Aux 1 Unit 4 Q6

1 / 10

What is the role of the air release valve in a centrifugal pump priming system?

D) To maintain a constant flow rate

B) To allow trapped air to escape during the priming process

C) To add air to the suction line for better priming

A) To increase the pressure in the discharge line

2 / 10

What happens once the centrifugal pump is fully primed in a system with a priming pump driven from the centrifugal pump?

B) The priming pump automatically disengages or reduces operation

C) The centrifugal pump shuts down

A) The priming pump continues to operate at full capacity

D) The priming pump increases the flow rate

3 / 10

Which of the following components might be included in a centrifugal pump system to automatically control the operation of the priming pump?

A) Pressure switch

B) Manual throttle

D) Temperature sensor

C) Flow meter

4 / 10

How is the priming pump typically driven in a system where it is coupled with a centrifugal pump?

D) By hydraulic pressure

A) By a separate motor

B) By the main drive shaft of the centrifugal pump

C) By manual operation

5 / 10

Why is it important for the priming pump to be sized correctly in a centrifugal pump system?

A) To prevent the centrifugal pump from operating at too high a flow rate

B) To ensure that the priming process is completed quickly and efficiently

C) To reduce the noise generated by the system

D) To increase the pressure in the discharge line

6 / 10

In a centrifugal pump system with a priming pump, what is the purpose of the vacuum created by the priming pump?

B) To draw liquid into the pump casing and suction line

A) To reduce the energy consumption of the centrifugal pump

D) To cool the centrifugal pump during operation

C) To increase the discharge pressure of the centrifugal pump

7 / 10

What is the primary purpose of a priming pump in a centrifugal pump system?

B) To remove air from the suction line and fill the pump with liquid

C) To cool the centrifugal pump during operation

D) To regulate the discharge pressure

A) To increase the flow rate of the centrifugal pump

8 / 10

What type of valve is commonly used in the suction line of a centrifugal pump system to assist with priming?

C) Relief valve

B) Gate valve

A) Check valve

D) Butterfly valve

9 / 10

What could happen if a centrifugal pump is operated without being properly primed?

C) The pump will increase its efficiency

A) The pump will operate normally

B) The pump may cavitate and suffer damage

D) The pump will automatically shut down

10 / 10

How does a float valve function in a centrifugal pump priming system?

D) It regulates the temperature of the pump

C) It increases the flow rate through the centrifugal pump

A) It opens the discharge valve when the pump is primed

B) It disengages the priming pump when the liquid level is sufficient
