OIL FEED METHOD TO AN OILLSEAL DEVICE OF A STERN TUBE

摘要

PURPOSE:To prevent oil shortage in the seal-ring grip section and obtain a sealing effect over an extended period of time by driving a pump using the revolution of a propeller shaft so that the pump feeds a predetermined amount of the oil into the cavity on the bow side of a seal device positioned at the stern and keeps the cavity always filled up with the oil.
