Lube Oil Storage & Transfer Flashcards
What systems are serviced by the LO storage, transfer, and purification system?
Main turbine lube oil and feedwater pump turbine lube oil
What components make up the OS system?
2 storage tanks, a MFPT centrifuge, turbo-toc, and one transfer pump
What provides the seal water for the MFPT centrifuge?
DS system
How does the IA system interface with the OS system?
it provides air for the centrifuge cover interlock with the control panel
Where are the lube oil storage tanks located?
North yard surrounded by a concrete curb
Which lube oil storage tank holds the used/dirty oil?
“B” holds the dirty oil
Where can the OS transfer pump be operated from?
the local control panel
Where can the FWPT centrifuge be aligned?
1) recirc main lube oil reservoir
2) FPT lube oil reservoirs
3) LOSTs
4) to purify oil during transfer between the reservoirs and storage tanks
What must be done at the beginning of each centrifuge run?
the bowl must be primed with DS water
What will cause an alarm near the centrifuge?
1) the bowl loses its seal
2) low flow from the heater
3) high vibration
4) low air pressure
What will cause the breakover switch to activate an alarm and shut off feed?
bowl loses its water seal or sudden large flow of water through the heavy phase outlet that could indicate a cooler tube leak
Can the centrifuge be started with the cover open?
no, the OSHA pneumatic interlock prevents opening or loosening cover clamps when the centrifuge is running and prevents starting it with the cover open.
How many filters are in the Turbo-Toc?
3; #1 Prefilter, #2 Coalescer/Separator, #3 Polishing filter
What happens to the water that is separated from the oil in the Turbo-Toc?
it drops to the bottom of filter #2 housing and when level is high enough, a float valve opens an auto drain valve that sends the water to a drain system.
What alarms for the Turbo-Toc are in the control room?
1) high vacuum on the pump suction
2) low flow
3) High d/p across any of the 3 filters of 25psid or more
