一、概况随着造船工业的不断发展,近十多年来,在船用柴油机气缸套的研究方面又有新的进展。硼铸铁材料的广泛使用;设计结构的不断改进;两段缸套的出现;润滑条件的改善,使气缸套的磨损大为降低,使用寿命不断提高,增长了柴油机的检修间隔期。在此同时,在长期实践基础上所提出的缸套表面质量的检验规范,具有很大的实用价值。本文将就国内外船用柴 First, the general situation With the continuous development of shipbuilding industry, nearly 10 years, marine diesel engine cylinder liner in the research has made new progress. The extensive use of boron cast iron materials; the continuous improvement of the design structure; the appearance of two-stage cylinder liner; the improvement of lubrication conditions greatly reduces the wear of the cylinder liner, prolongs the service life and increases the diesel engine overhaul interval. At the same time, the inspection standard of cylinder surface quality proposed on the basis of long-term practice has great practical value. This article will be on domestic and international marine diesel
