Jacket Water Cooling System Of Main Engine Marine Diesel Engine The main purpose of this section is to give all operation personnel a basic understanding of :• the engine most essential functions.• how the jacket cooling. J.w cooler. cooling can be done by dedicated coolers which cools the hot jacket water from the main engine. cooling medium is fresh water or sea water, in new ships central cooling systems are used, where fresh water as a cooling medium. circulating pump: there are two jacket water circulating pumps used onboard with a discharge pressure of 3 4.
Jacket Cooling Water System Youtube Jacket water cooling of main engine on ships has to be carried out in order to lower the temperature ponents of the this jw cooling system are cooler, two. Fig. 12.01.03 shows the jacket cooling water piping valid for me lgi engines, which are not mentioned in item 2 and section ‘jacket cooling water 2’, oper ating on fuel with a sulphur content >0.5%. numbers 1) to 5) on fig. 12.01.03 refer to notes listed after the figure. fig. 12.01.03: jacket cooling water system for me lgi engines which. The ht cooling water system is circulated by electrical cooling water pumps, one in service and one on standby. during standby, the dg is kept warm by the circulating system from the dg in service. when me is stopped, it is kept warm by ht cooling water from dg. if this is insufficient, the water may be heated by a steam heated fw heater. This makes the cooling water system design more flexible. a cooling water temperature of approximately 80°c (176°f) and cooling water pressure of 3 bar (44 psi) is standard for most engines operating under load. cooling water is sometimes referred to as ' jacket water ' due to the 'jacket' of water surrounding the combustion space.

A water cooling system for a slow speed diesel engine is shown in figure above. it is divided into two separate systems: one for cooling the cylinder jackets, cylinder heads and turbo blowers; the other for piston cooling. the cylinder jacket cooling water after leaving the engine passes to a sea water. The main engine is cooled by two separate but linked systems: an open system (sea to sea) in which water is taken from and returned to the sea (seawater cooling), and a closed system where freshwater is circulated around an engine casing (freshwater cooling). freshwater is used to cool machinery directly, whereas seawater is used to cool.
