船用主机制造工艺是以机械工业发展为基础,并与造船工艺及其发展密切相关的。第二次世界大战结束后的三十年,船舶建造一直朝着大型化和高速化方向发展。这个时期船用柴油机的主要指标是增加单缸功率,低速柴油机单缸功率达到4,600～5,500马力/缸,单机功率达47,000马力;中速柴油机单缸功率达到1800～2500马力/缸,单机功率达34,000马力。汽轮机单机功率达45,000马力。由于世界能源危机对造船航运界的冲击,以及资本主义世界经
The marine host manufacturing process is based on the development of the machinery industry and is closely related to the shipbuilding process and its development. Thirty years after the end of the Second World War, shipbuilding has been developing toward large scale and high speed. The main indicator of marine diesel engines during this period was to increase the power of single cylinders. The single cylinder power of low-speed diesel engines reached 4,600 to 5,500 hp/cylinder and the single-machine power reached 47,000 hp; the single-cylinder diesel engine of medium-speed diesel engines reached 1,800 to 2,500 hp/cylinder, with a stand-alone power of 34,000. horsepower. Steam turbines stand up to 45,000 horsepower. Due to the impact of the world energy crisis on the shipbuilding and shipping industry and the capitalist world economy
