ANORDNING TIL CYLINDERSMØRING TIL EN STOR, LANGSOMT KØRENDE, TOTAKTSDIESELMOTOR OG FREMGANGSMÅDE TIL ANVENDELSE AF CYLINDERSMØRINGSSYSTEMET

摘要

A cylinder lubrication device (1) for a large slow running two-stroke diesel multi-cylinder engine having in each cylinder (110) a reciprocating piston (120) with piston rings (121) that slide on the inner surface of the cylinder liners (111) whereby the cylinder lubrication device (1) provides the inner surface of the cylinder liners with a precisely dosed quantity of cylinder lubrication oil for each reciprocation of the piston (120) via a plurality of injection points that are distributed at equal level around the circumference of a cylinder, the cylinder lubrication device (1) comprises a plurality of piston pumps having a dosing plunger (30) slidably movable in the dosing cylinder (20) between a start position (S) and an end position (E), a common drive (31) including a linear actuator (41,46) for driving all of the dosing plungers (30) simultaneously, the dosing plungers (30) having a predetermined full stroke between the start position (S) and the end position (E), wherein the diameter of the dosing cylinders is such that the precisely dosed quantity is delivered by moving the dosing plungers (30) over a fraction of the maximum stroke so that the dosing plungers (30) can be moved in part strokes a plurality of times in the direction from the start position towards the end position before the dosing plungers need to be returned to the start position.
