Abstract
The liquid ring compressor comprises a cylindrical casing containing an impeller the axis of which is offset from the axis of the cylindrical casing. At least one end of the cylindrical casing is provided with a distribution plate and relative closure cover, the distribution plate comprising a suction aperture, a discharge aperture and a feed aperture for the operating liquid. The distribution plate is of small thickness and is constructed from sheet steel. The relative suction aperture and discharge aperture can have sharp edges and be obtained by -punching or by plasma or laser cutting.
Claims13
A liquid ring compressor comprising:
- a cylindrical casing having a first wall with an inner surface and an opposed second wall with an inner surface;
- an impeller contained within said casing, an axis of said impeller being offset from an axis of the cylindrical casing;
- a distribution plate having a useful diameter, a portion of said distribution plate being arranged between said inner surface of said first wall and said inner surface of said opposed second wall, said portion constituting said useful diameter of said distribution plate;
- and
- a relative closure cover provided at least on one end of the cylindrical casing, outside of said distribution plate, the distribution plate comprising a suction aperture, a discharge aperture and a feed aperture for passage of an operating liquid, wherein said suction aperture and said discharge aperture have sharp edges, and wherein a ratio of said useful diameter of said distribution plate to a thickness of said distribution plate is greater than 50, and wherein a plurality of ribs support and maintain said distribution plate planar.
A liquid ring compressor comprising:
- a cylindrical casing having a first wall with an inner surface and an opposed second wall with an inner surface;
- an impeller contained within said casing, an axis of said impeller being offset from an axis of the cylindrical casing;
- a planer distribution plate having a useful diameter, a portion of said distribution plate being arranged between said inner surface of said first wall and said inner surface of said opposed second wall, said portion constituting said useful diameter of said distribution plate;
- and
- a relative closure cover provided at least on one end of the cylindrical casing, outside of said distribution plate, said cover being structured and arranged for supporting and maintaining said distribution plate planar, the distribution plate comprising a suction aperture, a discharge aperture and a feed aperture for passage of an operating liquid, wherein said suction aperture and said discharge aperture have sharp edges, and wherein a ratio of said useful diameter of the distribution plate to a thickness of said distribution plate is greater than 50 and is constructed from sheet metal.
