great damage to personnel and property, a proper
maintenance schedule must be created and rigorously
adhered to. Table 7 contains a maintenance/inspection
schedule for compressors housed within a weather
proof building, with relatively clean inlet conditions
(no acidic components, fi ltered to 0.1 micron) and
75°F ambient temperatures, running 8 hours per day.
Time frames may need to be shortened in harsher
environments.
Contact the factory or your closest authorized Hycomp
dealer for questions about designing a PM schedule
to fi t requirements differing from the listed conditions.
Reasonable judgement in the frequency of maintenance
and the stocking of spares must be exercised by the
customer. Facilities that cannot afford to be shutdown
without excessive costs or hardships must provide a
more rigorous schedule and larger quantity of spares
than facilities that can do without the compressor for
a short period of time.
The gas packings need only periodic inspection
once the compressor has been broken in. As the
packings are the heart of the leakage control system,
it is imperative that they not be allowed to deteriorate
beyond reasonable limits. Once the lifetime of the
packings are known in an application, they can be
replaced prior to failure.
