Aux 1 Unit 7 Q1

Correct Answer: B) Compressed air systems have a lower efficiency in energy transfer, leading to higher energy costs.

Explanation: A disadvantage of compressed air systems is that they are less efficient in energy transfer compared to hydraulic systems. The energy loss in compressing air and maintaining air pressure can lead to higher energy costs and less efficient operation.

Correct Answer: B) To prevent corrosion, freezing, and damage to pneumatic components

Explanation: Removing moisture from the compressed air is crucial to prevent corrosion, freezing, and other damage to pneumatic components. Moisture can cause rust and corrosion in metal parts, lead to freezing in cold conditions, and reduce the overall efficiency and lifespan of the system.

Correct Answer: B) The moisture could cause corrosion, freezing, and malfunction of control components

Explanation: If moisture is not removed, it can cause significant problems such as corrosion and freezing, which can lead to malfunctions in the pneumatic control components, potentially resulting in system failure or decreased reliability.

Correct Answer: B) To prevent contamination of pneumatic components and ensure proper functioning of the system

Explanation: Limiting oil carryover is important to prevent contamination of pneumatic components, such as valves and actuators, which could lead to improper functioning, reduced efficiency, and potential damage to the system.

Correct Answer: A) Compressed air systems are generally cleaner and less likely to cause contamination if there is a leak.

Explanation: One significant advantage of compressed air systems is that they are cleaner than hydraulic systems. If a leak occurs, air does not cause contamination, unlike hydraulic fluid, which can lead to environmental or operational contamination.

Correct Answer: B) The oil can contaminate and damage sensitive control components, leading to malfunctions and reduced system performance

Explanation: Excessive oil carryover can lead to contamination of sensitive pneumatic components, causing malfunctions and reducing the overall performance and reliability of the system. It can also lead to blockages and increased maintenance requirements.
