DESCRIPTION
2.1 INTRODUCTION
The design of the Sullair TSR-32 compressor unit is
a two stage, positive displacement, flood lubricated
one. A complete package includes the:
d discharge systems
Although the compressor requires no inspection of
connectors, and the enclosure should be inspected
and maintained in accordance with the procedures
and recommendations in this manual.
2.2 COMPRESSOR
COMPONENT DESCRIPTION
Refer to Figure 2-1 use a fan to draw outside air into
the enclosure, cooling the motors, the combined
radiator fluid cooler, and air aftercooler. This hot air is
then vented out thru enclosure exhaust duct work.
The TSR32 comes equipped with a fluid filter, air/oil
separator(s), control valves, and an inlet air filter.
Fluid is injected into the compressor, and mixes
directly with the air as the rotors turn which
compresses the air. The fluid flow has three basic
functions:
1. As a coolant, it controls the air temperature
rise normally associated with the heat of
compression.
2. Seals the clearance paths between the
rotors and the stator, and also between the
two rotors.
3. Provides a lubricating film between the rotors
allowing one rotor to directly drive the other,
which is an idler.
After the air/fluid mixture is discharged from the
compressor unit, the fluid is separated from the air.
At this time, the air flows through an aftercooler and
separator, and then to the service line while the fluid
is cooled and filtered in preparation for reinjection.
CAUTION
Use only one type of a recommended com-
pressor lubricant. Adding a different one, or
mixing lubricants can cause damage and/or
malfunctions, and will void the compres-
NOTE
The compressor requires no internal
inspections or maintenance actions. Open-
warranty. (This does not apply to the shaft
seal which is replaceable.)
