润滑油和润滑脂使用误区!

发布时间2019-07-11  来源:http://www.wunqdctk.com

  机油可分为汽油机油和柴油机油。汽油机和柴油机虽然工作在高温、高压、高负荷条件下,但两者之间仍存在较大的差异。
  Oil can be divided into gasoline engine oil and diesel engine oil. Although gasoline engine and diesel engine work under high temperature, high pressure and high load conditions, there are still great differences between them.
  首先,压缩比汽油发动机多一倍,柴油发动机,它的主要部件受到的压力比汽油发动机大得多,而且有些部件的材料都是一样的。例如,主轴承和连杆轴承壳体的汽油可用巴布钻头,质地柔软,耐腐蚀性好,而柴油机轴承必须采用高性能铅青铜或铅合金材料,但耐腐蚀性较差的材料。
  First of all, compression is twice as much as gasoline engine. Diesel engine, its main parts are under much greater pressure than gasoline engine, and some parts are made of the same material. For example, gasoline for the main bearing and rod bearing shell can be used as a cataplasm bit, which has soft texture and good corrosion resistance, while diesel engine bearings must be made of high performance lead bronze or lead alloy materials, but the corrosion resistance is poor.
  因此,在柴油机机油中加入一些防锈剂,以便在轴承表面产生一层保护膜,减少轴承的腐蚀,提高其耐磨性。由于汽油机机油不含防锈剂,如果将其加到柴油机上,轴承壳体在使用中很容易出现斑点、亚麻布、甚至片脱落,机油很快就会变质。
  Therefore, some antirust agents are added to diesel engine oil in order to produce a protective film on the bearing surface, reduce the corrosion of the bearing and improve its wear resistance. Because gasoline engine oil does not contain antirust agent, if it is added to the diesel engine, bearing shell is prone to spot, linen, or even flake fall off in use, and the oil will soon deteriorate.
  此外,含硫量柴油比汽油大,燃烧过程中的有害物质会形成硫酸或亚硫酸盐,随着高温高压燃气管道进入油底壳,加速氧化和恶化的石油,所以它需要添加抗氧化剂在柴油机油,油碱。如果有酸性气体传感器,可以起到中性的作用,不会使油的氧化速度过快。而汽油机机油中不含这种添加剂,因此要中性,如果用于柴油机,由于酸性气体的腐蚀变质失效很快。因此,需要柴油发动机的机油和柴油汽车不能用机油代替汽油发动机。
  In addition, diesel oil contains more sulfur than gasoline, and harmful substances in combustion process will form sulfuric acid or sulfite. As high temperature and high pressure gas pipelines enter the oil pan, accelerating oxidation and deterioration of oil, it needs to add antioxidants in diesel oil, oil base. If there is an acid gas sensor, it can play a neutral role and will not make the oxidation of oil too fast. The gasoline engine oil does not contain this additive, so it should be neutral. If it is used in diesel engine, it will lose efficacy quickly due to the corrosion of acid gas. Therefore, the oil which needs diesel engine and diesel car can not replace gasoline engine with engine oil.
  2. 国产汽车使用进口石油
  2. Domestic automobiles use imported petroleum

  现在有些人认为进口石油一定比国产石油好,所以在国产汽车上使用进口石油,尤其是在新车上,往往会有很多缺陷。例如,大多数进口石油粘度较低,不能适应国内粘度对石油的需求,结合国内发动机附件材料热膨胀系统和进口汽车的配合间隙,和大多数中国制造的发动机没有油散热器,如果采用进口石油,因为石油稀释机油压力低,甚至不能满足规定的工作压力,不能满足正常的需要润滑,磨损的引擎。
  Now some people think that imported petroleum must be better than domestic petroleum, so using imported petroleum in domestic cars, especially in new cars, often has many defects. For example, the viscosity of most imported petroleum is low and can not meet the demand of domestic viscosities for petroleum. Considering the thermal expansion system of domestic engine accessories and the matching clearance of imported automobiles, and most Chinese-made engines do not have oil radiators, if imported petroleum is used, the pressure of oil diluted by petroleum is low, even can not meet the requirements. The fixed working pressure can not meet the normal needs of lubrication, wear engine.
  3.盲目选择润滑油等级
  3. Blind selection of lubricant grade
  润滑油的润滑质量好与坏,直接关系到发动机的使用寿命的长度,尤其是新型的汽车润滑油要求非常严格,选择润滑油,更换时,如何取代等应符合制造商的规定。
  Lubrication quality of lubricating oil is directly related to the length of engine life, especially the new type of automobile lubricating oil requirements are very strict, the choice of lubricating oil, replacement, how to meet the requirements of manufacturers.
  在选用机油时,既要注意质量等级,又要注意粘度等级。然后根据温度、负载水平进行粘度的选择。优质的机油能保证发动机良好的润滑性能,减少磨损,延长发动机的使用寿命,延长机油的换油周期。在选择机油粘度时,除了温度条件外,还应保证发动机的润滑和密封条件,尽量选用低粘度机油,以节省燃油。
  When selecting engine oil, attention should be paid to both quality grade and viscosity grade. Then the viscosity is selected according to the temperature and load level. High quality oil can ensure good lubrication performance, reduce wear and tear, prolong the service life of the engine, and prolong the oil exchange cycle. When choosing the oil viscosity, besides the temperature conditions, the lubrication and sealing conditions of the engine should be guaranteed, and the low viscosity oil should be selected as far as possible to save fuel.
