Is there a check valve at the inlet of the liquid ring pump? What causes the rhythmic sound at the inlet while it’s in operation?
There is a one-way ball or intake valve disc inside the pump
Two types: too large fluctuations in traffic volume； It’s broken
Do you mean a water ring vacuum pump by liquid ring pump here?
So it can be understood that rhythmic sounds are a normal phenomenon, right? I would also like to ask you: as the final vacuum extraction device at the top of a pressure reduction tower, what is the typical inlet pressure for it?
Yes, a mechanical vacuum pumping device for pressure reduction at the final stage.
The traffic has remained fairly stable, but there are frequent rhythmic noises; at times, however, no noise is heard at all.
It seems the water circulation volume is too high; let’s reduce it a bit and give it a try
The water ring vacuum pump does not have a check valve at its inlet; there is a rhythmic noise at the inlet during operation. First, adjust the flow rate of the working fluid to see if that helps, and secondly, check whether any internal components are loose or if one of the blades is broken.
Liquid ring pumps generally have check valves to prevent backflow when the pump stops.
There is no problem with the pump body; it’s the inlet pipeline that makes noise.
