15.10 LUBRICATION SYS Flashcards
what does the lubrication system do
distribute oil to engine bearing compartments and gearboxes
the engine lubrication system can be classified as what 2 things
full flow system, constant pressure system
what is the simplest type of oil supply system
full flow
what prevents oil pressure in the lubrication system getting too high
pressure relief valve
what can the constant pressure system also be called
regulated pressure system
what valve does the constant pressure system have
pressure regulating valve
what are the basic lubrication systems subsystems
oil reservoir, scavenge system, vent system, monitoring system
what are the oil systems subsystems
storage, distribution, indicating
what are the 2 ways to fill the oil tank
gravity, pressure
what are the 2 most common oil pumps
the gear pump, the gerotor pump
why are oil filters and screens used
to clean the oil passing through
what are the 2 main types of oil cooler for turbine engines
fuel cooled oil coolers, air cooled oil coolers
what does the breather do in the external gear box
removes air from the system
what two indicating systems are used for monitoring
capacitance transmitter, reed switch transmitter
what does SOAP stand for
spectrometric oil analysis programme
in the APU what used to gain information about the oil condition
magnetic chip detector
on engines with anti-siphon how long do you wait before checking the oil
5 - 20 minutes
