柴油机水温过高通常会造成散热器内冷却液沸腾、柴油机功率下降、润滑油黏度降低、柴油机零部件间摩擦加剧,甚至会导致柴油机拉缸、汽缸垫烧毁等严重故障。本文总结柴油机高温的主要原因,同时提出一些改进措施:1.长时间超负荷作业柴油机长时间超负荷作业,会使其油耗增加、热负荷升高,从而出现水温过高现象。为此,应避免柴油机长时间超负荷作业。
Diesel engine water temperature is usually too high will cause coolant boiling within the radiator, diesel engine power decreases, the viscosity of lubricating oil, diesel engine parts friction between the worse, and even lead to diesel cylinder, cylinder head burned and other serious problems. This article summarizes the main reason for the high temperature of diesel engine, at the same time proposes some improvements: 1. Long-term overload of diesel engine overworked for a long time, will increase its fuel consumption, heat load, resulting in water temperature is too high. To this end, diesel engines should be avoided overloaded for a long time.
