Analysis Of Increasing Lubricating Oil Temperature In Ship Diesel Generators

Abstract

Abstract Auxiliary aircraft is a vital part of a ship that is needed as a power plant or generator. In order to avoid more heat, lubricating oil is needed in the form of a chemical substance, in the form of a liquid given between two moving objects to reduce friction, as a protective layer separating the two surfaces in contact. This is due to the operation of the diesel generator which occurs continuously and can cause friction and erosion of the moving parts. So that friction causes changes in material structure which over time can cause heat. However, this condition makes the lubricating oil temperature increase every hour. This qualitative research uses Primary and secondary data collection methods, with observation (field survey), interviews and library research. Based on the results of the analysis, the cause of the increase in lubricating oil temperature is due to the condition of the electromotor of the seawater cooling pump through the bypass faucet not according to the desired pressure, pump bearings have wear and pump gears, then the heat absorption of the L.O Cooler shelf is not optimal due to blockages in the capillary pipes. That the increase in the temperature of the diesel generator lubricating oil above 700 C and the pressure of 2 kg/cm2 during the machinist’s duty hours 00.00-04.00 LT is caused by the diesel generator auxiliary motor having an ineffective Lo Cooler heat absorption capacity, sea water cooling pressure that is less than normal and the presence of pipe connections that leak cooling pipes
