Abstract:
A rotor for a self-powered centrifugal separator for separating particulate contaminants from a liquid supplied to the separator at elevated pressure, said rotor comprising a canister arranged to spin about a rotation axis, having an outer, peripheral wall including a peripheral side wall displaced from the rotation axis and at least one end wall, an internal partition wall extending radially inwardly from the peripheral wall dividing the canister into a separation chamber and an outflow chamber and defining at its radially inner periphery a transfer aperture between the separation and outflow chambers, said separation chamber including an inlet aperture to admit contaminated liquid, and the outflow chamber having at least one nozzle spaced radially from said rotation axis to eject liquid from the canister, and a rotor separation funnel arrangement within the separation chamber, the rotor separation funnel arrangement supported coaxially within the separation chamber and having an inclined surface generated about a longitudinal axis common to the rotation axis, and sloping downwardly towards the rotation axis from an upper end concentric with the separation chamber to a lower end apertured so as to direct liquid by way of said inclined surface to the transfer aperture.
