Aux 1 Unit 7 Q3

1 / 8

What is one of the main purposes of an accumulator in a pneumatic control system?

C) To filter contaminants from the compressed air

D) To increase the operating temperature of the system

A) To cool the compressed air before it enters the system

B) To store compressed air for future use and maintain pressure during peak demand

2 / 8

Why is it essential to maintain the proper operation of an accumulator in a pneumatic control system?

D) To increase the humidity of the compressed air

B) To ensure consistent air supply, absorb pressure shocks, and protect the system from fluctuations that could lead to damage or reduced performance

A) To prevent the system from becoming too cold

C) To reduce the amount of air required by the system

3 / 8

Why is the shock-absorbing function of an accumulator critical in pneumatic control systems?

D) It increases the speed of air flow in the system

A) It increases the pressure in the system

B) It helps to maintain consistent pressure and prevent damage from pressure spikes, ensuring smooth operation

C) It reduces the noise generated by the pneumatic system

4 / 8

Why is it important for an accumulator to store compressed air and maintain pressure during peak demand in a pneumatic control system?

D) To reduce the energy consumption of the system by keeping the compressor off

A) To allow the compressor to run continuously without shutting down

C) To increase the temperature of the compressed air during peak times

B) To ensure that the pneumatic system has sufficient air supply during high demand periods without requiring the compressor to operate constantly at full capacity

5 / 8

What could happen in a pneumatic system without an accumulator to maintain pressure during peak demand?

A) The system will produce cleaner air

C) The system may experience pressure drops and reduced performance during high demand, leading to inefficient operation

D) The system will require less maintenance

B) The compressor will operate more efficiently

6 / 8

How does the use of an accumulator improve the overall efficiency of a pneumatic control system?

C) By filtering out contaminants from the air

A) By storing excess air and releasing it when needed, reducing the load on the compressor and energy consumption

B) By increasing the air pressure continuously

D) By cooling the air before it is used

7 / 8

What potential problems might occur in a pneumatic control system without an accumulator acting as a shock absorber?

C) The system will require more lubrication

B) Pressure fluctuations could cause vibrations, noise, and damage to pneumatic components, leading to frequent maintenance issues

D) The air quality will improve

A) The system may operate at higher temperatures

8 / 8

What is the second main purpose of an accumulator in a pneumatic control system?

B) To act as a shock absorber, reducing pressure fluctuations and ensuring smooth operation

C) To increase the efficiency of air compression

D) To decrease the humidity of the compressed air

A) To reduce noise levels in the system
