LUBRICATION SYSTEM
Friction is caused by one surface moving on or against another
surface. In an engine this friction can produce excessive heat and wear.
In an engine we use lubricating oil to reduce friction. We use the
terms ‘to lubricate’ or ‘lubricating’ when oil is placed on metals so that the
surfaces become smooth and slip on each other without excessive friction.
The oil between the moving parts prevents wear caused by friction.
Another reason why we use oil is to aid in engine cooling. The engine gets
hot because of burning fuel. The oil aids in engine cooling by carrying
away heat caused by the burning fuel.
We can then say that the purpose of an oil system in an aircraft is to
reduce friction and help in engine cooling.
The principal parts of an oil system are the oil tank, pumps, oil
filter, and oil temperature and pressure devices. Some old types of
aircrafts may also have an oil quantity gage. Some modern aircrafts have
only an oil pressure gage.
The oil tank stores the oil supply. A supply pump sends the oil under
pressure to the engine. The oil drains to the sump.
The scavenge pump returns the oil to the oil tank. This circle of flow
is called circulation. A liquid circulates if it returns to its container.
