Who has ever encountered a situation where waste cannot be discharged using a vacuum package?

Who has ever encountered a situation where waste cannot be discharged using a vacuum package? There is a waste tank connected to the bottom of my vacuum bag; when there is material at the bottom of the bag, it cannot be discharged. What’s going on?

The reason it can’t be discharged is due to the negative pressure in the vacuum pack; release the vacuum pressure and the waste can be removed.

There are two possibilities: either the pipe is blocked. Hehe, it depends on the type of medium used. But I guess that’s not the reason in your case; Another issue is insufficient pressure; you can install a pressure balance line on top of the drain tank and the main tank. ——Hehe, it’s likely that you can’t just make holes in your vacuum tank! Finally, the simplest and most effective method in practice is to pick up the F gun and give the drain valve a few taps – that’s basically it. Be careful with the force though; I won’t compensate if you break it, haha

The reason it can’t be discharged is due to the negative pressure in the vacuum pack; release the vacuum pressure and the waste can be removed. You can try this method: if the vacuum tank can be isolated, then the inlet valve can be closed and the bottom valve opened to allow discharge. If there is no discharge even when the tank is at atmospheric pressure, there are mainly two solutions: first, use steam for heating; second, replace the bottom valve with a ball valve and use something to push air upward. Make sure the part that you hold is bent to prevent splashes from reaching your hands and body!

I’ve encountered this issue while driving; usually, one just uses a wrench to tap on it a few times, but that’s not a lasting solution. A special vacuum-breaking device was designed to address this problem
