韶关武江新华、惠民壳牌液压油-齿轮油经销部(L) proper viscosity and good viscosity-temperature performance to ensure that the hydraulic components in the operating pressure and temperature changes under the conditions of good lubrication, cooling and sealing. (2) good extreme pressure and anti-wear performance to ensure that the friction pairs in the oil pump, hydraulic motor, control valve and oil cylinder get normal lubrication under high pressure and high speed and harsh conditions to reduce wear. (3) excellent anti-oxidation stability, hydrolytic stability and thermal stability to resist the influence or action of air, moisture, high temperature, high pressure, etc. . (4) good anti-foaming property and air release value to ensure that the foam produced under the condition of severe mechanical agitation in operation can disappear quickly, and can release the air mixed in the oil in a relatively short time, in order to achieve accurate, sensitive and smooth transmission of static pressure. (5) 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. (6) good rust resistance to prevent metal surface rust(l)合适的粘度和***的粘温性能，以***液压元件在工作压力和工作温度发生变化的条件下得到***润滑、冷却和密封。
(2)***的极压抗磨性，以***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。
(3)优良的***化***性、水解***性和热稳定性，以抵抗空气、水分和高温、高压等因素的影响或作用，使其不易老化变质，延长使用寿命。
(4)***的抗泡性和空气释放值，以***在运转中受到机械剧烈搅拌的条件下产生的泡沫能迅速消失;并能将混入油中的空气在较短时间内释放出来，以实现准确、灵敏、平稳地传递静压。
(5)***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。
(6)***的防锈性，以防止金属表面锈蚀
