Chapter 9: Troubleshooting

Minor situations can occur during the operation of a HSR Compressor that requires
trouble shooting. Often these situations can be attributed to gas contaminants
(liquid and solids carryover), actual conditions different from design (improper
adjustments), unsuitable lubricant selection, or operating personnel unfamiliar
with the compressor and its setup. These difficulties can usually be addressed with
personnel training, proper lubricant selection, proper compressor adjustments,
correction of adverse operating conditions, or replacement of minor parts.
Major situations may also occur, generally during longer periods of operation.
Often these situations can be attributed to use of the compressor for purposes
different than design, unsuitable lubricant selection (generally cylinders and
packing lubrication), valves not tailored for operating conditions, or improper
operations and maintenance.
It is important to use a compressor log sheet to record inter-stage pressures and
temperatures by stage on multi-stage compressors. When inter-stage operating
conditions vary from normal it indicates trouble with one of the stages. Generally,
when the inter-stage pressure suddenly drops look at the lower pressure cylinder.
If the inter-stage pressure suddenly rises look at the higher-pressure cylinder.
The following trouble shooting cause and effect is offered as a basic guide only.
It lists the more common issues with their most probable causes. It may be
expanded to address specific package designs and actual operating conditions.
Perform lockout/tag-out procedures before performing
removal or installation of the stub shaft.
