Jacket Water Cooling System Of Main Engine Marine Diesel Engine The high temperature (ht) cooling water system, also known as the jacket cooling water (jcw) system, is used for cooling the cylinder liners, cylinder covers and exhaust gas valves of the main engine and heating of the fuel oil drain pipes, see fig. 12.01.01. the jacket water pump draws water from the jacket water cooler outlet,. 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 bars. the.
Jacket Cooling Water System Youtube 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. 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. High temperature cooling water system. the high temperature (ht) cooling water system, also known as the jacket cooling water (jcw) system, is used for cooling the cylinder unit components of the main engine and heating of the fuel oil drain pipes. the design of the jacket cooling water piping varies, depending on the engine type and fuel sul. 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.
