一、前言在总路线的光辉照耀下,各条生产战线都在飞跃发展,船舶运输任务也随着迅速增长。为了适应船舶建造的需要,主机的供应制造,就成为一个重要的课题,重型低速柴油机的经济价值、性能与使用时的劳动条件都较好,但要制造这种大型的重型柴油机,则技术要求较高。我厂过去在柴油机方面仅以修配为主,没有制造过较大马力的柴油机。解放后虽已在迅速发展,能够自制各种中速和高速中型柴油机的另件,而且有不少主要另件的质量已达到国际水平,但却从未制造过一台完整的较大马力的柴油机。1958年6月底,为了适应今后航运事业发展 I. INTRODUCTION Under the brilliance of the general line, various production fronts are developing rapidly, and the task of ship transportation has also grown rapidly. In order to meet the needs of shipbuilding, the supply of main engines has become an important issue. The economic value, performance, and working conditions of heavy-duty low-speed diesel engines are all better. However, technical requirements are required to produce such large-scale heavy-duty diesel engines. Higher. In the past, our factory only focused on the diesel engine and did not manufacture diesel engines with large horsepower. After liberation, although it has been developing rapidly, it is able to make all kinds of medium-speed and high-speed medium-duty diesel engine parts, and many of the major parts have reached the international level, but they have never produced a complete, relatively large horsepower. diesel engine. At the end of June 1958, in order to adapt to the future development of the shipping industry
