摘　　要：许多工程机械由于使用环境恶劣,温差较大。在低温时普通液压油容易凝固,导致液压系统出现故障,但是在常温下,如果使用低温液压油其黏度很低,会增大液压元件本身的磨损,造成系统效率偏低。所以选择能在低温及常温下使用的液压油显得十分重要。Mainifold machines are used in hard conditions and biggish difference in temperature. The normal hydraulic oil is to be curdled in low temperature lead to malfunction of hydraulic system, however it will result in the abrasion of hydraulic elements and inefficient system due to the low oil viscosity of temperature hydraulic oil in normal temperature. So it is very important to choose the hydraulic oil working in low temperature and normal temperature.
