GAS COMPRESSORS
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
POSITIVE DISPLACEMENT
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).
Types-
- 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.
Types-
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.
