Part of the heat generated during combustion in diesel machines It is transported to the cylinder wall and raises its temperature. Operations of diesel machines During the combustion chambers, a very high temperature occurs around 1400#8211 around 1900 degrees. As a result, during the business cycle and under full load, gases in a cylinder The average temperature varies between 500#8211; The temperature of the gases at this temperature is cylinder Since it is absorbed by its wall, the machine's operation is safe enough Impossible In this case, the oil film on the cylinder wall will burn quickly. The clauses (openings) are eliminated and these sections are quickly worn piston The head and valve discs are tackled and burned. Heat cylinder shirts consisting of friction of pistons during the operation is transferred to cooling water by. Meanwhile, the heat in the beds without friction It is transported by the lubrication oil out of the bed, to the crankcase and from there to the cooler or tower. It is then transferred from there to sea water. Thus, with the help of algebra cooling water A low temperature is provided in the employee parts and this temperature is maintained. The heat formed by the burning of fuel in the combustion chambers of the cylinders of the diesel machines The amount varies between approximately 1250 kcal/bhp/hp. In the machines that are cooled with water, 28-33 % of this temperature is cooling water of its reputation, with air In cooling machines, 25 %shows that it is transported out of the machine with air. If If a process is not done to eliminate this heat, the cylinder metal temperature burns It will approach the temperature they carry while leaving the cylinders. The damage to the machines is too important to be compared to anything else. As a result, the need to cool the ship's main and auxiliary machines it comes out. With this course, with the maintenance and repair of the cooling system of ship diesel engines You will gain the necessary information and skills.
