兆帕 "泵在运行过程中进口流速快进口压力肯定不会是 \ud83d\uds4比这小多了 "是这样吗 \ud83d\ud1a"

"3. 不不一定 "还要看泵的入口管段及管管附件的阻力~~"

"4. "静压是这样 "泵启动后由于管管损失 "就不是这个数了"

"5. "泵启动后，进口压力会降负压吗"

Reply #112018-07-04

"6. "泵启动后会进口会变为负压吗"

"7. "取决 \物料蒸汽压与进口管管阻力 "量很大 "蒸汽压很低（小于 \ud83d\ud4MPa "的是是有可能为负压的"
