Aux 1 Unit 5 Q4

1 / 12

What role do the vanes play in a vane-type pump?

A) They create a vacuum to draw fluid into the pump

B) They extend from the rotor to trap and move fluid through the pump

C) They filter the fluid before it enters the pump

D) They provide structural support for the pump casing

2 / 12

What is the primary function of the rotor in a vane-type pump?

C) To filter out impurities from the fluid

B) To rotate and drive the vanes within the pump

A) To seal the pump casing

D) To control the pump’s temperature

3 / 12

How does the design of a vane-type pump contribute to its efficiency in handling low-viscosity fluids?

D) The vanes are designed to wear down quickly for easier replacement

A) The vanes create a high-friction environment that helps move thick fluids

B) The vanes provide a smooth, continuous flow with minimal leakage or slippage

C) The pump operates at extremely high temperatures

4 / 12

Which of the following best describes the casing in a vane-type pump?

D) It serves as a reservoir for the pumped fluid

B) It provides the outer structure that contains the rotor and vanes

A) It houses the impeller

C) It filters the fluid being pumped

5 / 12

What would likely happen if the vanes in a vane-type pump did not maintain contact with the casing?

B) The pump would fail to move fluid effectively, leading to reduced flow or no flow at all

C) The pump would overheat due to increased friction

A) The pump would operate more efficiently

D) The fluid would leak out of the inlet port

6 / 12

What is a common application for a vane-type pump?

D) Pumping highly corrosive chemicals

B) Pumping gasoline or other low-viscosity liquids

C) Handling solid particles in a fluid stream

A) Pumping highly viscous fluids

7 / 12

What role does centrifugal force play in the operation of a vane-type pump?

C) It increases the temperature of the fluid being pumped

B) It keeps the vanes extended and in contact with the casing to maintain a seal

A) It helps the vanes retract into the rotor

D) It reduces the wear on the rotor

8 / 12

What is the purpose of the outlet port in a vane-type pump?

D) To mix different fluids

B) To discharge the pressurized fluid from the pump

A) To recirculate the fluid within the pump

C) To control the flow rate of the fluid

9 / 12

In a vane-type pump, what ensures that the vanes remain in contact with the casing during operation?

D) Magnetic attraction

A) Gravity

B) Springs or centrifugal force

C) Hydraulic pressure

10 / 12

How does a vane-type pump create suction to draw fluid into the pump?

A) By heating the fluid to reduce its viscosity

C) By increasing the pressure at the inlet port

D) By using an external compressor to force fluid into the pump

B) By creating a vacuum as the rotor and vanes rotate, increasing the volume in the pumping chamber

11 / 12

What is the function of the inlet port in a vane-type pump?

D) To exhaust air from the pump

A) To control the speed of the pump

C) To regulate the pressure of the fluid

B) To allow fluid to enter the pumping chamber

12 / 12

What happens to the fluid as the vanes rotate from the inlet to the outlet in a vane-type pump?

D) The fluid remains static until it reaches the outlet

C) The fluid is mixed with air to reduce its density

B) The fluid is pressurized as the volume in the pumping chamber decreases

A) The fluid is cooled to prevent overheating
