Rotary-screw compressors are commonly available in the 5 through 500 HP range and can produce air flows in excess of 2500 SCFM. While the pressure produced by a single-stage screw compressor is limited to 250 PSIG, a two-stage screw compressor can deliver pressures of up to 600 PSIG.
Compressor. A small stationary high pressure breathing air compressor for filling scuba cylinders. Natural gas compressor at a gas well. High pressure reciprocating compressor from Belliss and Morcom, used in the bottling industry. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
On civil turbofans, the first stage of the LP compressor is often a single-stage fan. If the HP compressor pressure ratio exceeds about 4.5:1, then the unit will probably have variable geometry (i.e. variable stators) on the first few stages, to make the surge line on the compressor map more shallow, to accommodate the shallow working line.
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
Supercharger. In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement . The current categorization is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft ), as ...
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil -based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow ...
