Question 28Motor Plants - QMED

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 water buildup, which can lead to corrosion and damage to the air receiver and associated components. Allowing moisture to accumulate can compromise the system's reliability and safety, which is crucial for the proper functioning of the starting air system. The other options, while important maintenance procedures for other equipment, are not specifically required for starting air receivers. Frequent testing of relief valves (B) and monitoring temperature to prevent pressure fluctuations (C) are good practices, but they are not the primary routine maintenance requirement for starting air receivers. Cleaning to remove oil and foreign matter (D) is also important, but it is not the key maintenance procedure as specified in the question.
