Date: August 28, 2023 By: Daniel G. Teleoaca – Marine Chief Engineer Oil purifier is a device that removes water, gas and solid impurities from oil, such as lubricating oil and fuel oil, to improve its quality and extend its service life. Oil purifier is widely used in industrial and marine applications, where oil contamination…
Marine oil purifier bowl is a vital component of a centrifugal purifier that is used to separate water and solid impurities from fuel oil or lube oil on board ships. The purifier bowl is a kind of container that rotates at a high speed and creates a centrifugal force that pushes the heavier water and…
In marine oil purifiers, the vertical shaft assembly plays a crucial role in ensuring efficient oil purification and engine performance. This essential component is responsible for driving the separation process, which removes impurities and water from the oil. However, like any mechanical part, the vertical shaft assembly is prone to failure and malfunction. In this…
During operation of engines (especially trunk type engines) the lubricating oil will gradually be contaminated by small particles originating from the combustion and, in particular engines operated on heavy fuels which will normally increase the contamination due to the increased content of carbon residues and other contaminants (about four stroke lubricating system you can read…
This is another on-demand post and its purpose is to explain the 4-stroke lubrication system from operational point of view. All running gear of the 4-stroke engine is forced lubricated by an engine-driven gear type pump which takes the oil from the engine sump tank. The same oil from engine sump tank is also provided…
Purifiers clean fuels and lubricants as well as processing bilge water and sludge, but onboard vessels they are mainly part of fuel and oil treatment system. Purifiers are usually under a junior engineer responsibility and, sometimes they proves to be real nightmares for some of them, mainly because of lack of knowledge regarding operating principle,…
