How to carry out daily maintenance of ship engine accessories cylinder? After installing the new ring or replacing the cylinder liner of the diesel engine, it must be run in according to the requirements of the manual. Strictly implement the running speed (load) and time, do not be too hasty, the cylinder oil quantity is appropriately increased and the use of pure mineral oil, pay attention to monitor the temperature of the exhaust and cooling water temperature in time to find the possible failures in the running, to ensure the quality of the running.
The grade of cylinder oil and the amount of oil meet the requirements of the specification, to avoid the wrong idea that more cylinder oil is better than less. Too much cylinder oil may cause carbon formation and waste cylinder oil, too little will cause poor lubrication. The alkalinity of the cylinder oil should be determined according to the condition of the fuel oil, and the alkalinity should meet the requirements to avoid the low temperature corrosion of the cylinder piston ring of the ship engine parts and prolong the service life of the ring.
The appropriate coolant temperature shall be so that the average operating temperature is in addition to 200. C below, and can make the cylinder oil evenly distributed in the cylinder wall, reduce friction and wear, prevent carbon and low temperature corrosion, prevent ring sticking and ring breaking.
Regularly check and repair the cylinder and cylinder of ship engine parts, and make maintenance records. Analyze the wear amount and wear speed of the ring through the parameters of each cylinder. In particular, enough attention should be paid to the wear speed and shape of the cylinder, ring and ring groove. The cause of excessive wear speed must be found out and solved in time.
In addition, the wear monitoring system is set up to monitor the side and diagnose the wear of the piston ring by the number, size, morphology and composition of the abrasive particles in the lubricating oil produced during the operation of the firewood fittings.
