Principle Of Operation
- Gas entering via the suction port is conveyed into impeller casing A-B 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 discharge port the volume decreases as the liquid ring creates compression.
- The compression continues until the gas is discharged through the discharge port C-D. A small amount of seal liquid is discharged with the gas and it is necessary to supply make-up continuously.
- The make-up liquid also maintains the liquid ring and absorbs the heat energy of compression.
