Pid Control Of Main Engine Jacket Cooling System Youtube Basic principles of pid controllers. automatic controllers are used onboard ships for the adjustment of one or more parameters in a system. function of the controller is to maintain the parameter as per desired value (value set by the operator). the parameter could be jacket water temperature (for engine jacket water cooling system. 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 Water Cooling System Of Main Engine Marine Diesel Engine Jacket cooling water systemthe jacket cooling water system is used for cooling the cylinder liners, cylinder covers and exhaust valves of the main engine.lec. Use of pid control of main engine jacket cooling system. 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. These are centrifugal pumps which maintain the cooling water circulating pressure at about 4 bar. the temperature of the cooling water is controlled automatically by a 3 way valve. if no cooling is required (when the engine is stopped) then the valve allows water to circulate through the valve back to the pumps.
