Integrally Geared High Speed Compressors
Low-flow, high-head, integrally geared compressors are high-speed, gear-driven, single-stage/multi-stages, overhung compressors. Integrally geared compressors are characterized by compact and high efficiency machines, which are widely used in modern processing industries. Multi-stage integrally geared compressors contain gears, with the wheel gear and the multiple pinion gears on the outside of it driving multiple impeller shafts. By changing each of the gear ratios, it is possible to operate each impeller at the optimal speed. The impeller is mounted directly to the gearbox output shaft. There is no coupling between the gearbox and compressor; however, the gearbox is flexibly coupled to its driver. The compressors may be oriented vertically or horizontally. Low space occupancy and short maintenance time is some of the main advantages of this type of compressors.
