请教各位大侠,水喷射泵的尾管是否可以倾斜(比如45度)向下连接到储液罐?一定要垂直连接吗?尾管是否要插入液位以下?如果用来吸气体(比如除去尾气或者除尘),进气的速度有要求吗? 如果是对非密闭系统抽气,抽气量会受影响吗?谢谢!

斜45度不好看吧。横平竖直安装会更美观。别外插入液面下会增加阻力,不利于抽空。

你这是抽真空用的么,那么什么角度都行,只要你安装方便,不能插到水里,阻力太大

如果真是有必要,倾斜是可以的,对抽真空影响不会太大。但实际上从安装外观,淋水的收集、环境都会不利。不主张你这样安装。喷淋管不能插入液位以下,会直接导致真空度下降。

现在确实有必要倾斜,但是还担心倾斜对排水的影响(担心出口压力不够),倾斜没有垂直效果好 。但是否可以通过增加喷射泵和水槽倾斜管道的垂直距离比直接垂直管道高来弥补, 比如距离至少大于11m?谢谢!

这样做没有用的,只要喷射泵选择合适,水压足够,垂直管倾斜对真空度影响有限。

不可以,阻力大。必须垂直。不必须插入液面下。根据进气量及所达到的真空度来选择喷射泵。
