8. STANDARD COMPONENTS AND SUBSYSTEMS [Air/Oil/Water Flow]
⑻ Air intake filter
The air intake filter is a dry type for easy cleaning or
replacement.
⑼ Fan
Air-Cooled
The low noise cooling fan cools the cooler, exhausts
the hot air within the enclosure, and exhausts the
internal compressed air that is released to
atmosphere during the unloading (purging) process.
Water-Cooled
The small cooling fan cools the inside of the
package, and exhausts the internal compressed air
that is released to atmosphere during the
unloading (purging) process.
※ The indication in the ( ) is for Vtype.
⑽ Control panel
The control panel employs a printed circuit board
on which a microprocessor is mounted to achieve
easy operation. The air compressor can be operated
remotely.
⑾ Enclosure
The enclosures are attached with the sound
absorbing materials. The front and left enclosure
panel includes a door that enables easy maintenance.
Intake air is compressed and heated by the 1st stage
airend and pressure builds up to approximately 29 psi
(0.20MPa) The heated air is cooled down by the
intercooler and then further compressed and heated by
the 2nd stage airend as pressure builds up to the rated
pressure level of the air compressor. The reheated air
flows through the check valve to the aftercooler, where
the compressed air is cooled down and then discharged
to the plant compressed air piping.
8.2 Air/Oil/ Water Flow
Compressed Air Flow
Oil Flow
Cooling Air Flow
The oil sump is located in the bottom of the gear case.
Oil is sucked through an oil strainer (oil strainer has a
100-mesh filter screen) by the oil pump and is
hydraulically fed to the oil cooler where it is cooled.
During the cooling process, oil flows through the high-
precision oil filter and is then injected onto the bearings
of the 1st and 2nd stage airends as well as the stepup
gears. Oil returns to the oil sump, where it continues
to circulate through the system.
The cooling fan removes the heat from the air-cooled,
oil
cooler, intercooler, aftercooler and Hi-precooler, and
this heat exchanged air is
exhausted through the air
exhaust grill on the top of the enclosure.
Cooling Water Flow
Incoming water cools the intercooler, the water jackets
of the airends, the aftercooler and the oil cooler. Refer
to “Cooling Water Flow Diagram” for the detail of
cooling water flow (
see the flow diagram from next
page).
