3. Start-up
If a Sundyne supplied control panel is to be used with the Sundyne LMC/BMC compressor, use the
control panel recommended start-up procedure in addition to the steps below. Before starting the
LMC/BMC compressor, complete the following procedure in the order in which the steps are
provided:
Step 1:
Make sure that the driver has been serviced as per manufacturer recommendations.
Check motor rotation before installing coupling.
Step 2:
For the auxiliaries: Check the connections of the utilities; verify that the auxiliary piping
meets the requirements shown in the Outline Drawing.
Step 3:
Install flushing screens in all field-assembled piping connections. Clean these screens
prior to commissioning. Check frequently for cleanliness and clean as needed.
Step 4:
Drain any liquids (blow-down) from the compressor and inlet pipe.
Step 5:
Prime the lubricating system, as follows:
•
Fill the oil reservoir with lubricating oil in accordance with the Field Engineering
Bulletin Gearbox Lubricant Recommendations.
•
Add oil as necessary through the fill opening.
•
With wet sump compressors, add oil as necessary until the oil level stabilizes at
the top of the bull’s eye in the sight glass. With dry sump, check oil level at
reservoir sight glass.
•
Start the auxiliary lubricating pump, and run it until the oil reaches the correct
pressure and temperature. Add oil as necessary until the oil level stabilizes 3/4
of the way from the bottom of the sight glass.
•
Allow lube pump to operate for at least 30 seconds with a minimum of 7 psig
(0.492 kg/cm^2) indication prior to starting the main driver.
Step 6:
Turn on the cooling water to lubrication systems heat exchanger (if applicable), or turn on
air cooled heat exchanger. Verify high points (e.g. heat exchanger and filters) have been
vented.
Step 7:
For double seal configurations, the buffer system must be pressurized to the pressure
specified on the spec sheet and on outline drawings prior to pressurizing the unit.
Step 8:
Charge the compressor with process gas.
Step 9:
Start compressor, following process control startup procedures.
Step 10:
Once the gearbox oil temperature has stabilized, adjust cooling water supply until the oil
temperature to the bearings is 120º - 160ºF on units equipped with water cooled heat
exchangers. Maximum recommended temperature is 180ºF.
