OVERVIEW
General Blower Operation
The NVE BLOWERS are severe duty vacuum pumps, designed to be used in
liquid waste pumping systems where extended operation is desired. The
pump incorporates a ballast air cooling system to provide superior cooling,
allowing for extended operation.
The air enters the intake under vacuum or at atmospheric pressure. As the
rotors rotate, a fixed volume of air is moved along the wall of the cylinder
towards the exhaust where the pressure and temperature of the volume of
air increases. If the intake air is below atmospheric pressure, cooling air will
be drawn in when the rotor tip passes the ballast port.
The airflow capacity of the machine (in ACFM) is nearly proportional to the
speed of the machine and is nearly constant with changes in inlet or outlet
pressures.
