Water ring thickness issue in water ring vacuum pumps
Thread Content
When a water ring vacuum pump is in operation, how is the thickness of the water ring determined, and does it change? The outlet temperature of the gas compressed by the water ring vacuum pump in our unit is relatively high (reaching 60 degrees in summer), which results in a high inlet temperature for the compressor and affects its overall operating conditions. I am now considering whether it is possible to implement forced circulation in the vacuum pump in order to carry away heat through the heat exchange zone. Since I am not very familiar with this topic, I would like to ask whether forced circulation could lead to an increase in the thickness of the water ring, causing the motor to overload and shut down, or whether the water ring has the ability to maintain its own balance, with any excess water being returned to the water storage tank via the gas phase.
It seems that the water ring pumps used there are simply a combination of a motor and a pump; the outlet temperature is relatively high. Considerating circulation cooling for the fluid working inside the pump could be an option, and the water ring pump should be equipped with an automatic drain valve to regulate the thickness of the water ring.
