What Are The Major Types Of Air Compressor?

  1. Turbo compressor
  2. Axial compressor
  3. Axial compressor of a Wright J65 jet engine
  4. Radial compressor of a Kalikow WK-1 jet engine
  5. Turbo compressor train of an air separation plant

The turbocharger (also turbo-compressor) belongs to the thermal turbomachinery. He works in the reversal of the principle of the turbine, similar in components and structure of the centrifugal pump and also promotes the respective medium by transmitting kinetic energy in the form of a swirl pulse.

In contrast to the pump, the gas is compressed in the compressor, that is, at the same mass flow, the volume flow at the outlet is lower.

The required volume change work must not be applied by a pump, which is why with the same pressure buildup, the pumping work is much lower than the compressor or. Compressor work. For this reason, steam power plants operate more efficiently than comparable power plants that run on air / gas.

  • A housing with corresponding guide devices
  • A wave with at least one
  • Impeller with blades or a directly on the shaft mounted blade row.

In the axial compressor, the gas to be compressed flows through the compressor in a direction parallel to the shaft. In the radial compressor, the gas flows axially into the impeller of the compressor stage and is then deflected outwards (radially).

With multistage centrifugal compressors, a flow diversion is required behind each stage. Generally, axial compressors deliver higher flow rates while centrifugal compressors produce higher pressures. Combined designs with their axial stage group absorb large volume flows, which are compressed to high pressures in the subsequent radial stages.

The diagonal compressors are a combination of both principles. In the frequently built single-shaft machines, the u. U. also be driven by a separate gear, the individual compressor stages are arranged one behind the other on the shaft.

The arrangement is often made so that there is a main flow direction (from the suction to the discharge nozzle), sometimes a “back to back” arrangement of individual compressor stages or stages groups is selected to compensate for the axial thrust of the shaft, so that more than a suction – or discharge nozzle results.

Another type are the geared compressors, in which the individual radial compressor stages are grouped directly around a gearbox housing around. This transmission has a central large (tooth) wheel, which drives several parallel pinion shafts, each carrying one or two wheels.

The large wheel is either directly coupled to the prime mover (motor drive) or in turn is driven by a usually lying below drive pinion (turbine drive).
