  • Discharge pressure: up to 0.83 MPa (8.46 bar)
  • Drive power: 200 kW

COMPRESSIBLE GASES

APPLICATION

Compressor system
6VV-32/7

The rotary screw compressors are volumetric machines, horizontal, single-stage, oil-injected, driven by an electric motor via flexible coupling. The compressor includes a casing, primary and secondary rotors, radial thrust bearings and seals.

The basic models can be modified in accordance with the customer requirements.

DESIGN FEATURES AND ADVANTAGES

  • Lubrication system: circulating, under pressure
  • Unloading device for the thrust bearings
  • Lubrication oil: TP-22s, KP 8s (for turbines); for the winter period - hydraulic spindle oil AU with additives
  • Lubrication oil cooling: water or air coolers
  • Automation system eliminates the constant presence of personnel and provides complete system control, basic parameters monitoring and emergency events protection
  • Operation at ambient temperatures from -40 to + 40 °C
  • Advantages in comparison with reciprocating compressors:
    • Lower maintenance and repair cost
    • Smaller dimensions
    • Uniform air supply (no air receivers are necessary)
    • Capacity control within 10 to 100 % range
    • Absence of the foundation

INSTALLATION

  • Compressor systems for permanent building of compressor station
  • Hangar version for installation in an easily-constructed prefabricated building including engineering systems.
  • Compressor systems for outdoor installation

SCOPE OF SUPPLY

  • The compressor system, consisting of a rotary screw compressor, electric motor, coarse and fine oil filters, piping, control valves mounted on a common base frame serving as a an oil tank
  • Oil cooling unit with oil cooler, electric motor, fan, valves and piping
  • Remote control board
