焦作武陟县修武美孚220齿轮油-透平油销售啦轮油220和320的核心区别在于粘度等级,该等级依据ISO VG标准划分,数值代表40℃时的运动粘度(单位:mm²/s)。220号齿轮油的运动粘度范围为198-242mm²/s,流动性较好;320号的运动粘度范围为288-352mm²/s,粘稠度更高。The core difference between wheel oil 220 and 320 lies in the viscosity grade, which is classified according to the ISO VG standard and represents the kinematic viscosity at 40 ℃ (unit: mm ²/s). The kinematic viscosity range of 220 gear oil is 198-242mm ²/s, with good fluidity; The kinematic viscosity range of 320 is 288-352mm ²/s, with higher viscosity
