Major types of pneumatic devices (Air compressors and pneumatic tools constitute the principle classes of pneumatic devices; An air compressor is a power-driven machine for compressing air from some initial intake pressure (usually atmospheric) to a higher pressure; two main types: positive displacement; and velocity, or dynamic; the dynamic type may be subdivided into centrifugal type (with flow through a rotating runner or rotor primarily in a radial direction), the axial-flow type (with flow through a runner primarily in a direction parallel to the axis of rotation), and the fluid-jet type) Encyc. Brit., at Compressor (Device for increasing the pressure of a gas by mechanically decreasing its volume; Centrifugal compressors increase the kinetic energy of the gas with a high-speed impeller and then convert this energy into increased pressure in a divergent outlet passage called the diffuser. Centrifugal compressors are particularly suited for compressing large volumes of gas to moderate pressures) Mechanical engineers' handbook (1998) p. 1728, Compressors (Compressors used in gas turbines are of the dynamic type, wherein air is continuously ingested and raised to the required pressure level. Centrifugal compressors are usually chosen for machines of below 2 or 3 MW in output, where their inherent simplicity and ruggedness can largely offset their lower compression efficiency. Such compressors feature a monolithic rotor with a shaped passage leading from the inlet circle or annulus to a volute at the out radius; two or more rotors can be used in series to achieve the desired pressure ratio) Raitor, T., and W.

"Latest techniques and practical notes on anti-surge systems for centrifugal compressors." Australian journal of mechanical engineering, v. 10, no. 1 (2012): 81-90, abstract (The operating range of process centrifugal compressors is limited by an instability range commonly called "surge," which occurs during low flow or high head conditions) |
