Excellent video. I'm an electrical engineer, studying to be an ETO. This is a great explanation for someone with a limited mechanical background. Very easy to grasp.
i find the best channel, for junior seaman's! T.y. guy's. Очень познавательно для начинающих работать в микс экипажах! подтянуть технический язык то что надо
That depends on the pressure in the pipes. The higher the pressure the the higher boiling point. 1. After Liner can for some engines be up to 130degC 2. After Cylinder Head can for som engines be up to 85degC 3. Depends on the engine load - if the load is high the temeprature is low. Hope it helped.
Thanks very good explanation...i would like to ask you a question about the pumps..you said that when the engine is stoped we close jacket pump and start fw circ pump ...this procedure is in all merchant ships ? I'm gonna embark on a bulk carrier and i would like to know. There are always circ pumps for that reason or in some ships we use only jacket pumps ?? I will appreciate your answer thanks !!!
All foreign going ships are fitted with small circulation pump. This is done to reduce the power consumption (as jacket water will consume more power) and hence the fuel consumption of the auxiliary engine.
@@marineinsight In addition to that, hence main engine is stop no need much HT pressure for cooling the cylinder liner,head, exhaust valve etc...only to provide heating to prevent thermal shock and prevent jacket cooling water leakage.
Thank you for the suggestion. We do have an ebook on different marine engine components, explaining its function and maintenance. learn.marineinsight.com/eBooks/e-2-stroke-marine-engine-components/
There are different companies who provide chemcals under their brand name. However, following composition remains the same - Nitrite, carboxylates, Nitrite boarte, nitrite polymers
Better show in detail a lng reliquifaction plant: what is the main cooling medium, any compander, comressor, electric motor room. Next gas fuel system)))
What happens to the heated "sea water" after it leaves the "Sea Water Cooler"? The heated sea water is expelled back into the sea. As wiki says: "At any given moment there are 50,000 merchant ships crossing the worlds oceans. The heat from the cooling systems of these ships on the oceans of the world is what is really causing climate change, heat wave and drought.
Thanks for the explanation, this lesson was quite usefull for me, cuz for now i'm a cadet. Have you a video about HVAC system and sewage treatment plant?
Deaerator is used to remove trapped air bubbles from the circulating water in order to avoid pressure fluctuations (which in turn could cause damage to the pipe lines). So no, it is not advisable to NOT use Deaerator.
Liner is the cylinder which forms the part of combustion chamber in which piston moves. Jacket is a part of entablature, covering the liner to provide cooling water passage 👍🏻
