Centrifugal oil filter working principle

The working principle of a centrifugal oil filter is based on the centrifugal force generated by a rotating element. Here’s how it generally works:

1. Inlet: Contaminated oil is fed into the filter through an inlet.

2. Centrifugal Action: Inside the filter, a rotating element (such as a rotor or bowl) spins at high speeds. This rotation creates a strong centrifugal force that pushes heavier particles (like dirt, water, and other contaminants) outward against the inner wall of the filter.

3. Separation: As the oil flows through the rotating element, the centrifugal force separates the contaminants from the clean oil. The contaminants are flung against the wall, where they accumulate, while the cleaner oil moves toward the center.

4. Outlet: The purified oil is then collected and directed out of the filter through an outlet, while the accumulated contaminants are either collected at the bottom or can be drained out periodically.

5. Maintenance: Depending on the design, the accumulated contaminants may need to be removed manually or can be automatically discharged.

Centrifugal oil filters are efficient at removing particulate matter and can handle high flow rates, making them suitable for various applications, including hydraulic systems and engine lubrication.
