Operation & Maintenance Manual NOISE EMISSION
Maintenance Schedule
PERIOD DESCRIPTION
As Detected
COMPRESSED AIR LEAKS
Correct all compressed air leaks during the first shutdown period
after discovery. If severe enough to cause serious noise problems
and efficiency loss, shut down immediately and correct the leak(s).
As Detected
SAFETY AND CONTROL SYSTEMS
Repair or replace all safety and control systems or circuits as
malfunction occurs. No compressor should be operated with either
system bypassed, disabled, or nonfunctional.
Daily
ACOUSTIC MATERIALS
In daily inspections, observe these materials. Maintain all acoustic
material as nearly as possible in its original condition. Repair or
replace all sections that have: 1) sustained damage, 2) have
partially separated from panels to which they were attached, 3) are
missing, or have otherwise deteriorated due to severe operating or
storage conditions.
100 HOURS
FASTENERS
All fasteners such as hinges, nuts, bolts, clamps, screws, rivets,
and latches should be inspected for looseness after each 100
hours of operation. They should be retightened, repaired, or if
missing, replaced immediately to prevent subsequent damage and
noise emission increase.
100 HOURS
ENCLOSURE PANELS
Enclosure panels should be inspected at 100 hour operational
intervals. All panels that are warped, punctured, torn, or otherwise
deformed, such that their noise containment function is reduced,
should be repaired or replaced before the next operation interval.
Doors, access panels, and hatch closures especially, should be
checked and adjusted at this time to ensure continuous seating
between gasket or acoustic material and the mating frame.
100 HOURS
AIR INTAKE AND ENGINE EXHAUST
Engine and compressor air intake and engine exhaust systems
should be inspected after each 100 hours of operation for loose,
damaged, or deteriorated components. Repairs or replacements
should be made before the next period of use.
250 HOURS
COOLING SYSTEMS
All components of the cooling system for engine water and
compressor oil should be inspected every 250 hours of use.
Any discrepancies found should be corrected before placing the
compressor back in operation. Unrestricted airflow over the radiator
and oil cooler must be maintained at all times during operation.
