Patent attributes
A lubricating oil system includes a reservoir configured to enclose a lubricant oil; a filter assembly that includes at least one filter and is positioned in the reservoir to separate the reservoir into a first oil tank and a second oil tank, where the first oil tank fluidly is coupled to the rotating machine through an oil return line; a system pump fluidly coupled to the reservoir and configured to circulate the lubricant oil from the second oil tank to the rotating machine through an oil supply line; and a circulating pump assembly. The circulating pump assembly includes a conduit that fluidly couples the first oil tank to the second oil tank external to the reservoir, a circulating pump coupled within the conduit and including a suction coupled to the first oil tank and a discharge coupled to the second oil tank, and a media filter coupled within the conduit and between the first oil tank and the second oil tank.
