Question 196Motor Plants - Assistant Engineer

The correct answer is A) Frequent draining of accumulated moisture. The routine maintenance procedure required for starting air receivers is the frequent draining of accumulated moisture. This is necessary to prevent the buildup of condensation, which can lead to corrosion and compromise the integrity of the air receiver. Allowing moisture to accumulate can also affect the performance and efficiency of the starting air system. The other options, while important for air receiver maintenance, are not specifically required as routine procedures. Option B (frequent testing of relief valves) and Option C (close watch on temperature to prevent fluctuations in pressure) are also important, but they are not the primary routine maintenance task for starting air receivers. Option D (frequent cleaning to remove oil and foreign matter) is also not the correct answer, as the primary concern is the removal of accumulated moisture.
