Design

  • Compact unit
  • All components are mounted on a main frame
  • Rubber-metal elements to reduce vibrations
  • Electrical control panel wired to terminal boxes
  • Installation does not require foundation.

 

 

Compressor Stage

  • Rotary vane compressor stage
  • Fresh oil injection cooling
  • Multi-cell design principle, driven directly via an elastic coupling between the drive motor and the compressor stage
  • Suitable for compressing purified gas
  • Outstanding operating reliability
  • Dynamic oil film between vanes and the inner wall of the compressor housing
  • Low rpm and self-centering rotor

 

 

Gas Path

The gas flows through the suction line to the compressor stage. Here it is compressed as a result of the increasingly smaller volumes of the compression chambers. The compressed gas exits from a compression fitting on the compression stage through a check valve and enters the compression-side piping system.

 

Cooling

The series RVA compressors are water-cooled. The heat generated during operation is removed by cooling water, which flows through the compressor housing from the bottom to the top.

 

Drive

The compressor stage is driven directly via an elastic coupling with coupling protection between the drive motor and the compressor stage shaft. The RVA 280-610 system size compressors also have a gearbox between the motor and the compressor stage.

 

Safety Equipment and Display

  • Temperature switch to monitor the gas outlet temperature.
  • Thermometer to display the gas outlet temperature.
  • Level monitor to monitor the oil level in the lubricating oil tank.
  • Oil lubricating pump rotational speed monitor.
  • Temperature switch to monitor the gearbox oil temperature (RVA 280-610).
  • Flow rate monitor to monitor the cooling water at the cooling water outlet.
  • Thermometer for cooling water inlet and outlet.  Pressure gauge for compressor pressure.
  • Check valve on the pressure side.
