It was reported on May 17 that the domestic low-speed marine diesel engine assembled by Dalian Marine Diesel Engine Factory has completed the development and construction of the 8K90MC-C engine with a power of 49,760 horsepower after welding and processing. Manufactured blank. The 8K90MC -C machine manufactured by Dalian Chuanchai is used for large container ships with 4250 boxes. Its technical and economic indicators represent the advanced level of the world's marine main engines, and currently there are only a few engine factories in the world that can manufacture them. The large container ships previously built by Chinese shipyards all imported main engines from Japan and South Korea. During the "Tenth Five-Year Plan" period, Dalian Chuanchai made solid preparations for the construction of super-large main engines through technological transformation, building factories, purchasing equipment, and strengthening its strength. In order to ensure that the 8K90MC-C machine is built according to the plan, Dalian Chuanchai carefully organized and held several special meetings for deployment, and implemented the self-made parts in the factory and the supporting parts at home and abroad one by one. At the same time, the factory also set up a research team to tackle key problems such as hoisting capacity, unsuitability of process equipment, and digestion and absorption of the new design of the main engine, so that the machine can be better guaranteed in terms of technical preparation, process measures, process control, and supporting organization. , Created conditions for smooth assembly on the test bench. The assembly work was handed over in early June. On April 11, the 8K90MC-C machine began to assemble the test bench in Dalian Chuanchai. On April 24, the main engine crankshaft with a length of 14 meters and a weight of 237 tons was successfully hoisted onto the test bench. Due to the long length of the crankshaft, the heavy tonnage, and the lack of experience in the first hoisting, the hoisting work was difficult. The technicians carefully calculated, determined the lifting point, selected the appropriate spreader, and the crane workers cooperated closely. After trial lifting and adjustment, the crankshaft was finally balanced to ensure a smooth lifting. At present, the assembly work of the 8K90MC-C machine is proceeding in an orderly manner as planned, and will be handed over at the end of May and early June.
