USING THIS MANUAL
This manual covers the following types of
compressors:
Ambient Air Compressors
- these are compressors
whose inlet source is the ambient air surrounding the
compressor.
Air Boosters
- these are compressors that compress
air that is taken from a source other than the ambient
air. Generally the inlet air source is at an elevated
pressure, but vacuum applications can also be
accomplished. The inlet air is usually taken from
customer’s existing plant air system.
Gas Compressors
- These are compressors pumping
any gas other than air.
Ensure that you know what type of compressor you
have before using this manual. If the instructions for
the different types of compressors differ, this will be
noted in the manual.
INSPECTION AFTER EXTENDED
STORAGE
If the compressor has been out of service for an ex-
tended length of time, verify that the cylinder bores and
valve pockets are free of rust and other debris. Inspect
the crosshead bores for signs of rust.
Drain the oil from the crankcase and remove the in-
spection cover plate. Inspect inside the crankcase for
signs of rust or contamination. Clean and/or replace
parts if they exhibit signs of corrosion. Re-
fi ll the
crankcase with the proper weight and amount of oil.
Squirt oil onto all bearing areas and ensure all bear-
ings have fresh oil.
Squirt oil onto the piston rod oil scrapers by removing
the oil scraper cover. Apply enough oil to ensure that
the crosshead cylinder bores receive oil. Remove the
oil scraper case if necessary to ensure oil is applied to
the crosshead bores.
Rotate the unit manually to ensure everything rotates
smoothly and no interference or friction can be felt.
COMPRESSOR SPEED
The lubrication systems of Hycomp model compressors
are designed to operate at speeds of 400 RPM and
above. Do not operate below 400 RPM without
consulting factory.
Hycomp compressors should not be run at speeds
above 825 RPM. While these compressors have been
operated at speeds in excess of 800 RPM, reduced
volumetric efficiencies and shortened valve and
piston ring life result. Hycomp recommends keeping
compressor speed below the maximum recommended
for optimum service life and warranty compliance.
CRANKCASE LUBRICATION
Hycomp compressors ship with HYSYN SAE 30/ISO
68 synthetic compressor oil in the crankcase, unless
otherwise requested. All Hycomp compressor models
have fully pressurized crankcase lubrication system
fed by a gerotor type constant pressure oil pump,
with the exception of the ‘A’ block compressors which
are splash lubricated. With the HySyn, oil change
requirements are every 8,000 hours of run time or
12 months, whichever occurs
fi rst. In any case, oil
should be changed whenever the oil becomes visibly
contaminated. Check oil level weekly on continuous
run units. Oil level should be maintained between the
two marks on the oil dip stick located on the side of the
running gear or a small air bubble on top of the oil level
gauge located on the oil pump side of the “F” block.
Do not
fl ush the crankcase with solvents, as this will
dilute the oil. All pressure oil lubricated compressors
come standard with a spin-on oil
fi lter. This fi lter must
be replaced at the same time the oil is changed.
When an alternate oil is required, Hycomp can also
supply HYLUBE, a single viscosity non-detergent R&O
compressor oil, available in several standard viscosities
for different ambient conditions. In this situation, the
oil
fi lter and oil change requirement is 2,000 hours of
run time or 6 months, whichever occurs fi rst.
Oils come in several viscosities suitable for different
operating conditions. See Table 3 below for SAE oil
viscosity recommendations and Table 4 for crankcase
capacities.
At ambient temperatures below 0°F (-18°C), a
crankcase heater must be installed. Hycomp
recommends a 70°F (21°C) thermostat setpoint, with
SAE30/ISO68 oil.
NOTE: DO NOT MIX SYNTHETIC OIL WITH
TRADITIONAL COMPRESSOR OIL.
