The liquid ring pump by rotating a vaned impeller inside an eccentric to a cylindrical casing, liquid (typically drinking water) is fed into the pump and, by centrifugal acceleration, kinds a shifting cylindrical ring against the inside of of the casing. This liquid ring results in a sequence of seals in the place between the impeller vanes, which kind compression chambers. The eccentricity among the impeller’s axis of rotation and the casing geometric axis outcomes in a cyclic variation of the volume enclosed by the vanes and the ring.
Gasoline is drawn into the pump via an inlet port in the conclude of the casing. The fuel is trapped in the compression chambers fashioned by the impeller vanes and the liquid ring. The reduction in volume brought on by the impeller rotation compresses the gas, which studies to the discharge port in the stop of the casing.
