一、目的内燃机车在出厂后,约经过18～20个月左右的时间,便会发生柴油机缸套漏水故障。因而在间隔为30个月的厂修周期内,就需要经常进行临修和由工厂派人修理。柴油机缸套漏水,是因穴蚀和O形环受缸套振动以及热传导的影响发生老化变形而引起的,而穴蚀又是水冷式柴油机特有的现象。冷却水若从缸套四周漏出,与机油混合并乳化,则会影响润滑性能,以致使柴油机发生各种各样的故障。柴油机缸套漏水的途径及原因见图1。
First, the purpose After the diesel locomotive factory, about 18 to 20 months or so, will occur diesel engine cylinder cover leakage failure. Therefore, in the interval of 30 months of factory repair cycle, you need to carry out regular repair and repaired by the factory. Diesel engine cylinder liner leakage is due to cavitation and O-ring cylinder liner vibration and heat conduction caused by the aging deformation, and cavitation is a water-cooled diesel engine unique phenomenon. If the cooling water leaks from the periphery of the cylinder liner and mixes with the oil and emulsifies, the lubricating performance will be affected, causing various failures of the diesel engine. Diesel engine cylinder liner leakage and the reasons shown in Figure 1.
