Aux 2 Unit 1 Q2

1 / 7

What happens to the flow rate when the swash plate angle is increased in an axial variable delivery pump?

B) The flow rate remains constant

D) The pump stops functioning

A) The flow rate decreases

C) The flow rate increases

2 / 7

Which statement best describes the operating principle of an axial variable delivery hydraulic pump?

B) The pump’s pistons move axially within a rotating cylinder block, and the swash plate angle controls the volume of fluid displaced per cycle.

D) The pump relies on gravity to move fluid through the system.

A) The pistons move in a straight line within the cylinder block, and the flow rate is constant.

C) The pump uses a rotating vane to push fluid through the system at a constant flow rate.

3 / 7

Which type of control mechanism is commonly used to adjust the swash plate in an axial variable delivery hydraulic pump?

B) Pressure compensation control

A) Pneumatic control

D) Magnetic control

C) Thermal control

4 / 7

What is the primary function of an axial variable delivery hydraulic pump?

C) To control the temperature of the hydraulic system

A) To convert hydraulic energy into mechanical motion

D) To measure fluid pressure in the system

B) To convert mechanical energy into hydraulic energy with adjustable fluid output

5 / 7

What is a key advantage of using an axial variable delivery hydraulic pump in hydraulic systems?

A) It always provides maximum flow, regardless of demand

D) It is simpler to construct than fixed displacement pumps

C) It allows for adjustable flow rate and pressure, leading to energy savings and system flexibility

B) It is less efficient than a fixed displacement pump

6 / 7

How does changing the swash plate angle affect the hydraulic pump’s output?

D) It makes the pump run at a constant speed

A) It changes the direction of the fluid flow

B) It alters the flow rate and volume of liquid output

C) It increases the pressure in the system

7 / 7

Which component in an axial variable delivery hydraulic pump allows it to vary the flow rate?

A) The valve plate

D) The cylinder block

B) The swash plate

C) The piston head
