    摘要： A modular liquid ring pump has a liquid ring overload protection system including a passage from a working chamber directly to the pump discharge passage and a mechanical relief valve configured to release liquid from the working chamber during compressor overload. The liquid ring pump, when configured to have two stages, has an inter-stage by-pass system that includes an opening in an inter-stage passage and a pressure sensitive mechanical valve that allows the discharge of a first stage compressor to flow directly to the pump discharge at start up or during low pressure operation. The liquid ring pump's modular construction may be easily configured from a single stage pump to a two-stage pump and vice versa by using the same bearings, head, and drive system and only changing the body, cone, and rotor.

    摘要： A liquid-ring, rotating-casing compressor comprises a shaft carrying an impeller having a core and a plurality of radially extending vanes rotatably coupled to the shaft for rotation around a first axis, and a tubular casing mounted for rotation relative to the impeller around a second axis that is parallel to and offset from the first axis. The casing and impeller define a compression zone wherein edges of the vanes rotate in increasing proximity to an inner surface of the casing and an expansion zone wherein edges of the vanes rotate in increasing spaced-apart relationship along an inner surface of the casing. An inlet port communicates with the expansion zone, an outlet port communicates with the compression zone, and a drive imparts rotating motion to the casing. The eccentricity ecr of the casing relative to the impeller is between about (1−c)/4 and (1−c)/9, preferably less than half (1−c)/3.
