| PRINCIPLE OF OPERATION |
| |
 |
Gas entering via the suction port is conveyed
into the impeller casin AB and trapped in the space between
two impeller blades. As the impeller rotates - eccentrically
to the liquid ring and casing - the volume between the
blades increases creating vacuum. As the cycle progresses
towards the discharging port the volumn decreases as the
liquid ring creates compression. This compression continues
until the gas in discharged with the gas and it is necessary
to supply make-up continuously. This make-up liquid also
maintains the liquid ring and absorbs the heat energy
for compression.
I = Suction phase
II = Compression phase
