Rotary Blades

Rotary Blades

Description and applications: Using an eccentric rotor and mobile blades makes it possible to offer an effective solution where high pressures are required (within low pressures) and with considerable flows; it is used in Cogeneration processes as well as in different Industrial Processes (Pneumatic Transport, Agitation, Slurry, Glass...)

Operating Principle

Operating Principe Rotary BladesThe rotary compressor is made up of a cylindrical stator, inside of which a rotor, supported at its ends by two bases, rotates. This eccentrically fixed rotor has some slots where the vanes that slide over the internal surface of the stator are housed.

The vanes form a set of cells, the volumes of which gradually increase from the intake port and which, afterwards, gradually decrease down to the impulsion/drive port.

When the rotor is rotating the vanes move outwards, under the action of the centrifugal strenght, and they get into contact with the internal surface of the stator.



ATEX Solutions

For the intake or compression of combustible gases, such as biogas or methane gas, there is a complete range of airtight side channel blowers with the following characteristics:

  • Body and impeller manufactured entirely from spark-proof aluminium alloy.
  • The parts that come into contact with the gas are impregnated with Loctite.
  • Sealed ends.
  • Shaft sealed with a lip seal that does not require lubrication.
  • Electric flame-proof engines, with a minimum protection class of EEx-d IIB T.3-IP 55. The engines comply with NEMA and SABS regulation and other Standards that can be supplied upon request. For engines of powers of up to 4KW, the machines are manufactured as the version named “MONOBLOC”.

In this version the engine is joined to the body of the machine by a flange; the impeller which is dynamically balanced, is fastened onto the engine directly.
