Liquid-ring compressors (FIG. 1) use the centrifugal whirling of a sealing liquid to create a series of piston-like water columns to trap gas or vapor between the impeller cells of a rotor installed eccentric to its casing.
Liquid-ring compressors (FIG. 1) use the centrifugal whirling of a sealing liquid to create a series of piston-like water columns to trap gas or vapor between the impeller cells of a rotor installed eccentric to its casing. During operation, the trapped space occupied by the gas or vapor in each impeller cell progressively decreases around the rotor. By sealing liquid being flung outward from the center of the rotation, the volume of the gas is progressively reduced. Therefore, the pressure increases, and the gas leaves the discharge port at some elevated pressure.
