(1) Interconnecting cooling water between drive shaft bearing housing and the
two oil reservoirs. Mechanical seals are used throughout.
(2) Water cooled only at drive shaft bearing housing. Rotor seals are slinger
type and a mechanical seal on the drive shaft.
DESCRIPTION
Kinney Vacuum Boosters are lobe type, positive displacement units,
designed with extra heavy shafts and bearings to permit high power
input. They incorporate a unique rotor profile in which all gas joints
or mating surfaces are sealed vacuum tight.
Unit construction consists of two figure eight shaped rotors enclosed
in a precision machined housing supported at each end by precision
bearings. The power drive turns the drive rotor directly and rotates
the driven rotor by means of specially forged, heat treated, crowned
and ground precision helical gears.
Efficient and effective vacuum pumping is accomplished by
trapping a volume of gas at the booster inlet and between each rotor
and the booster housing. This volume of gas is quickly and cleanly
evacuated by the fast revolving rotors which carry the air to the
exhaust side of the booster where the air is then discharged to the
backing pump.
