Oilers/Plant Tenders (HHC) Civil Service Practice Exam

Which of the following statements is true regarding force-feed lubricators?

1. They are manually operated

2. They do not provide positive oil pressure

3. They automatically supply oil

4. They are only used in small machinery

The correct answer is: They automatically supply oil

Force-feed lubricators are designed to automatically supply oil under pressure to various components of machinery, ensuring that the lubrication system operates efficiently. This feature is crucial because it allows for consistent and adequate lubrication, which is essential for maintaining optimal performance and preventing wear and tear on moving parts. Automatic oil supply minimizes the risk of human error associated with manual lubrication processes, ensuring that machinery receives the correct amount of lubrication at all times, even in automated or continuous operation environments. This functionality is particularly beneficial in larger machinery systems where manual lubrication might be impractical due to size or operational demands. The other statements do not accurately represent the characteristics of force-feed lubricators. For instance, stating they do not provide positive oil pressure contradicts their primary function, and the notion that they are only used in small machinery is misleading, as they are often implemented in larger industrial systems to enhance reliability and efficiency.
