农用柴油机气缸套磨损与对策

CYLINDER LINER ABRASION OF DIESEL ENGINE AND PREVENTION MEASURES

本文从农机运用的观点对农用柴油机、拖拉机气缸套内壁磨损的原因、特征及预防措施进行了系统的分析研究。结果表明,气缸套内壁磨损形式主要分为磨粒磨损、粘着磨损、腐蚀磨损及综合磨损,不同的磨损形式其磨损特征及预防措施亦不相同。当发动机某一使用工况下工作时,某种磨损形式(或几种磨损形式)会起主导作用,其外观形貌特征相应地表现为它的磨损特征,这就为正确判断分析发动机气缸套内壁磨损的原因及采取正确的预防措施提供了科学依据。

Studies on the reasons and features of the cylinder liner abrasion in agricultural diesel engines showed that the abrasive forms were mainly abrasive particle abrasion,adhesion abrasion,corrosive wear and comprehensive abrasion.The forms determined the abrasion features,which could be used to analyse the abrasive reason and take correct prevention measures.
