Overview
General Blower Operation
The NVE BLOWERS are severe duty vacuum
pumps, designed to be used in liquid waste
pumping systems where extended operaon
is desired. The pump incorporates a ballast
air cooling system to provide superior cooling,
allowing for extended operaon.
The air enters the intake under vacuum or at
atmospheric pressure. As the rotors rotate, a xed 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 p passes the ballast port.
The airow capacity of the machine (in ACFM) is nearly proporonal to the speed
of the machine and is nearly constant with changes in inlet or outlet pressures.
