1、船舶柴油機氣缸套的磨損及預防措施[摘要]氣缸套是船舶柴油機的重要零件之一,因其內(nèi)壁工作條件十分惡劣,很容易發(fā)生磨損,其磨損情況將直接影響氣缸套與活塞環(huán)之間的密封性能,對柴油機的啟動、功率損耗、燃油和潤滑油的消耗、使用壽命以及排氣的顏色等都有著重大的影響。因此,正確地認識氣缸套磨損的類型及其產(chǎn)生的機理,并采取積極的預防措施和修復工藝,對于提高船舶柴油機的整機壽命和機械設備的使用效益有十分重要的意義。本文探討了船舶柴油機氣缸套磨損的特征及形成規(guī)律,全面而系統(tǒng)地分析了船舶柴油機氣缸套磨損的類型及其產(chǎn)生的機理,并在此基礎上,提出了在使用和保修中減少船舶柴油機氣缸套磨損的預防措施及修復工藝
