ABSTRACT:
A centrifugal filter separator system operable to separate from oil under pressure, contaminants and water. The centrifuged water port of the centrifugal filter separator of the system is coupled to a differential pressure responsive, sensor control, which automatically senses the presence of a layer of centrifuged water against the internal surface of the rotating drum of the centrifugal separator. The sensor control is coupled to a flow control circuit which in conjunction with the differential pressure sensor control causes automatic removal of an existing layer of centrifuged water from the rotating drum via the water exit port of the separator. When there is no adequate depth layer of centrifuged water on the inner surface of the rotating drum, the sensor control deactivates the water removal circuit, while the flow control circuit maintains a minimum generally constant flow of liquid from the water port of the separator for priming purposes. The flow control circuit is coupled to a pressurized gravity type separator in the system from which separated oil is returned back to the centrifugal filter separator. The gravity separator includes an inverse relief valve circuit for replenishing water evacuated from the gravity separator, with oil from the pressure port of the system pump.
