What measures should be taken to prevent siphoning in the centrifugal pump when pumping liquid from the third floor to the first floor?
The problem you need to solve is definitely not the same as the question you raised. If you don’t understand the technology, you should send the original information about the problem without adding your own interpretations, as that can lead to misunderstandings
From the third floor to the first floor, why is a pump still needed?
Personally, I think installing a flow meter should solve the problem; there’s an issue with the process design
Why is there also a siphon effect in the centrifugal pump?
I don’t get it. There’s a height difference from the 3rd floor to the 1st floor; why is a pump needed to move water? If measurement is to be achieved, a weighing module can be installed on the tank on the 3rd floor, or a flow meter can be added to the pipeline
2# You’re right; the original poster didn’t provide other necessary conditions for considering this issue, which led everyone down the wrong path. :Lol, I wonder: if the operating pressure of the receiving equipment on the first floor is much higher than that of the material extraction equipment on the third floor (by several bars, for example), would there still be such a thing as a siphon effect? It is only necessary to take into account the effect of the head difference when determining the suction pressure and head of the pump.
To go from the third floor to the first floor, one can simply use the difference in material levels. At most, a flow meter and a control valve can be installed in between to solve the problem; pumps are only necessary if pressure elevation is required.
I don’t understand what you mean; how can siphoning occur with something that is pumped using a metering pump?
