赣州全南大吉山镇美孚液压油-空压机油经销啦1、适用的地区不同
46#抗磨液压油适用于温带地区，68#抗磨液压油适用于亚热带地区。
2、粘度不同
一般温度下，68号液压油粘度比46号液压油高
3、功效不同
46号液压油：有良好的极压抗磨性，能够保证油泵、液压马达、控制阀和油缸中的摩擦副在高压、高速苛刻条件下得到正常的润滑，减少磨损。
68号液压油：有良好的抗乳化性，能与混入油中的水分迅速分离，以免形成乳化液，引起液压系统的金属材质锈蚀和降低使用性能。1. The applicable area different 46 # antiwear hydraulic oil is suitable for the temperate zone, 68 # antiwear hydraulic oil is suitable for the subtropical zone. 2. The viscosity of no. 68 hydraulic oil is higher than that of No. 46 hydraulic oil under different general temperature, can ensure that the oil pump, hydraulic motor, control valve and cylinder of the friction pair in high-pressure, high-speed harsh conditions get normal lubrication, reduce wear. No. 68 hydraulic oil: has good anti-emulsification, can be quickly separated from the water mixed in the oil to avoid the formation of emulsion, causing the hydraulic system of metal corrosion and reduce performance.
