柴油机工作可靠性主要决定于机体、曲轴、活塞、连杆等零部件的可靠性,这些零部件的故障都可能导致柴油机的严重破坏。因此,提高柴油机运用可靠性有极其重要的意义。12240型柴油机投入批量生产以来,制造工艺及技术水平不断提高,主要零部件的设计研究和改进工作,在一些兄弟单位的大力协助下有了较大的进展。然而,随着柴油机主要零部件可靠性的研究和改进工作不断深入,质量不断提高,柴油机的辅助装置——冷却水、机油和燃油等管路系统的零部件的结构可靠性又成为矛盾的主要方面,它在运用中暴露出来的
Diesel reliability mainly depends on the reliability of the body, crankshaft, piston, connecting rod and other components, the failure of these components may lead to serious damage to the diesel engine. Therefore, improving the reliability of diesel engine use is extremely important. Since the 12240 diesel engine was put into mass production, the manufacturing technology and technical level have been continuously improved. The design, research and improvement of major components and parts have made great progress with the help of some brothers and units. However, as the research and improvement on the reliability of diesel engine components continue to deepen and the quality continues to rise, the structural reliability of the components of diesel engine piping systems, such as cooling water, oil and fuel, has become the major contradiction Aspects, it is exposed in the use of
