Abstract
The base oil of hydraulic oil,25 transformer oil and 8 aviation oil were selected to study the influence of low temperature on lubricating oil's performance through measuring the low-temperature kinematic viscosity of oil samples mentioned above and mixed oil samples in the range of-10~-40 ℃.The viscosity of oil samples increased gradually with the decrease of temperature,and the lower the temperature was,the more rapid viscosity of oil samples increased.When the temperature was higher than-20 ℃,the viscosity increase of oil samples was slower with the decrease of temperature;When the temperature decreased to below-20 ℃,the viscosity increase of oil samples was faster with the decrease of temperature.Additionally,the phenomena of experiments were explained.These results could provide basis for the application and development of lubricating oil at low temperature.
