SISTEM MAZANJA GLAVNEGA MOTORJA

Kleva, Luka (author), Perkovič, Marko (mentor)

Pravilno in varno delovanje ladijskega motorja pomeni varno plutje vseh ladij, to pa je zelo tesno povezano z mazanjem motorja. Strojno službo na ladji sestavlja več članov posadke, ki so ustrezno usposobljeni za nadzorovanje stanja ter upravljanja s sistemi in podsistemi. Strojnik, ki opravlja stražo avtomatizacije in zaščite motorja, se mora zelo dobro spoznati na pogon ter redno beležiti parametre in vsako spremembo stanja, ki jo mora razumeti, da lahko, če je to potrebno, pravočasno ustrezno ukrepa. Osnovna naloga sistema mazanja je, da se ta "bori" proti trenju. To funkcijo pa opravlja mazalno olje, ki zaščiti motorne dele pred poškodbami. Motorno olje je življenjska tekočina motorja in se analizira v laboratorijih. Na podlagi te analize pa se lahko določi, ali je prišlo do prekomerne obrabe ali okvare na motorju. Če se odkrije dovolj zgodaj, se lahko tudi zelo enostavno sanira, torej, ne pride do večjih poškodb in seveda velikih stroškov. V zadnjem delu naloge sem uporabil strojni simulator, ki se je zelo približal realnemu stanju na veliki ladji, opravil pa sem tudi nekaj simulacij okvar in sprememb stanja na sistemu mazanja.

• Title: SHIP'S MAIN ENGINE LUBRICATION SYSTEM

Abstract

The proper and safe operation of a ship's engine means the safe navigation of all ships, and this is very closely connected with engine lubrication. The engine room service consists of several engineers who monitor the condition and manage the system and subsystems. The engineer on watch, in addition to the overall automation and engine protection, must know the propulsion system very well and regularly record and understand the parameters and any change in condition so that he can take appropriate action in time. The lubrication system has the basic task of fighting friction and this function is performed by lubricating oil which protects the engine parts from damage. Engine oil is the lifeblood of the engine, which is also analyzed in laboratories and diagnoses what is good or bad and helps to prevent a problem like excessive wear or damage to the engine, which is hidden somewhere and is a disease and if detected early is also very easy to repair without much damage and cost. In the last part of the paper, I have used an engine simulator which is very close to the real situation on a large VLCC ship and performed some simulations of failures and condition changes of the lubrication system.
