In the overhung configuration, the impeller is located at the non-drive end of the shaft (outboard of the non-drive end radial bearing). Various types are as following Overhang single stage compressors Single-stage centrifugal compressors may be configured as a beam design or with an overhung impeller arrangement. Initial cost for medium to high capacity range of single stage compressors is attractive than other types.
The Flow capacities of these types range from 1000 cfm to 300,000 cfm. Generally a single stage compressor can achieve up to a 3 to 1 compression ratio.
The compression ratio capability of the compressor is primarily a function of the impeller peripheral speed and blade geometry.
2.5 Integrally geared multistage compressors- Single Stage compressor–Ī single stage centrifugal compressor consists of a single impeller with associated guide vanes and diffuser.
