Oilers/Plant Tenders (HHC) Civil Service Practice Exam

How is interval or cylinder lubrication of vertical marine steam engines typically achieved?

1. Using a manual grease gun

2. With a flow control valve

3. A mechanical force feed lubricator

4. By direct oil injection systems

The correct answer is: A mechanical force feed lubricator

Cylinder lubrication in vertical marine steam engines is largely achieved through the use of a mechanical force feed lubricator. This system ensures a consistent and controlled delivery of lubricant directly to the operating components of the engine, helping to reduce friction and wear over time. The mechanical force feed lubricator operates by utilizing a mechanism that pushes the lubricant through a network of pipes or tubes to the designated areas in need of lubrication, such as the cylinders. This is crucial for maintaining efficient operation and preventing damage caused by inadequate lubrication. Selecting a mechanical force feed lubricator as the method of lubrication is particularly effective, as it provides a reliable means of ensuring that the engine components receive the necessary amount of oil at regular intervals, thus maintaining optimal performance and longevity of the engine.
