-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. Blower incorporate a ballast
air cooling system to provide superior cooling,
allowing for extended operation. 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.
-Air Flow Control
The airflow rate on the blower can be adjusted by changing the speed of the blower.
This can be accomplished by changing the PTO ratio, gearbox ratio, belt drive pulley
diameters or engine speed.
-Sound Level
It is recommended the operator monitor the blower while running and listen for
resonances (increased levels of noise) that may occur at certain RPM’s and operate
the blower at speeds above or below the resonance speeds to reduce excess noise.
The noise level of the blower may increase with higher levels of vacuum and RPM.
To minimize noise, operate the blower at the minimum speed and vacuum level
required to achieve the desired performance results.
