本文扼要介绍了北京型、东风_7型机车用12V240ZJ型柴油机提高机油过滤精度,改进机油系统,降低气缸套、轴承等运动副磨损,延长使用寿命,减少柴油机故障的试验研究与改进情况。针对柴油机原机油系统及机油滤清器过滤精度不高,气缸套及轴承拉伤、磨损等问题研制和应用了新的过滤精度较高的纸质滤芯机油滤清器,并对整个机油系统也进行了分析研究,采取了相应措施.
This article briefly introduces the experimental research and improvement of Beijing type and Dongfeng type-7 diesel locomotive 12V240ZJ diesel engine to improve the precision of oil filtration, improve the oil system, reduce the wear of the cylinder liner and bearing, prolong the service life and reduce the diesel engine failure. For the original diesel engine oil system and oil filter filter accuracy is not high, the cylinder liner and bearing strain, wear and other issues developed and applied a new high-precision filter paper filter oil filter, and the entire oil system Carried out analysis and research, took corresponding measures.
