Question 43Steam Plants - QMED70% to pass
The adjustable spherically seated self-aligning bearing housings used in main turbines are provided with oil deflector rings. The function of these rings is to _______________.
AI Explanation
The correct answer is A) prevent the external leakage of oil out of the bearing housing.
The oil deflector rings in the adjustable spherically seated self-aligning bearing housings used in main turbines are designed to prevent the external leakage of oil from the bearing housing. This is an important function as it helps to maintain the proper oil level and lubrication within the bearing, while also containing the oil and preventing it from escaping the housing.
The other options are incorrect because: B) ensuring efficient lubrication is the role of the bearing itself, not the deflector rings; C) directing the flow of oil is a function of the bearing and oil channels, not the deflector rings; and D) preventing the leakage of main steam into the oil is not the purpose of the oil deflector rings.
