7.2 Special Maintenance Requirements
In addition to the regular maintenance schedule, there
are some further special requirements for maintenance
of the unit based on the number of operating hours from
initial start-up:
At 200 hours of operation:
n
Check operating temperatures / pressures
n
Check chemical condition of oil
n
Change oil filter elements
n
Change oil return strainers
n
Check drive coupling
n
Check compressor / motor alignment
n
Check vibration levels
At 1000 hours of operation:
n
Check operating temperatures / pressures
At 5000 hours of operation:
n
Check operating temperatures / pressures
n
Check chemical condition of oil
n
Change oil filter elements
n Change oil return strainers
n
Change oil
n
Check drive coupling
n
Check compressor / motor alignment
At 50,000 hours of operation:
n
Compressor internal inspection
For practical reasons it is not necessary to carry out
these maintenance operations at the exact operating
hours specified. The work should, however, be carried
out slightly before rather than after the specified hours.
The calendar time taken to reach the number of
operating hours specified above will vary significantly
depending on operating schedule. If a maintenance
operation given above closely coincides with, or has
been recently been completed as, part of the regular
scheduled maintenance then the operation need not be
repeated.
