Elliott Compressors
Thread Content
The Elliott turbine compressor model is 32M7I+SRV4-2, where 32M7I denotes the compressor and SRV4-2 denotes the turbine. What do each of these letters and numbers mean? Thank you. . .
32M denotes a nominal diameter of 32 inches for the baffle return bend. Turbine: S represents the entire rotor ； R represents the nominal diameter of the wheel ； V represents a lift-type speed control valve ；
So what does 4-2 after SRV mean? Thank you
The 4 at the end should be level 4, but I’m not sure about -2
32M7I+SRV4-2: 32 represents the nominal size of the baffle return bend, in inches; M indicates that the shell is of horizontal split type; 7 denotes a 7-stage impeller; I stands for inter-stage cooling; S refers to a fully forged rotor; R indicates the nominal diameter of the disk; V represents a lift plate-type speed control valve; 4 means there are 4 stages in addition to the first stage; -2 indicates that the first stage is a multi-stage design
