内部故障产生的内部原因有
The internal causes of the internal faults are
材料和油料的性质,在设计制造过程中,要根据柴油发电机组零件的工作性质和特点正确的选择材料。材料选用不当,材质不符合规定和选用了不适当的代用品从而导致零件的产生磨损。腹足、变形,疲劳损伤,破裂和老化,等现象的主要原因,内燃机上所用的各种材料和油料的性质,归纳,起来不外乎是物流性质,华夏性质及机械性质的三个方面,内燃机的许多故障正是由于外界的因素的影响,通过这些性质而起作用的结果,如金属材料受力过大后会产生变形和裂纹甚至折断,在高温作用下回氧化,在各种载荷下回产生疲劳损伤,非金属材料会产生老化,油料中所含的酸性物质对金属有腐烛作用,并且会使油料变质等。
In the process of design and manufacture, the material should be selected correctly according to the working characteristics and characteristics of the diesel generator set. Improper selection of materials, material does not meet the requirements and the use of inappropriate substitutes, leading to wear and tear of parts. Gastropods, deformation, fatigue damage, rupture and aging, the main reason of such phenomena, summarized by the internal combustion engine of various materials and oil properties, it is nothing more than three aspects of Chinese logistics properties, properties and mechanical properties, many malfunction of the internal combustion engine is due to influence of external factors, which play a role the results of these properties, such as metal material excessive force will produce deformation and cracks or even broken, next time in high temperature oxidation, fatigue damage under different load next time, non-metallic materials will produce aging, acidic substances contained in oil with corrosion action on metals, and the deterioration of oil.
