1 / 8

How does a fusible plug enhance the safety of an air receiver?

D) It regulates the flow of air into the receiver

C) It filters impurities from the compressed air

A) It adjusts the pressure inside the receiver automatically

B) It melts at a specific temperature, releasing air to prevent overheating and overpressure

2 / 8

B) Pressure gauge

C) Water pump

A) Fuel injector

D) Thermocouple

3 / 8

What triggers the operation of a fusible plug on an air receiver?

B) Excessive internal temperature that melts the plug, releasing pressure

A) High-pressure conditions

C) Low pressure in the air receiver

D) Operator intervention

4 / 8

How does a pressure relief valve on an air receiver operate?

C) It manually releases air when the operator pulls a lever

D) It filters out contaminants from the air

A) It opens automatically to release excess pressure if the pressure inside the receiver exceeds the set safety limit

B) It opens and closes based on the temperature inside the receiver

5 / 8

Which fitting on an air receiver is used to remove accumulated water (condensate) from the bottom of the receiver?

D) Air filter

C) Relief valve

A) Sight glass

B) Drain valve

6 / 8

Which fitting on an air receiver indicates the amount of pressure inside the receiver at any given time?

A) Pressure gauge

C) Drain valve

D) Temperature gauge

B) Relief valve

7 / 8

Which safety device is responsible for preventing overpressure in an air receiver by automatically venting air when pressure exceeds a preset limit?

C) Drain valve

A) Fusible plug

D) Non-return valve

B) Pressure relief valve

8 / 8

What is the purpose of a safety valve fitted on an air receiver?

B) To release excess pressure automatically if it exceeds safe limits

C) To measure the amount of air stored in the receiver

D) To control the flow rate of air into the receiver

A) To regulate the temperature inside the receiver
