Hydraulic system components

Question 1

Describe a reservoir

Answer 1

A space set aside within a component to hold a supply of Hydraulic fluid

allows for thermal expansion and escape of entrapped air

2 types - pressurised and un pressurised

Question 2

What type of powered pumps are on aircraft

Answer 2

Gear and piston

Question 3

name the 2 categories of pumps on aircraft

Answer 3

Powered and hand pump

Question 4

Describe a filter

Answer 4

Removes contaminants in a hydraulic system

Question 5

Describe a cooler

Answer 5

Cools the Hydralic

Question 6

what are the 2 types of selector

Answer 6

Linear and rotary

Question 7

what is an accumulator (Peada)

Answer 7

Ensures instant response to selection

Provides emergency operation

Dampens shocks from pressure fluctuation

Absorbs pressure rises from thermal expansion

Allows for ground operation

An accumulator is used to maintain a preset
system pressure.

stores pressure

Question 8

Describe an actuator

Answer 8

The portion of the system that does the work.

An actuator is a component that is responsible for moving and controlling a mechanism

the bit that actually does the moving

Question 9

Describe the 3 types of actuator

Answer 9

Single acting (straight line movement, hydraulic pressure moves it and a spring moves it back, used on brakes)

double acting (can be used in two directions such as raising and lowering landing gear)

Rotary (converts linear motion of individual pistons into rotary motion)

Question 10

Describe the two categories of actuator

Answer 10

Linear and rotary

Question 11

Describe a pump

Answer 11

Hydraulic power is transmitted by movement of a pump
