Description of machine
OPERATING PRINCIPLE
The design consists of a functional sound-
proo
fi
ng enclosure made of sheet steel and
painted with epoxy powders.
The enclosure is complete with a pre-
fi
lter kit, preventing the access of coarse
particles, which could clog the radiators
and the air
fi
lter before their life-time.
Wide removable panels and hinged doors
make all maintenance operations easily
accessible.
The base is supplied with openings that
allow for easy lifting and handling of the
compressor (See Section 4).
Standard packaging includes:
fi
xing on
wooden pallets and a cardboard box.
The Compressor
The vane compressor is a volumetric rotary
compressor consisting of a cylinder, called
stator, within which a rotor turns, which is
mounted eccentrically and at a tangent,
and by two covers. The rotor is provided
with longitudinal grooves within which the
vanes slide that are kept in contact with the
stator by the centrifugal energy.
Sealing, cooling and lubrication of all
moving parts are guaranteed by an
ef
fi
cient oil injection system that operates
due to the pressure difference between
the compression chamber and the oil
tank. Hence, no pumps are required for
lubricating oil circulation.
An oil
fi
lm on the inner stator surface
prevents direct contact with the moving
parts preventing their wear.
In the vane compressor there are no axial
forces that push the rotor against the
covers; therefore it is not necessary to
control their position with thrust bearings.
The rotor is supported by a white metal
bearing and a rolling ball bearing.
Air is drawn into the compressor though the
intake
fi
lter and intake valve
into the compressor. The air is then
compressed and discharged in a pulse
free stream.
The suction valve
The intake
valve is controlled by a speci
fi
c solenoid
valve through a hydraulic circuit, driven by
compressed air. It can adjust the quantity of
air taken into the compressor to supply the
line demand.
