What is the primary function of an oil separator?

The primary function of an oil separator is to clean oil of dirt, sludge, and other contaminants. This process is essential in maintaining the integrity and efficiency of hydraulic systems or machinery where oil is used as a lubricant or hydraulic fluid. By removing contaminants, the oil separator ensures that the oil remains effective in its role, preventing wear and tear on components and promoting optimal performance.

Oil separators typically employ various mechanisms, such as gravity separation, filtration, and coalescing, to achieve this cleaning process. They can help extend the life of the oil and the machinery, reduce maintenance costs, and support environmentally safe practices by minimizing waste generation.

The other options, while related to oil management, do not accurately define the core function of an oil separator. Filtering oil and storing contaminants, heating oil, or blending different types of oil represent different processes involved in oil handling, but they do not capture the primary purpose of an oil separator effectively.
