["[1多个真空容器每隔s-分钟开启一个，如何控制真空容器的真空度先后达到一致

Reply #32020-08-21

,个大佬们，我有5个约a.6立方米的真空容器共用一套真空系统每b-分钟开启一个真空容器阀门怎么能控制后开启真空容器时不影响前面真空容器的真空度我想根据开启真空阀门的顺序依次达到真空度但是第二个真空腔开启阀门的时候第一个真空腔以及抽到一定的限度了肯定需要中和前面的真空度才能一起继续提升有没有什么办法控制

泵流量足够大主管足够粗支管细一些或者阀门开小一些可以维持主管道压力低于容器压力就不会串气了

建议每个罐真空抽出管加单向阀

单向阀有阻力真空度下不去

我直接加个缓冲罐先把缓冲罐抽到一定真空度再开启阀门这样应该可以但是又有新问题会不会出现瞬间压力降低出现抽气的噪音很大出现爆鸣
