施工机械对于润滑油的要求不但品种逐渐增多,而且对其性能的要求也相当严格,如果用油不当,会对机械的寿命和使用性能产生很大的影响。不同的润滑油由不同的成分组成,各有不同的用途。即使油品种相同,若厂家不同,也会对发动机产生很大的影响。例如,1986年,我公司从无锡某炼油厂购进一批11号柴油机润滑油,简称无锡11号油。这批油的说明书和出厂合格证俱全。我公司地处江南,霜冻期短,冬季最低气温不低于-10℃。所以,冬季施工中的柴油发动机均使用11号柴油机润滑油。按规定将在役的
The requirements for lubricants in construction machinery are not only gradually increasing, but also their performance requirements are very strict. If oil is used improperly, it will have a great impact on the life and performance of the machinery. Different lubricating oils are composed of different ingredients and each have different uses. Even if the oil type is the same, if the manufacturer is different, it will have a great impact on the engine. For example, in 1986, our company purchased a group of No. 11 diesel engine lubricants from a refinery in Wuxi, referred to as Wuxi No. 11 oil for short. This batch of oil’s specification and factory certificate are all available. My company is located in the south of the Yangtze River, the frost period is short, and the minimum temperature in winter is not lower than -10°C. Therefore, the 11th diesel engine oil is used for diesel engines in winter construction. According to regulations will be in service
