Abstract
A separator for removing contaminants from a circulating liquid, preferably a contaminated oil, by use of centrifugal motion wherein a cylindrical chamber is mounted about a spindle serving as an axis of rotation. In-flowing contaminated liquid to be treated enters the cylindrical chamber and the base of said chamber and is directed onto distribution disk wherein it impacts a plurality of drive surfaces that impart a first source of rotational motion to said chamber. The in-flowing oil to be treated is directed against the inner wall of the cylindrical chamber, thus causing contaminant to adhere to the inner wall. As the thickness of contaminant increases on the inner wall of the chamber, the rotational speed of the chamber is reduced until it reaches a predetermined threshold speed causing a sensor to activate a signal indicating that the separator needs to be cleaned of contaminant. There is also provided a porous material at the exit where treated liquid exits and which, after a period of time, will become blocked and thus also acting to slow the rotational speed of the chamber.
