The water ring vacuum pump is too noisy – how to solve it
Thread Content
The noise level is high, which has an impact on the occupational health of the staff. Is the noise coming from inside the pump? Is there a dedicated silencer? Export silencing doesn’t work, right?
The noise level of water ring pumps is already quite low
Due to production needs, it’s sometimes possible to have four of them running at the same time; as for the noise… is there any good solution other than putting them inside the house?
Consider replacing the dry vacuum pump
Is that the normal operating sound? Could it be the cause of the malfunction?
It’s not a fault; the gas being inhaled contains gases with lower boiling points..
I searched for some relevant information online, apart from the reasons for equipment damage. It is mainly due to cavitation; one can install pipelines to prevent cavitation and overcome the limit vacuum, and there are also relevant posts discussing this on the forum. What should be done with gases with low boiling points in the inhaled gas?
Add another stage of pump in front to increase the inlet operating pressure of the water ring pump, thereby reducing cavitation noise!
Are you referring to increasing the inlet pressure of the circulating water? Will it have an impact on the vacuum?
No. What I mean is: 1) The low inlet pressure of the liquid ring pump is the main cause of cavitation noise ； 2) A Roots pump, steam ejector, or atmospheric ejector is placed in front of the liquid ring pump; this allows the lower pressure required by the system to be maintained. When the pressure at the direct inlet of the liquid ring pump increases, cavitation does not occur in the pump.
Installing cavitation protection tubes on the distribution plate can effectively reduce cavitation
