Compressors and compressors

compressor compresses the air sucked in from the atmosphere to the working pressure. The compressor has a suction filter that separates the dust and other particles from the sucked air.

Considering the compression method, we distinguish compressors:

Lobe - They draw air into the compression chamber, then close, compress and pump compressed air into the tank. Displacement compressors are divided into:

  • Piston compressors
  • Screw compressors
  • Diaphragm compressors - They compress air through a tight and tight membrane. They produce compressed air that is free of impurities. They are great above all in supplying medical equipment as well as in the food industry. This type of diaphragm compressor is maintenance-free and reaches an operating pressure of up to 10 bar.
  • Rotary compressors - At 2-stage compression with cooling, they create an operating pressure of up to about 7 bar. These compressors work quietly. If oil is introduced into the compression chambers during compression, a pressure of up to 10 bar can be achieved in single-stage rotary screw and multi-chamber devices. The oil is used to lubricate, cool and seal the impeller.
  • Rotary multi-chamber compressors - Air is drawn in through the filter and suction valve. During compression, oil is injected into the chambers, which separates from the air in an air-oil tank before air is transferred to the network. After cooling and filtering, the oil is injected again.

 

flow - are also known as turbines. They suck and accelerate atmospheric air through wheels with blades or propellers. The kinetic energy of the stream in the connected tank is transformed into the potential energy of compressed air. These compressors are primarily characterized by high efficiency. We divide flow devices into axial and radial compressors.
