Aux 1 Unit 6 Q6

1 / 10

What could happen if an air receiver does not have a fusible plug and it overheats?

C) The receiver would operate more efficiently

D) The air receiver would cool down automatically

A) The receiver would automatically reduce pressure

B) The air receiver could overheat without any relief, leading to an explosion

2 / 10

In what situation would the fusible plug on an air receiver typically activate?

B) When the internal temperature of the air receiver exceeds the fusible plug's melting point

C) When there is a minor pressure fluctuationc

D) When the air receiver is overfilled with compressed air

A) When the air receiver is underfilled

3 / 10

What would be the consequence of not having a fusible plug on an air compressor that overheats?

A) The compressor would automatically shut down safely

D) The compressor would start to cool down automatically

C) The compressor's efficiency would increase

B) The compressor could overheat without relief, leading to potential damage or explosion

4 / 10

How does the fusible plug enhance the safety of an air compressor?

D) By automatically regulating the airflow through the compressor

B) By providing a safety mechanism that prevents dangerous pressure build-up due to overheating

C) By reducing the operating temperature of the compressor

A) By increasing the pressure capacity of the compressor

5 / 10

Why is the specific melting point of the fusible plug important for its function on an air receiver?

A) It should melt at any temperature to ensure constant safety

D) It should never melt to maintain pressure inside the receiver

B) It must melt only under normal operating conditions

C) It should be set slightly above the maximum operating temperature to activate only under emergency conditions

6 / 10

Why is the temperature at which a fusible plug melts critical for an air compressor?

A) It must melt at a temperature lower than the normal operating range to ensure it functions frequently

D) It must melt at the lowest possible temperature to prevent any operational risks

C) It should never melt under any circumstances

B) It must melt at a temperature just above the normal operating range to provide a safeguard against abnormal conditions

7 / 10

In what scenario would the fusible plug on an air compressor typically operate?

B) When the temperature of the compressed air or compressor components becomes dangerously high

D) When there is an excess of moisture in the compressed air

C) When the compressor is running at maximum efficiency

A) When the air pressure is too low

8 / 10

What is the primary reason for fitting a fusible plug on an air receiver?

C) To reduce the noise generated by the air receiver

A) To increase the air storage capacity

D) To maintain a consistent air pressure

B) To release pressure if the temperature inside the air receiver becomes dangerously high, preventing explosion

9 / 10

How does a fusible plug protect the structural integrity of an air receiver?

D) By filtering the air inside the receiver

C) By automatically reducing the air pressure inside the receiver

B) By releasing pressure in the event of overheating, preventing the receiver from bursting

A) By increasing the strength of the air receiver walls

10 / 10

Why might a fusible plug be fitted on an air compressor?

B) To release pressure automatically if the compressor overheats, preventing potential fire or explosion

D) To improve the efficiency of the air compression process

A) To increase the air pressure during operation

C) To reduce the noise level of the compressor
