Aux 1 Unit 6 Q6

1 / 10

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

D) To improve the efficiency of the air compression process

A) To increase the air pressure during operation

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

C) To reduce the noise level of the compressor

2 / 10

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

D) By filtering the air 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

C) By automatically reducing the air pressure inside the receiver

3 / 10

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

A) The receiver would automatically reduce pressure

D) The air receiver would cool down automatically

C) The receiver would operate more efficiently

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

4 / 10

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

C) The compressor's efficiency would increase

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

D) The compressor would start to cool down automatically

A) The compressor would automatically shut down safely

5 / 10

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

A) To increase the air storage capacity

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

C) To reduce the noise generated by the air receiver

D) To maintain a consistent air pressure

6 / 10

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

C) It should never melt under any circumstances

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

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

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

7 / 10

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

C) When the compressor is running at maximum efficiency

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

A) When the air pressure is too low

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

8 / 10

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

C) By reducing the operating temperature of the compressor

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

A) By increasing the pressure capacity of the compressor

D) By automatically regulating the airflow through the compressor

9 / 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

D) When the air receiver is overfilled with compressed air

C) When there is a minor pressure fluctuationc

A) When the air receiver is underfilled

10 / 10

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

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

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