扬州市邗江区公道镇代理美孚液压油-机床导轨油​ 液压油的粘度分级
液压油粘度高雀新的分级方法是用
40 ℃运动粘度的第一中心值为粘度牌号，
共分为八个粘度等级。液压油的粘度取决于温度，如果液压系统（压力较高）的温度很高（比如，工作产生的温度，和当时环境的温度），那么就应大笑该使滚念含用68号液压油，（在高温地区使用，或者是夏天）​Hydraulic oil viscosity classification, hydraulic oil viscosity high new classification method is to use 40 ° C viscosity of the first center for the viscosity brand, pided into a total of eight viscosity grades. The viscosity of hydraulic oil depends on the temperature. If the temperature of the hydraulic system (the pressure is high) is very high (for example, the temperature of the operation, and the temperature of the environment at that time) , then you should laugh, used in hot climates, or in summer
