洛阳市涧西区西工壳牌液压油-导轨油销售处The viscosity of hydraulic oil No. 46 is relatively low, while the viscosity of hydraulic oil No. 68 is relatively high. Generally speaking, if the viscosity is high, the formed oil film is relatively thick. In winter when the temperature is low, it is recommended to choose hydraulic oil No. 46. Another point is that there is a difference in flash point. As we all know, modern hydraulic oil also has its own flash point. Therefore, there is a difference in flash point between hydraulic oil No. 46 and No. 68. Hydraulic oil No. 46 has a relatively lower flash point, making it suitable for different industries and environments. However, both have done well in anti-wear and anti-oxidation properties

　　46号液压油和68号压油的区别主要是粘度性能不同和倾点不同。以下是这两者的具体区别:

　　1、倾点不同:低凝液压油的液压系统在机械传动中发挥着重要的作用，在一些环境较为寒冷、温差大的条件下，液压系统在使用时常常使用液压油进行润滑，所以倾点要求很重要，-15或者-30这样，才能达到低温条件下的液压油正常使用。

　　2、46号液压油的粘度比较低，而68号液压油的粘度比较高，一般来说粘度比较高的话，形成的油膜比较厚，在冬天气温比较低的情况下，建议选择46号液压油。另外一点则是在闪点存在差别，众所周知，现在的液压油，也是有属于自己的闪点，所以现在46号和68号液压油，在闪点方面也会有区别，46号液压油的闪点相对低一点，因此适合不同的行业，不同的环境下使用，但是两者在抗磨，以及抗氧化性方面都做的很不错
