Preventive Maintenance

Record Keeping

Maintenance and Repairs – Compressor Log Book
All operating compressors require periodic maintenance. Establish a maintenance
program in conjunction with any recommended startup and initial operations
checks. The program should be reviewed at regular intervals and modified as
required to address any special situations or concerns.
A maintenance logbook should be kept on each compressor. The logbook allows
for detailed records, so that maintenance costs, troubleshooting and trending can
occur. Qualified personnel should routinely review the operator's log sheets to
determine the compressor maintenance or performance trends.
Operating Conditions – Compressor Operating Log Book
Operating conditions may frequently change in the course of compressor
operation. Ambient conditions, upstream and downstream process gas changes or
upsets in addition to normal wear and tear on the compressor affect the operating
conditions.
Documentation of all operating conditions and safety shutdown points of
operating speed, pressures, temperatures, lube oil flow rates, lube oil consumption,
process gas flow rates, fuel gas or electrical power consumption, etc., provide
historical record of the package performance. Additionally, this data provides
trend lines the operator may use for troubleshooting and projected major overhaul
planning.

oil analysis

A regular oil analysis program is recommended through the oil supplier.
Compressor oil change intervals are based on operating hours or the oil supplier's
specific analysis recommendations. If the oil supplier recommends a more
frequent oil change interval than HSR compressors, follow the oil supplier's
recommendations. If the crankcase sump gets contaminated, change the
compressor oil and flush the crankcase.

Cleanliness

Pay special attention to compressor cleanliness during maintenance activities,
since construction debris and windblown dust are common problems. Whenever
access covers have been removed, keep internals protected except when actually
working on the compressor. Inspect and clean, if required, all of the compressor
components before re-installation.

inspect gaskets and o-rings

Whenever the compressor is disassembled for maintenance, gaskets and O-rings
should be replaced. If any gas pressure containing, or sealing components (crush
gaskets or O-rings) are found damaged, always replace them.
