Lubercation Turbine Flashcards
What are turbine engines suppost to use as oil
Synthetic blend
What is the oil measured in
Centristoke
What is hot tank Lubrication
When the oil cooler is located in the pressure subsystem
In a hot tank lubrication system is the scavenged oil cooled before it’s returned to the tank
No
What is a cold tank lubrication system
A system where the oil cooler is in the scavenge system
What is the scavange oil system
Collects the oil after it has been lubricated the bearings and gears and returns back to the tank
What does the vent system job
To provide a slight pressure on the oil to provide for positive flow to inlet of pump
What is the air-oil separator
Removes air for the scavenged oil before it returns to the oil tank
What is the dwell chamber
Entrained air is allowed to escape from the scavenged oil
What are the types of bearings used on turbine engines
Roller
Ball
What are the types of seals used
Carbon seals
Labyrinth seals
What are carbon seals used for
Minimum leakage is allowed. Are rubbing type seals
What is labyrinth seals used for
Is a non rubbing air and or oil seal used around the main shaft bearings in gas turbines
What is a deaerator
A conponet in a turbine engine lubrication system that removes air from the scavenged oil before it is returned to the tank
What is cavitating
The creation of a low pressure in an oil pump when the inlet system is not able to supply all of the oil to the pump requires
