DK28 diesel engine parts introduce cylinder routine maintenance methods

After installing a new ring or replacing the cylinder liner of Marine diesel engine accessories, it must be run in according to the instructions. Strictly implement the speed (load) and time of running-in, can not be rushed, the amount of cylinder oil is appropriately increased and the use of pure mineral oil, pay attention to monitoring the discharge temperature and cooling water temperature in time to find possible faults in running-in to ensure the quality of running-in.

The brand and amount of cylinder oil meet the requirements of the manual, and the wrong idea that more cylinder oil is better than less cylinder oil should be avoided. Too much cylinder oil may cause carbon pooling and waste cylinder oil, too little will cause poor lubrication. The alkalinity of the cylinder oil should be determined according to the situation of the fuel, and the alkalinity should meet the requirements of avoiding low-temperature corrosion of the cylinder piston ring and extending the service life of the ring.

The appropriate coolant temperature should make the average working temperature of the first ring below 200 ° C, and the cylinder oil can be distributed on the cylinder wall, reducing friction and wear, preventing carbon formation and low-temperature corrosion, and preventing sticking rings and broken rings.

Regular cylinder maintenance, maintenance records, through the parameters of each cylinder analysis of ring wear and wear speed. In particular, sufficient attention should be paid to the wear speed and shape of the cylinder, ring and ring groove, and the cause of excessive wear speed must be found out and solved in time. The wear monitoring system is set up to monitor and diagnose the wear of piston rings by the number, size, shape and composition of the wear particles in the lubricating oil produced during the operation of the diesel engine.
