Compressors

  1. 1. COMPRESSORS COMPOSED BY WAQAS AHMED Facebook.com/vicky937
  2. 2. Compressor:  A compressor is a mechanical device that increases the pressure of a gas or Air by reducing its volume.
  3. 3. TYPES
  4. 4. Centrifugal compressors:  Centrifugal compressors use a rotating disk or impeller in a shaped housing to force the gas to the rim of the impeller, increasing the velocity of the gas.
  5. 5. Axial-flow compressors: Axial flow dynamic compressors are dynamic rotating compressors that use arrays of fan-like airfoils to progressively compress the working fluid. They are used where there is a requirement for a high flow rate or a compact design.
  6. 6. Reciprocating compressors Reciprocating compressors use pistons driven by a crankshaft and crankshaft can be driven by electric motors or internal combustion engines.
  7. 7. Single reciprocating
  8. 8. Diaphragm compressors A diaphragm compressor (also known as a membrane compressor) is a conventional reciprocating compressor. The compression of gas occurs by the movement of a flexible membrane instead of an intake element.
  9. 9. Rotary screw compressors Rotary screw compressors use two meshed rotating positivedisplacement helical screws to force the gas into a smaller space
  10. 10. Rotary vane compressors A rotary vane pump is a positivedisplacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity.
  11. 11. Scroll compressors: A scroll compressor, also known as scroll pump uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases They operate more smoothly, quietly, and reliably than other types of compressors .
