Question 377Steam Plants - 1st Asst/Chief70% to pass
When a sudden increase in pressure occurs in a forced lubrication system, you should check for a _______________.
AI Explanation
The correct answer is C) loss of oil flow across one of the bearings.
When there is a sudden increase in pressure in a forced lubrication system, it typically indicates a blockage or restriction in the oil flow path, often caused by a loss of oil flow across a bearing. This increased pressure is the system's response to maintain the necessary oil flow to critical components, such as bearings, despite the restriction.
The other options are incorrect because: A) a high lube oil sump level would not cause a sudden pressure increase, B) a clogged pump suction would prevent the system from building pressure, and D) a ruptured tube in the lube oil cooler would more likely result in a pressure drop rather than an increase.
