广大机手对发动机保养时,普遍存在着只管加添机油,到时不换机油,更谈不上定期清洗润滑油道。这问题必须重视,因为机油通过机油泵,它将分配到各个零件的配合面形成油膜,使之将直接摩擦变成间接摩擦,借以改善磨损条件。如果到时不换机油和不清洗机油道,而长期使用的机油将会变质、粘度大大降低,润滑性降低、机温升高。加之机油道不清洗,使之零件间磨损的铁屑、杂物积存过多,在机油中形成了硬度较大的磨料,甚至堵塞机油道。这样不仅使零件配合面迅速磨损,大大缩短了机器使用寿命,出现事故。如烧瓦、连杆熔洁甩断曲轴等。
The majority of the engine maintenance of the engine, the prevalence of just add additional oil to the time do not change the oil, let alone regular cleaning of lubricating oil Road. This problem must be emphasized because the oil passes through the oil pump and it distributes the oil film to the mating surfaces of the various parts so that the direct and indirect friction will improve the wear conditions. If the time does not change the oil and does not clean the oil path, and long-term use of oil will deteriorate, significantly reduce viscosity, reduce lubrication, machine temperature. Coupled with the machine oil is not clean, so that parts of the wear of iron filings, debris accumulated too much in the oil to form a larger abrasive, and even plug the machine oil. This will not only wear parts quickly with the mating surface, greatly reducing the service life of the machine, an accident. Such as burning tile, connecting rod melting off crankshaft and so on.
