Aux 1 Unit 7 Q5

Correct Answer: B) It can cause contamination of the system, leading to seal degradation, component sticking, and malfunctions.

Explanation: Oil mist can contaminate the pneumatic control system, leading to the degradation of seals, causing components to stick or malfunction, and reducing the overall reliability and lifespan of the system.

Correct Answer: B) Moisture (water vapor)

Explanation: Moisture (water vapor) is a common contaminant in compressed air systems. It can cause various issues, such as corrosion, freezing, and improper operation of pneumatic components.

Correct Answer: B) It can cause corrosion, rust, and freezing in components, leading to damage and malfunction.

Explanation: Moisture in a pneumatic system can cause corrosion and rust in metal components, leading to damage, reduced reliability, and potential system failure. In cold conditions, moisture can freeze and block air passages, further disrupting system operation.

Correct Answer: B) To prevent damage to components, ensure smooth operation, and maintain system efficiency.

Explanation: Filtering out contaminants such as moisture, dust, and oil mist is crucial to prevent damage to pneumatic components, ensure smooth operation, and maintain the overall efficiency and reliability of the system. Contaminants can cause corrosion, wear, and malfunctions, leading to costly repairs and downtime.

Correct Answer: A) Oil mist

Explanation: Oil mist, which can originate from the compressor, is a contaminant that can degrade seals, cause sticking or malfunction of pneumatic components, and reduce the overall performance and longevity of the system.

Correct Answer: A) Dust and dirt particles

Explanation: Dust and dirt particles are common contaminants in compressed air systems. They can clog filters, damage sensitive components, and reduce the efficiency and reliability of the pneumatic system.

Correct Answer: B) They can clog filters, damage sensitive components, and reduce system efficiency.

Explanation: Dust and dirt particles can clog filters, cause abrasion and wear on sensitive components, and reduce the overall efficiency and reliability of the pneumatic control system. Keeping the air supply clean is essential to maintain optimal performance.
