Aux 2 Unit 1 Q1

1 / 7

What is the purpose of varying the swash plate angle in an axial piston pump?

A) To adjust the pressure of the hydraulic system

C) To change the type of hydraulic fluid used

D) To cool the hydraulic fluid

B) To regulate the flow rate and volume of liquid displaced

2 / 7

What is one advantage of using a variable displacement axial piston pump in a hydraulic system?

B) It provides flexibility in flow rate, leading to better energy efficiency

D) It only works in one direction

A) It always operates at maximum capacity, which increases energy use

C) It is cheaper than fixed displacement pumps

3 / 7

Which component in an axial piston pump directly affects the piston movement?

B) The swash plate

A) The cylinder block

D) The pressure relief valve

C) The inlet valve

4 / 7

How can an axial piston pump vary the volume of liquid it displaces?

A) By changing the speed of the electric motor

C) By altering the diameter of the pistons

D) By adding more pistons to the cylinder block

B) By adjusting the angle of the swash plate

5 / 7

What are the common types of control mechanisms used for adjusting the swash plate in an axial piston pump?

B) Hydraulic, pneumatic, and cooling control

C) Temperature, magnetic, and sonic control

A) Manual, electrical, and pressure compensation control

D) Rotational, vibrational, and thermal control

6 / 7

What is the primary function of an axial piston pump?

C) To regulate the temperature of hydraulic fluid

A) To convert electrical energy into mechanical motion

B) To convert mechanical energy into hydraulic energy by displacing liquid

D) To measure the pressure in a hydraulic system

7 / 7

What happens to the volume of liquid displaced when the swash plate angle is reduced in an axial piston pump?

B) The displacement decreases

C) The pressure in the system increases

D) The speed of the pump doubles

A) The displacement increases
