Problem of high noise in the bypass pipeline
Thread Content
I have a question for the experts: The unit is equipped with a primary bypass pipe. Since it isn’t used very often, the pipe design is relatively thin; as a result, the gas flow velocity reaches 40 m/s, which causes significant noise. I wonder if any of you experts have encountered such a problem; do you have any experience or lessons to share? The only thing that comes to mind is 1: increase the pipe diameter to reduce the flow velocity ； 2. Increase pressure, reduce flow rate ； Can perforated plates reduce noise? I remember a orifice plate was added to the vent line. Thank you to all the experts.
Whoever answers, the original poster will say: Using one’s age as an excuse! Then come some vulgar insults – who would dare to answer? Just take a look. For some people, being ignorant is considered a skill.
If you want to reply, go ahead; if not, then don’t. There’s no need to start giving orders right away
Oops, it’s been banned. Good deeds bring good rewards, and those who observe things from the side can see clearly that what you thought was a lesson was actually a kind reminder. If you’re not humble and insist that you understand everything correctly, you’ll end up slapping yourself in the face. Study hard from now on*; if you don’t understand something, read books by yourself – otherwise your progress will really come to a standstill. The more water there is in the bottle, the less it will shake. Saying that there are specialized fields for different skills is something only humble people would say. As for you saying that, it’s actually just an excuse for your own ignorance.
I’m helping you overcome your tendency to rely on your age; instead of thanking me, you come up with more excuses.
Has Haichuan really declined? That’s what I see after reading the request for help. The realms of learning*: not knowing that one does not know, knowing that one does not know, knowing that one knows, not knowing that one knows. If we don’t pursue knowledge*, what are we here at Haichuan for?
