Aux 1 Unit 8 Q4

Correct Answer: A) Condensation inside the hydraulic reservoir

Explanation: Condensation inside the hydraulic reservoir is a common source of water contamination, especially in environments with fluctuating temperatures or high humidity, leading to water accumulation in the hydraulic fluid.

Correct Answer: B) Through leaks in seals, fittings, or breather caps exposed to wet environments

Explanation: Water ingress can occur through leaks in seals, fittings, or breather caps, especially if the system is exposed to wet environments, leading to water contamination in the hydraulic fluid.

Correct Answer: B) Corrosion of metal components within the system

Explanation: Water contamination can lead to corrosion of metal components within the hydraulic system, which can cause significant damage, reduce the lifespan of the equipment, and lead to costly repairs.

Correct Answer: B) Water contamination decreases the fluid's ability to lubricate, leading to increased wear on components.

Explanation: Water contamination reduces the hydraulic fluid's ability to lubricate components effectively, leading to increased friction, wear, and potential failure of moving parts within the system.

Correct Answer: B) Water contamination can cause the formation of emulsions, reducing the system's efficiency.

Explanation: Water contamination can lead to the formation of emulsions in the hydraulic fluid, which can reduce the system's efficiency by affecting the fluid's flow characteristics and leading to inconsistent performance.

Correct Answer: B) By causing cavitation and reduced fluid flow

Explanation: Water contamination can cause cavitation, where vapor bubbles form and collapse within the fluid, leading to reduced fluid flow, noise, vibration, and potential damage to system components.

Correct Answer: B) Gradual deterioration of system components, leading to premature failure and costly repairs

Explanation: If water contamination is left unchecked, it can lead to gradual deterioration of system components due to corrosion, wear, and other related issues, eventually causing premature failure and necessitating costly repairs.

Correct Answer: B) Immediately shut down the system to prevent further damage

Explanation: If water contamination is suspected, the system should be shut down immediately to prevent further damage to components and to allow for proper inspection and remediation.

Correct Answer: B) Take a sample of the hydraulic fluid and perform a visual inspection or laboratory analysis to detect water content

Explanation: A sample of the hydraulic fluid should be taken and either visually inspected for signs of water (such as cloudiness or separation) or sent for laboratory analysis to confirm the presence and concentration of water contamination.

Correct Answer: A) Replace or clean the hydraulic fluid and address the source of water ingress

Explanation: Once water contamination is confirmed, the contaminated hydraulic fluid should be replaced or cleaned (using a filtration system), and the source of water ingress (such as leaks or poor sealing) should be identified and corrected to prevent future contamination.
