梅州大埔县壳牌海得力液压油-佳度锂基脂销售46号比较好，经济，46跟68号在粘性和闪点上有区别。46号稀一点，68号稠一点。一般来讲，冬天气温低，用粘度低一点的46#液压油，夏天气温高，用粘度高一点的68号液压油，特殊情况特殊对待。两者在闪点上也存在差别，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得很不错。选用合适的黏度是重要的，液压油黏度太大，液压系统能量损失大，系统效率低，油泵吸油困难；黏度太小，油泵内渗漏量大，容积损失增加，同样降低系统效率。No. 46 is better, economical and durable, and No. 46 is different from No. 68 in stickiness and flash point. 46 is thinner, 68 is thicker. Generally speaking, low winter temperature, low viscosity with 46 # hydraulic oil, high summer temperature, high viscosity with 68 # hydraulic oil, special treatment. There are also differences in flash points between the two. As we all know, today's hydraulic oil also has its own flash points, so now hydraulic oil no. 46 and No. 68 will also have differences in flash points, no. 46 hydraulic fluid has a relatively low flash point, so it is suitable for different industries and different environments, but both do a good job in anti-wear and anti-oxidation. It is important to select the appropriate viscosity, hydraulic oil viscosity is too large, hydraulic system energy loss, low system efficiency, oil pump difficult to absorb; viscosity is too small, oil pump leakage, volume loss increase, it also reduces the efficiency of the system.
