I – 13. MAINTENANCE
1. GENERAL
As you proceed through this section, it will be easy to
see how simple is the compressor to maintain. By
following these recommendations, you will get long
and trouble free operation from your air compressor.
The following are general guidelines for periodical
maintanence; specific details will be mentioned in the
following chapters. Use the
Maintenance Table
for
maintenance and record keeping.
WARNING
Before attempting any maintenance work,
isolate the compressor by switching off the
power and blowing down the pressure inside all
devices, including the filters, purifier, piping
etc. If a bank system exists, isolate by closing
the appropriate valves.
2. DAILY
1. Check the oil level and fill the crankcase if
needed.
2. On gas compressors, check the seal chamber oil
level.
2. Drain the condensate from pressure vessels –if
any- and the piping network (not applicable to
individual filling stations)
3. Observe the compressor for any irregularities,
such as loose bolts, unusual noise, loose belts,
leaking pipes etc.
3. WEEKLY
1. Inspect the intake air filters to make sure they are
not clogged or punctured.
2. Clean dust and dirt from the compressor flywheel,
intercooler, aftercooler and cylinders to insure
proper cooling.
3. Check the V-belt tension. The proper tension
should allow 13 mm (
½
”) deflection with a 1 kg (2
pounds) weight applied on the center of each
belt.
4. Every 120 Hours: Change or re-fill the purifier
cartridge. Depending on the ambient conditions,
this period can be shortened or extended.
5. 300 HOURS MAINTENANCE
1. Check the pressure relief valve(s) against leaks.
2. Change the pre-filter cartridge.
3. Clean the surfaces of the intercoolers, aftercooler,
fan blades, flywheel blades.
4. If any deviation in the stage pressures is noticed,
clean all stage valves.
5. Inspect the valves; make sure there is no dirt or
carbon collection on any parts of the valve assemblies.
6. 500 HOURS MAINTENANCE
1. Change
the
oil
in the compressor crankcase.
2. Change the intake air filter catridge.
3. Clean valves; replace worn discs and springs.
4. Tighten all bolts and nuts (do not overtighten; if
not sure, use a torquemeter). See the torue
values in this manual
7. 1000 HOURS MAINTENANCE
1. Replace the o-rings and gaskets in the valve
assemblies.
2. Clean compressor valves. Replace any worn parts.
Take care to replace the cylinder covers and valve
plates in original position. All gaskets should be
replaced with new gaskets.
8. AS
REQUIRED
Check the motor or engine manual for recommended
service intervals.
Check and replace worn piston rings.
See the specific instruction sections for additional
maintenance rules for the specific compressor and
ancillary equipment delivered to your plant.
