A gas compressor is a machine that increases the pressure of a gas by reducing its volume. The compression of gas naturally increases its temperature level. When the gas is air, the machine is termed an air compressor.
Types of Gas Compressors
A positive displacement compressor is a system that compresses the air by the displacement of a mechanical linkage reducing the amount (since the reduction in volume because of the piston in thermodynamics is taken into the positive displacement of the piston in the compressor system).
- Reciprocating compressors
- Ionic liquid piston compressor
- Rotary screw compressor
- Rotary vane compressor
- Rolling piston
- Scroll compressors
- Diaphragm compressors
DYNAMIC GAS COMPRESSORS
Dynamic compressors operate by continuously increasing the momentum of a gas because it flows through them and doesn’t consider a trapped volume, support the principle of imparting velocity to a gas stream and so converting this velocity energy into pressure energy.
1. Centrifugal Compressors
2. Axial Flow Compressors
3. mixed-flow compressors
Gas compressors in various applications
- In gas pipelines for the transportation of gas
- Large industrial plants require compressing for intermediate and end-product gases
- Gas turbine systems
- Underwater Submarines use compressors to store air for later use in displacing water from buoyancy chambers to regulate.
- Plastic bottle and container manufacturing industries
- Some types of jet engines for fuel combustions
- To operate the heavy vehicle Brakes
- For aircraft to maintain cabin pressurization at different altitudes.
