Roots blower!
Thread Content
Not long after the fan was turned on, the pressure changed from negative to positive! The fan is fine too! The pipes are fine too! Does anyone know what’s going on?
The fan’s rotation direction is reversed, or the inlet and outlet are connected in the wrong order
Pipe disconnected! It starts up normally! The rotation direction is fine
Is it the inlet changing from negative pressure to positive pressure? It is likely that the installation clearance of the rotors (between the rotors and between the rotors and the casing) is excessive, resulting in insufficient conveying capacity.
You mean that the efficiency of the Roots blower has decreased, so it isn’t able to draw in the required amount of medium per hour, which causes the medium to accumulate at the inlet.
It’s air that’s being drawn in; it’s everywhere. There’s no such thing as a situation where it can’t get in through the inlet
How is this positive or negative pressure determined? Is there any air leakage at the connections of the inlet and outlet ducts?
Disconnect the pipe! When turned on, the inlet is under negative pressure! The outlet is under positive pressure; there’s clearly wind!
Haha! Don’t be arbitrary! A lighter molecule can also cause similar situations; it’s all just speculation on our part. We’re looking forward to the original poster revealing the actual reason!
