Abstract:
A circulation lubrication system comprising:a lubricating oil tank; pressure pipe lines configured to supply oil to part to be lubricated; return pipe lines configured to return the oil from the parts to be lubricated to the oil tank; and a mechanism configured to pump oil into the pressure pipe lines and maintain a desired state of lubrication, wherein the lubricating oil tank has rotationally symmetric structure, and a return duct positioned at the center axis of the rotationally symmetric structure and further configured to extend below the surface of the oil contained in the lubricating oil tank, wherein a return flow through the return duct passes through a dividing element to a mechanism configured to separate impurities from the oil, the mechanism configured to separate impurities from the oil including a structure of partition walls positioned one upon another and having a mutual spacing, wherein the partition walls are attached to air collecting ducts that lead to an air space located in an upper portion of the lubricating oil tank, and to water collecting ducts that extend to a bottom portion of the lubricating oil tank; wherein a suction duct of the pressure pipe lines is positioned at the center axis of the rotationally symmetric structure of said lubricating oil tank.
