Oilers/Plant Tenders (HHC) Civil Service Practice Exam

What role does wool waste serve when placed in oil cups?

1. To reduce the viscosity of oil

2. To filter impurities from the oil

3. To act as a feed for increased oiling

4. To decrease the frequency of oiling

The correct answer is: To act as a feed for increased oiling

Wool waste serves a specific function when placed in oil cups, and that role is to act as a feed for increased oiling. When wool waste is added to oil cups, it helps retain oil within its fibers and slowly releases it over time. This property ensures a consistent supply of lubrication, which is crucial in machinery operations to prevent wear and tear on moving parts. By providing a gradual and sustained release of oil, wool waste enhances the lubrication process and helps maintain optimal functioning of equipment. The other choices do not accurately reflect the role of wool waste in this context. For instance, while filtering impurities may be important in some lubrication systems, wool waste is not primarily used for this purpose. It is also not designed to reduce viscosity or decrease the frequency of oiling; rather, it ensures that there is an adequate and continuous supply of oil to the machinery. Thus, the correct function of wool waste is indeed to serve as a feed for increased oiling.
