Marine Oily Handling Devices and Pollution Prevention Chapter 1 Lesson 3 Forced lubrication
1.3 Forced lubrication • In motorships the oil, after passing through main and motion bearings and oil-cooled pistons, etc., is either retained in the bedplate or flows by gravity to a sump tank. • In either case, the oil pumps, which may be self-priming, submerged centrifugal or rotary positive displacement, draw the oil through magnetic strainers and discharge to: filters - oil coolers - engine lubricating and/or cooling manifolds.
Lub oil can flow from the main bearing to the crank, connecting rod, crosshead, crosshead guide shoes and crosshead guides. sound
