Chapter 8: Maintenance

Safety must always be the paramount consideration in the operation AND
maintenance of a reciprocating gas compressor.
THE DRIVER (ENGINE, ELECTRIC MOTOR, ETC.) MUST BE
STOPPED AND IF NOT UNCOUPLED FROM THE COMPRESSOR,
RESTRAINED TO PREVENT COMPRESSOR ROTATION WHILE
PRECAUTIONARY SAFETY PROCEDURES, ALONG WITH
APPROPRIATE LOCK OUT/TAG OUT MUST BE FOLLOWED.
WEAR APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
1. Isolate the compressor from any electrical power source. An electric motor
driver's switch gear must be locked out during maintenance activities.
2. Close valves blocking fuel and starting gas..Turn off the electrical supply and
ignition sources.
3. Apply mechanical lockout device to prevent crankshaft rotation.
4. Isolate the compressor from any compressed gas or rotational source.
5. Close the compressor's suction and discharge lines' isolation valves.
6. Vent process gas from the cylinders by opening the blow-down valve and vent
valve. Refer to the Packager's instructions for proper gas system(s) isolation
and venting instructions.
7. Ensure that the crankshaft cannot be turned by residual cylinder gas pressure,
running gear weight imbalance, nor the driver.
8. Shield the compressor from dirt entry when any covers are removed. Use
clean tools and lint free rags. Keep the work area clean and dry.
9. Use a suitable safe solvent for cleaning any part, and dry it thoroughly before
reassembly.
10. Use proper lifting tools and techniques when disassembling or reassembling
equipment. Refer to "Table 1"
weights.
11. Torque fasteners (studs, nuts, capscrews, etc.) to their recommended values,
