Abstract

707,616. Centrifugal . compressors and pumps. ESCHER WYSS AKT.-GES. Jan. 23, 1952 [Jan: 24, 1951], No. 1884/52. Class 110(1) A multi-stage centrifugal compressor or pump has at least one stage wherein the working medium passes from the rotor into a large number (i.e., ten or more) of diffusers and thence into a number of angularly spaced volutes, each of which takes the discharge from at least two of the diffusers. In the compressor shown in Fig. 5, each of two pairs of volutes 15, 16 and 17, 18 has a common outlet 19 or 20. A ring of diffuser passages 2 is provided. A common outlet may be provided for more than two volutes. In alternative constructions, the volutes are separate from one another, with separate outlets. The volutes may be of reduced cross sectional area, so that the total cross-sectional area is the same as in a construction using a single volute. The volutes of an intermediate stage of a compressor may each be connected to a separate intercooler. A two-stage compressor is described, in which each of the four volutes of the first stage is connected by way of a separate return channel to the inlet of the second stage. The separate volutes of a compressor may be connected to the combustion chambers of a gas turbine.
