Removal Of Oil Separator For Inspection Or Replacement
:
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
1.
Be certain unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, lockout and tagout power supply to the starter.
3.
Remove screws holding the top plate to the separator housing. Lift the top plate from the
separator housing.
4.
Lift the separator from the separator housing.
5.
Inspect and/or replace the separator as necessary. Be sure the o-ring is not damaged. Before
installing (or reinstalling) any separator apply grease to the o-ring. Oil will be wiped off by the
chamfer and the o-ring could be damaged.
6.
Remove any gasket material adhering to top plate or separator housing, and install new gasket.
7.
Lower the separator into the housing and center the separator on the chamfer. Press separator
down into the housing. Do not use excessive force as separator damage can occur.
8.
Place the spacer on the indent in the separator. Seat the top plate to the separator, spacer and
separator housing. Install and tighten all cap screws.
9.
Run the unit and check for leaks.
COMPRESSOR OIL SYSTEM CHECK
- The following readings are based on ambient temperature of
80
°
F (27
°
C) for air-cooled oil cooler and 80
°
F (27
°
C) inlet water on water-cooled oil cooler, with the
system in good condition. Compressor should be at operating temperature at the time of checks. One-
half hour of loaded operation is usually sufficient to reach level-out operating temperatures.
Air and Oil Discharge Temperature
- 165
°
F to 195
°
F (74
°
C to 91
°
C) - Read at gauge on the
instrument panel or check with a thermometer at the discharge housing.
Compressor Oil Inlet Temperature
- 150
°
F to 160
°
F (66
°
C to 71
°
C) - Install a tee at the oil filter outlet
and check with a thermometer.
Oil Inlet Pressure
- Check at the fitting in the line near the compressor oil inlet. With air receiver
pressure at 100 psi (6.9 bar), oil inlet pressure should be 55 psig to 60 psig (3.8 bar to 4.1 bar).
