What impact does the level of the working fluid in the vapor-liquid separation tank of a liquid ring vacuum pump have on the vacuum pumping capacity of the pump?
What impact does the level of the working fluid in the vapor-liquid separation tank of a liquid ring vacuum pump have on the pump’s vacuum-pumping capacity? How can vacuum extraction be carried out if there is no fluid level at all?
It mainly depends on the liquid level in the host unit. If the level is too high, the gas chamber shrinks, and the vacuum pump draws in liquid, preventing it from functioning properly; if the level is too low, air can easily return, resulting in no compression and thus no operation. Therefore, it is necessary to select an appropriate sealing height
The liquid level is high, the vacuum pump is under heavy load, and the motor trips due to overcurrent. The liquid level is low, so the liquid ring cannot be formed and the pumping effect is poor.
What can cause changes in the liquid level of the host?
Under normal operating conditions, does the liquid level in the vapor-liquid separation tank affect the vacuum pumping capacity of the vacuum pump?
I’d like to ask here: are you referring to the separation tank before the pump, or the separation tank after the pump?
You are referring to vacuum units, right? Those are devices in which the pump and the separation tank behind it are combined together, with water from the separation tank flowing back into the pump to maintain the formation of a liquid ring. If the liquid level in the separator tank behind the pump is too low, the liquid ring of the vacuum pump cannot be established, and as a result it cannot operate
There is no impact; the vapor-night separation process has little to do with vacuum
Some sources state that the liquid level in the vapor-liquid separation tank can affect the pumping capacity of the vacuum pump; an excessively high liquid level can reduce this capacity
