这要看你的设备的工作状况，哪种更合适。46，68只是抗磨液压油中粘度等级不同的两个，比HM46，HM68大。选择哪种粘度等级主要取决于系统启动时的工作温度和所用泵的类型。选择合适的粘度很重要。液压油粘度过高，液压系统能量损失大，系统效率低，油泵吸油困难。粘度太小，油泵内泄漏量大，容积损失增大，也降低了系统效率。良好的抗磨液压油，粘度指数高，高温性能好，低温易流动，能耗低。经济，长期使用不产生油泥，有效保持液压系统高度清洁。质量要求:汽车、工程机械等液压系统使用液压油作为工作介质。It depends on the working condition of your equipment, which is more suitable. 46,68 is only two brands of antiwear hydraulic oil with different viscosity grade, which is bigger than HM46, HM68. Which viscosity class to choose depends mainly on the system start-up temperature and the type of pump used. It is important to choose the right viscosity. The hydraulic oil viscosity is too high, the hydraulic system energy loss is big, the system efficiency is low, the oil pump absorbs the oil difficultly. Viscosity is too small, pump leakage, volume loss increases, but also reduce the efficiency of the system. Good anti-wear hydraulic oil, high viscosity index, high temperature performance, low temperature easy flow, low energy consumption. Economic and durable, long-term use does not produce sludge, effectively maintain the hydraulic system is highly clean. Quality Requirements: automobile, construction machinery and other hydraulic systems using hydraulic oil as the
