柱塞泵对油品黏度要求更为苛刻,其最佳工作黏度为10~1100 mm2/s。液压油在低温时的润滑表现主要以运动黏度进行衡量。文章从液压油低温性能出发,分析比较了国内外标准对多级液压油的低温黏度和倾点要求,同时对昆仑HV N46液压油性能和黏温性能进行了分析阐述,并提供了昆仑HV N46的低温使用范围。
Plunger pump oil viscosity requirements more demanding, the best working viscosity of 10 ~ 1100 mm2 / s. Lubrication performance of hydraulic oil at low temperature is mainly measured by the kinematic viscosity. Based on the low temperature performance of hydraulic oil, this paper analyzes and compares the low temperature viscosity and pour point requirements of multistage hydraulic oil both at home and abroad. At the same time, the performance and viscosity-temperature performance of Kunlun HV N46 hydraulic oil are analyzed and explained. Kunlun HV N46 The use of low-temperature range.
