Start The Compressor - GE H301 Series Operating Manual

64 | Chapter 5: Operation

Start the Compressor

Follow these steps to start the compressor:
1. Open the process gas discharge, by-pass, and vent/blow down valves.
2. Open the suction valve allowing process gas to flow through the compressor
package, forcing out the ambient air from the process gas system.
3. Close the vent/blow down valve to pressurize the process gas system.
4. Close the by-pass/load/recycle valve(s).
5. Open the vent/blow down valve to release the trapped process gas pressure.
6. Repeat steps 3-5 to purge the system (follow your companies policies).
7. Close the vent/blow down valve.
8. Open the by-pass/load/recycle valve(s).
9. Depressurize the process gas system to a maximum allowable starting suction
pressure, if required.
10. Use the frame and cylinder pre-lube pumps to pre-lubricate the bearings and
cylinders.
11. Start the compressor and run at not less than 700 low idle RPM, when applicable.
12. Immediately check for unusual noises, low oil pressure and level and correct.
13. Continue operating the compressor at reduced speed until the oil temperature
reaches 100°F (39°C).
14. Confirm the suction valve is open.
15. Close the by-pass/load/recycle valve(s) slowly.
16. If using a suction control valve, adjust the controller for adequate suction
pressure.
17. Adjust the driver RPM to the operating conditions.
18. Check the suction inter-stage and discharge pressures.
19. Verify the gas pressures/temperatures and oil pressure/temperature are within
operating condition limits.
20. Confirm all the pressure/temperature safety switches are properly set.
Failure to confirm that each cylinder's high discharge gas
temperature alarm and shutdown settings are functioning
properly for its normal operating conditions can result in
equipment damage.
