ROTARY PUMP FOR LIQUID AND GASES

 

This machine – (displacer pump) is cylindrical turning crowd freely all around one's axis. Fixed is situated concentrical is in relation to cylindrical chamber off-centre on rampart, which. When rampart turns crowd rolls after wall of chamber. In cylinder oscillatory uncinate barrier is.

Advantage and advantage in relation to pistons' machines:

  1. Easiness boiling, elimination of tremblings;
  2. Small intensity of lubricating;
  3. High maximum speed;
  4. Lack of dead space;
  5. Higher volumetrical efficiency about ca. 20%;
  6. Higher thermal efficiency about 20-30%;
  7. Smaller quantity part and use up oneself them;
  8. Whole turn of rampart (360o) is cycle of compressing, pulsation of medium at high pressure does not step out practically;
  9. Possibility of blocking of (graduating);

  10. It it was been possible to construct it as:

  • Pump for every liquid;

  • Compressor for gases;
  • Vacuum compressor;
  • Combustion engines;

Such how on picture working at us from 14 years compressor from attention onto limited endurance of cylinder works with following parameters:

  1. Power supply current 220V, recruitment of power 0,65kW;
  2. Efficiency 4,2 m3/h at pressure 5 bar;
  3. Regulated range of work to 10 bar;
  4. Reservoir of air – to 5 litres;
  5. Drying airs and automatic regeneration;
  6. Dried air from oil and mechanical dirts;
  7. Point of dew – 45oC;
  8. Intensity of noise – 50dB;

The same compressor, with this engine and unchanged pressure of crowd onto cylinder she reached pressure 75 bar.
